These implementation examples are merely illustrative, and the present invention can be implemented in various modifications and improvements based on the knowledge of those skilled in the art. In the present specification and drawings, components having the same reference numerals denote the same components.

(Embodiment 1)
FIG. 1 shows an example of the architecture of the first embodiment. As shown in the figure, the device dependent unit dependent on a standard or manufacturing vendor that conforms from the bottom, middleware that hides the difference between the hardware and software of the device dependent unit, and a general-purpose device-independent application that does not depend on the device. The middleware and the device independent application are connected by the device independent API 21, the middleware and the software of the device dependent part and the OAM are connected by the device dependent API 23, and the middleware and the NE management / control unit are connected by the device dependent API 25.

  In addition to the restrictions that come from processing to realize middleware or device-independent applications, which functions are device-dependent parts or device-independent applications, for example, in addition to the restrictions that come from the processing power of software, function updates By promoting according to the importance such as the frequency and realization of proprietary specifications etc., flexible and quick addition of the extension function (original function) by device-independent application is facilitated, and timely provision of service is realized. For example, it is recommended that the priority processing of the main signal and the frequency of renewal such as DBA for improving the utilization efficiency of the line be high or that it contributes to the service differentiation. Furthermore, it is preferable to use a device-independent application, since there is a small difference between the standards, generations, methods, systems, device types, and / or manufacturers of the devices to be shared.

In order to advance the generalization of at least one of the compliant standard, generation, method, system, device type, and manufacturing vendor function, it is best to at least one of the compliant standard, generation, method, system, device type, and manufacturing vendor. Not, but with a common interface. The common interface may include an interface or parameter which is not used depending on a standard, a generation, a system, a device type, and a manufacture vendor to which the device dependent part conforms. The interface, parameters, etc. correspond to the device dependent part of the middleware of the configuration of FIG. 1 or 3 and the driver of the device dependent part of the configuration of FIG. It is desirable to have a conversion function for converting and a function for automatically setting in response to an insufficient interface or parameter.

  In FIG. 1, the device-dependent unit is exemplified by device-dependent software such as hardware, drivers, firmware, applications, etc. that depend on a standard or manufacturing vendor from below, and the hardware performs MAC (Media Access Control) processing. It is illustrated by “hardware (PHY)” that performs processing from physical layer processing called “hardware (MAC)” and PHY (PHYsical sublayer) to processing related to optical transmission and reception. The hardware of the device dependent unit may include a general-purpose server, layer 2 switch, etc. in addition to these, and conversely, hardware (MAC) may not be included, or a part of hardware (PHY) It does not have to be included. For example, only light related functions may be included without low-level signal processing such as modulation / demodulation signal processing, forward error correction, encoding / decoding processing, encryption processing, etc. PCS (Physical Coding Sublayer) It does not have to include only the part that encodes the data, or it may not include the PMA (Physical Medium Attachment) that serializes the data in addition to the PCS, and the PMD (to be connected to the physical medium) Physical Medium Dependent may not be included. If the hardware of the device dependent part can be driven, controlled, operated and managed directly from the middleware without the software of the device dependent part, the software of the device dependent part may be omitted.

  The device-independent application is, for example, a control / management agent that receives communication from an EMS (Element Management System) such as an NE controller, a basic function, and an extended function. However, the device-independent application may or may not include all of these. For example, when the extension function is unnecessary, the extension function may be absent. The number of extension functions exemplified by the three ABCs may be other than three. Also, preferably, the extension functions can be added, deleted, replaced, or changed independently without adversely affecting other functions. For example, in the case where the multicast service and power saving support are used as the extension function according to the request on the service, for example, the extension function is appropriately added or deleted or replaced or changed as needed. Good.

  The basic function may be included as part of the extension function or may be substituted by the middleware subordinate. The device-independent application may not include the basic function if the extended function includes the basic function, or the middleware lower part substitutes for the basic function, or a combination thereof. When automatic setting is performed according to the setting in advance without receiving communication from the EMS, the management control agent may not input / output to / from the EMS. Furthermore, when the management setting function is not provided by the management control agent but is provided by another device-independent application, a basic function, or a device dependent unit, the management control agent may not be provided. Conversely, EMS and each device independent application may be directly input and output.

  The device independent application inputs / outputs with the device dependent unit via the middleware. Device-independent applications input and output mutually via middleware as needed. In particular, when performing control and management according to the input and output from the EMS, the device-independent application inputs and outputs from the control and management agent that inputs and outputs the EMS.

For example, a dynamic bandwidth assignment (DBA) application and protection application are embedded OAM engine of TC layer, and DWBA application and ONU registration authentication application are PLOAM engine of TC layer. The power saving application mutually exchanges information with the OMCI (ONU management and control interface) and L2 function, the MLD (Multicast Listener Discover) proxy application with the L2 function, and the low speed monitoring application (OMCI) with the OMCI. The OMCI and L2 functions operate XGEM (XGPON Encapsulation Method) Framer and Encryption.
Here, although DWBA and DBA are separated, they may be any combination, and may be a combination of DBA and DWA.

  For example, the management and control agent is an application of the maintenance operation function, and inputs and outputs information from and to the EMS in the NE management and control unit.

  The implementation of the device-independent application may have a priority. For example, the management and control agent is the first priority given the highest priority. The second or lower priority order is, for example, the order of the DBA application, the DWBA application, the power saving application, the ONU registration authentication application, the MLD proxy application, the protection application, and the low speed monitoring application (OMCI).

  The device-independent application is a device vendor, system, device type, device generation, such as ITU-T G. Time-and-Wavelength Division Multiplexing-Passive Optical Network (TWDM-PON) compliant with 989 series and ITU-T G. XG-PON conforming to the 987 series and ITU-T G. G-PON and ITU-T G.9 compliant with the 984 series. Although it is an application that operates regardless of the BPON compliant with the 983 series, or the difference between 10GE-PON compliant with IEEE802.3av or IEEE1904.1 etc. and / or GE-PON compliant with IEEE802.3ah, As an application of the extended function, it is provided only for an application for driving a function provided for some vendors, methods, types and generations via the device-independent API 21 and only for devices of some vendors, methods, types and generations It may include an app that drives the function.

  The management and control agent inputs and outputs EMS and middleware. The middleware inputs and outputs the NE management and control unit and the NE management and control information. The NE management and control unit may directly exchange NE management and control information with the EMS without passing through the middleware, or may exchange it via the management and control agent. The middleware inputs / outputs via the device-independent application and the device-independent API 21, and inputs / outputs via the device-dependent OAM, driver, firmware, hardware and device-dependent API 23.

  The middleware outputs the input as it is or in a predetermined format. For example, if the output destination is a device-independent application, the middleware takes the form of the device-independent API 21 of the format to be input to each. If the output destination is the device dependent part OAM, driver, firmware, or hardware, the middleware converts it into the format of the device dependent API 23 of the input format, or terminates and performs predetermined processing and inputs . When inputting, it is desirable that the middleware delete unnecessary input information in each input destination, and if there is insufficient information, it is collected and supplemented via another device independent API 21 or device dependent API 23. Also, when inputting to the middleware, it may be broadcasted or multicasted to be broadcast to related applications and the like.

  Although the middleware and the device dependent unit are illustrated as a single in the drawing, each may be configured of a plurality. When the hardware of the device dependent unit includes a plurality of processors, the middleware may input and output using interprocessor communication or the like across processors and hardware. Device-independent applications or device-dependent device-independent applications may be placed in the user space on a single processor as an execution program such as a DLL (Dynamic Link Library), or users on two or more processors You may arrange on space. In addition, the device-independent application may be placed in the kernel space after securing its input / output IF, or may be placed together with middleware having an IF that can be replaced independently in firmware etc. You may incorporate and recompile. The user space and the kernel space may be arbitrarily combined for each device-independent application. Device-independent applications corresponding to the same function may be implemented in both user space and kernel space. In this case, for example, one of them may be switched and selected, or both may be processed in cooperation, or the actual processing may be performed with only one of them. The same applies to the software of the device dependent unit.

  Desirably, high-speed processing such as main signal processing, DBA processing, and low-layer signal processing requires a small amount of overhead and high-speed processing, although there is a trade-off with scalability and immediacy of replacement. It is desirable to incorporate it into kernel space or firmware. The processor in which the device dependent application is placed is also the user space or kernel of the processor performing the actual processing or the processor in the vicinity of the processor from the viewpoint of the influence on other programs by the limitation of the bus and speed by interprocessor communication and occupation of the communication path. It is desirable to arrange in space or firmware. However, although the communication cost due to interprocessor communication increases in order to reduce the ability of the processor that performs actual processing or a processor in the vicinity thereof, it may be processed by a remote processor.

  It is desirable that the device-independent API 21 be provided in advance in the middleware, assuming an extended function to be added later, but if necessary, it is added in the form of suppressing modification of the device-dependent API 23 and other device-independent applications You may delete it.

  Although the configuration in FIG. 1 is described on the premise of an OLT (Optical Line Terminal) of a PON compliant with ITU-T recommendations such as TWDM-PON, it may be an ONU, or an ITU other than TWDM-PON. -It may be either OLT or ONU of PON compliant with T recommendation, or it may be PON compliant with IEEE standard such as GE-PON, 10GE-PON, etc. TC layer or PMD layer corresponds to the corresponding layer It is the same if it reads again.

Embodiment 1-1
The TWDM-PON mainly has eight functions: PON multicast function, power saving control function, frequency / time synchronization function, protection function, maintenance operation function, L2 type signal processing function, PON access control function, PON main signal processing function Take the case of having.

  FIG. 7 shows an example of the flow of signals / information between the main eight functions. The PON main signal processing function may be connected to PMD (outside the main 8 functions), PON access control function, maintenance operation function (PLOAM processing, OMCI processing) and L2 main signal processing function, PON multicast function, power saving control The function, frequency / time synchronization function, and protection function may be connected to the group consisting of the maintenance operation function, the L2 main signal processing function, the PON access control function, and the PMD. Each function will be described with reference to FIGS. 8 to 17.

  FIG. 8 is a diagram of a PON main signal processing function. As processing for configuring the PON main signal processing function, PHY adaptation, framing, and service adaptation may be provided in the processing order of upstream signals (in the reverse direction for downstream signal processing). These processes may be composed of basic processes such as synchronous block generation / extraction, scrambling / descrambling, FEC decoding / encoding, frame generation / separation, GEM encapsulation, fragment processing, and encryption. PHY adaptation may include synchronous block extraction, descrambling and FEC decoding in the order of processing of uplink signals, and FEC encoding, scrambling and synchronization block generation in the order of downlink signal processing. The equivalent processing may be realized by a combination of basic processing without processing of PHY adaptation, framing, and service adaptation. Also, the order may be reversed. For example, FEC processing may be provided other than PHY adaptation.

  In this main function, when processing 10 Gbit / s / λ and 2.5 Gbit / s / λ for each wavelength, stream processing for 10 Gbit / s / λ and 2.5 Gbit / s / λ or more is If multiple wavelengths are processed, multiple wavelengths can be obtained.

  FIG. 9 is a diagram of a PON access control function. The processing to be configured includes ONU registration / authentication, DBA, λ setting switching (DWA). These processes may consist of basic processes. For example, ONU registration / authentication constitute initial processing: ranging, authentication deletion and registration, start / stop, DBA received bandwidth request, traffic measurement, history holding, allocation calculation, allocation processing, setting switching calculation, setting switching processing, setting switching All or some of situation grasping, λ setting switching consists of band request reception, traffic measurement, history holding, allocation calculation, assignment process, setting switching calculation, setting switching process, setting switching situation grasping or all or some of them It may be done. The same process may be realized by a combination of basic processes without providing ONU registration / authentication, DBA, λ setting switching (DWA). Also, the order may be reversed. In this main function, ONU fast start-up, BWMap within the DBA cycle, hitless λ setting switching, etc. are obtained as necessary.

  As an example of function assignment, as registration / authentication, time-critical ranging processing may be an apparatus dependent unit, and subsequent authentication or key exchange may be an application. In the DBA · λ setting switching, a simple repetitive process may be performed on the device dependent unit, and reflection on the ideal state may be performed on the application.

  FIG. 10 is a diagram of the L2 main signal processing function. The processing to be configured includes MAC learning, VLAN control, path control, band control, priority control, delay control, and Copy. These processes may be configured from the basic processes of address management, Classifier, Modifier, Policer / Shaper, Cross Connect, Queue, Scheduler, Copy, and traffic monitor. The MAC learning, VLAN control, path control, band control, priority control, delay control, and copy may not be provided, and equivalent processing may be realized by a combination of basic processing. Also, the order may be reversed.

  In this main function, when processing 10 Gbit / s / λ and 2.5 Gbit / s / λ for each wavelength, stream processing for 10 Gbit / s / λ and 2.5 Gbit / s / λ or more is If multiple wavelengths are processed, multiple wavelengths can be obtained. FIG. 11 is a diagram of maintenance operation function (1) device setting / management. As processing to configure, there are device settings (manual, batch, automatic, operation timing) of ONU / OSU / OLT / SW, setting backup, FW update, device control (reset), and redundant configuration correspondence. These processes may be composed of CLI-IF which is basic process, operation IF, general-purpose Config-IF (NETCONF / SNMP etc.), and table management. The same processing may be realized by a combination of basic processing without device setting, setting backup, FW update, device control, and redundant configuration correspondence. Also, the order may be reversed.

  In this main function, within 100 ms from receiving an instruction to ACK transmission, within 200 ms from receiving an instruction to reflection completion notification transmission (However, the setting backup including data transfer and FW update are according to the scale (size / number of users) It is required to follow the regulations of As an example of function sharing, it is possible to use an application except hardware Config, and to use an application on 16 external servers in FIG. 2 without having software or setting data in the ONU or OLT. It can also be realized by unifying commands and defining sequences.

  FIG. 12 is a diagram of the maintenance operation function (2) low speed monitoring and testing. The processing to be configured includes device state monitoring (CPU / memory / power supply / switching), traffic monitoring, alarm monitoring (ONU abnormality, OLT abnormality), and test (loopback). These processes may be composed of basic processes such as alarm notification, log recording, L3 packet generation / processing, and table management. Device status monitoring, traffic monitoring, alarm monitoring, and testing may be implemented by combining basic processing with equivalent processing. Also, the order may be reversed.

  In this main function, it is required that the latency be within 100 ms, etc. As an example of function sharing, only notification / display IF is an application, and items requiring monitoring (CPU load, memory usage, power status, power consumption, Ethernet (registered trademark) link status, etc.) are device dependent parts. It is also possible to use an application that cuts off IF such as reading of notification from the device dependent unit, NW (network) transmission of notification, writing to a file and the like.

FIG. 13 is a diagram of the maintenance operation function (3) high-speed monitoring and control. As the processing to be configured, there is exchange of monitoring and control which requires high speed (sleep instruction / response, λ setting switching instruction / response, etc.). As a means of this processing, a Physical Layer OAM (PLOAM) message and a bit indication (Embedded OAM) in the header are used. These processes may be composed of basic processes such as PLOAM processing, Embedded OAM processing, communication with a power saving function unit, communication with a protection function unit, and communication with a PON access control unit. The exchange of monitoring and control requiring high speed may be realized by combining the basic processes with equivalent processes. Also, the order may be reversed.
This main function is required to comply with the regulations such as PLOAM processing within 750 microseconds.

  FIG. 14 is a diagram of a PON multicast function. As processing to configure, there are identification / distribution of a multicast stream, MLD proxy / snooping, ONU filter setting, transition of setting between wavelengths. These processes may include basic processes such as L2 identification / distribution, L3 packet processing (preferably including IPv6 Parse), L3 packet generation, table management, and communication with the OMCI function. The multicast stream identification / distribution, MLD proxy / snooping, ONU filter setting, and inter-wavelength setting transition may be realized by combining basic processing with equivalent processing. Also, the order may be reversed. In this main function, when processing 10 Gbit / s / λ and 2.5 Gbit / s / λ for each wavelength for identification / distribution, each of 10 Gbit / s / λ and 2.5 Gbit / s / λ or more If the stream processing processes a plurality of wavelengths, it is required that the plurality of wavelengths conform to a rule that the packet processing has a Zapping performance (JOIN latency) of 1.5 seconds or less on average. As an example of function allocation, identification / allocation of a multicast (MC) stream can be performed by software if it has a high-speed processing capability, but hardware + config is desirable. In addition, since the application system and ONU setting for uplink are loose in frequency and delay constraints, they are applications.

  FIG. 15 is a diagram of a power saving control function. The processing to be configured includes sleep proxy / traffic monitor, ONU wavelength setting, and inter-wavelength setting transition. These processes may include basic processes such as L3 packet processing (preferably including IPv6 Parse), L3 packet generation, table management, OSU power saving SD (State Diagram), and communication with the OMCI function. The sleep proxy / traffic monitor, ONU wavelength setting, and inter-wavelength setting transition may be realized by combining basic processing with equivalent processing. Also, the order may be reversed. In this main function, it is required that the transmission / reception rise time (receiver / transmitter) be 10 ms / 5 ms, and that the rise time (LC / OSU / OLT) 100 ms / 1 s / 10 s, etc. be followed. As an example of function sharing, PS (Power Save) application, and depending on the signal, proxy processing can also be an application. The power saving control state transition management (driver unit) requires a speed but may be an application. The traffic monitor can also be a config only app.

  FIG. 16 is a diagram of the frequency / time synchronization function. The OLT subordinately synchronizes its real-time clock (RTC) to, for example, a higher-level device by SyncE (Synchronous Ethernet) (for frequency synchronization) and IEEE 1588v2 (time synchronization). Furthermore, the OMCI is used to notify the ONU of the correspondence between the super frame counter (SFC) of the PON and the absolute time (ToD: Time of Day) information. These processes may be configured by holding a real time clock which is a basic process, and the like. An equivalent process may be realized by a combination of basic processes. Also, the order may be reversed.

  In this main function, frequency synchronization accuracy +/- 50 ppb (LTE FDD, same TDD), time synchronization accuracy +/- 1 to 1.5 us (LTE TDD small cell), +/- 1 us (G. 987.3) It is required to follow the regulations of As an example of function sharing, the real-time clock itself is a device dependent unit, and for example, the time setting calculation to the upper device may be an application (it may be a device dependent unit according to accuracy).

  FIG. 17 is a diagram of a protection function. As processing to configure, redundant switching (CT, SW, NNI, CONT, PON (Type A, B, C)) is provided. These processes may be configured from basic processes such as redundant path setting, switching trigger detection, switching notification transmission / reception, switching processing, and the like. An equivalent process may be realized by a combination of basic processes. Also, the order may be reversed. In this main function, forced switching is required to follow the rule such as 50 ms or less. As an example of function sharing, it is also possible to use an application excluding hardware switching trigger detection and switching processing such as failure detection. In the case where an instruction to (or from) the EMS side is made at the time of switching trigger detection without setting a redundant path in advance is device-dependent or the like.

  The eight main functions may be provided as needed. For example, only the PON main signal processing function, the PON access control function, the L2 main signal processing function, and the maintenance operation function may be provided, and other functions are provided. May be

  An example of the software implementation of the main 8 functions is shown in FIG. FIG. 18 shows an example of the function group and whether or not software can be used. The following shows an example of whether or not software can be implemented for each of the eight functions in the function group.

  Specifically, the PON main signal processing function of the first function group includes functions such as PHY adaptation, framing, and service adaptation, and it is difficult to realize software.

  The PON access control function of the second function group includes ONU registration / authentication control, ONU registration / authentication application, DBA control, DBA application, DWA control (λ setting switching), DWA application (wavelength protection and wavelength It includes functions such as sleep), etc., and the ONU registration / authentication control application, the DBA control application, and the application of the DWA application (including wavelength protection and wavelength sleep) can be implemented as software. Also, as an effect (differentiation factor) of the extensibility of each function, the ONU registration / authentication application has the concealment of the authentication method, the DBA application has the flexible QoS, and the DWA application (including wavelength protection and wavelength sleep) Softening is desirable because it has flexible QoS.

  The L2 main signal processing function of the third function group includes functions such as MAC learning, VLAN control, path control, band control, priority control, delay control, Copy, etc., and is hard to be softened.

  The maintenance operation function of the fourth function group includes device setting / management, setting / management application, low speed monitoring / testing, low speed monitoring application (ONU / OLT monitoring: EMS), low speed monitoring application (OMCI), It consists of functions such as high-speed monitoring and control, high-speed monitoring application, setting and management application, low-speed monitoring (OMCI) application, and high-speed monitoring application can be software, and low-speed monitoring application (ONU / OLT monitoring) depends on the situation . In addition, as an effect (differentiation factor) of the extensibility of each function, the setting and management application has an effect of radically reducing Opex by coordinating with the controller, and the low speed monitoring application (ONU / OLT monitoring: EMS) By coordinating with EMS, it has the effect of drastic Opex reduction.

  The multicast (frame processing) of the fifth function group consists of MLD proxy and multicast (frame processing) functions, and the application of the MLD proxy can be softened.

  The power saving control function (access control) of the sixth function group includes functions of power saving control and a power saving application, and the power saving application can be implemented as software. Also, as an effect of the extensibility of each function (differentiation factor), the power saving application has a flexible effect of QoS.

  The frequency / time synchronization function of the seventh function group consists of the frequency / time synchronization function and is difficult to soften. The protection function of the eighth function group includes functions of protection control and a protection algorithm (application), and the protection algorithm (application) can be softened. Also, the protection algorithm has the effect of the extensibility of each function (differentiation factor).

  The evaluation as to whether or not the software of each function in FIG. 18 is an example is based on the premise that the processing capacity of the OLT assumed in 2018 and the application of the soft switch are not assumed. It may be suitably changed on the assumption of application of assumed processing capacity and soft switch. Further, the internal configuration of each function may be another configuration as long as the same function can be realized.

  As shown in FIG. 18, the algorithm included in the main eight functions is the main softened area. A function in the software domain is a device-independent application on the device-independent API 21. For example, the algorithms in the ONU registration / authentication function, the DWBA function, the setting / management / monitoring control function, and the power saving control function contributing to the differentiated service are treated as extended functions in the device-independent application. The MLD proxy app includes a multicast function.

  The extension function is an extension function according to the importance of updating frequency of the function, realization of the original specification, etc. in the application. It is preferable to use middleware other than the basic function or device-independent application, device-dependent software, or hardware that has a low update frequency or a low requirement for implementation such as proprietary specifications. In particular, it is preferable to leave the limited functions that come from the processing power of software as hardware. For example, a function that contributes to service differentiation or a high frequency of renewal such as DBA to improve priority processing of main signal and line utilization efficiency, management closely related to the operator's business flow and requiring individual specifications for each operator Change from control function to extended function.

  An example of architecture based on FIG. 18 is shown in FIG. In the optical access system according to FIG. Comply with the 989 series. The connection relationship shown below is an example, and there may be a connection with no intervening connection, or a part of a plurality of connection relationships may be connected, or any other connection may be used. . The same applies to the other explanations. In EMS (Element Management System) functioning as a controller, a low speed monitoring application (EMS-IF) and a setting / management application are arranged via an IF conversion application. The low speed monitoring application (EMS-IF) connected with the L2 (layer 2) function is connected with the NE controller, and the setting / management application is connected with the NE management. The low speed monitoring application (OMCI), the MLD proxy application and the power saving application are connected to the L2 function, respectively.

  The protection application is connected to the PLOAM Engine and the Embedded OAM Engine. The power saving app is connected to the PLOAM Engine via OMCI and a high-speed monitoring app. The ONU registration authentication and DWBA application are connected to the PLOAM Engine, and the DBA application is connected to the Embedded OAM Engine. The power saving application may be operated between the protection application, the ONU registration authentication, the DWBA application, and the DBA application, respectively.

  FIG. 20 shows an example of basic capability deployment on the device. In the optical access system according to FIG. 20, an example in which the functions are distributed and arranged on a plurality of CPUs on the CPU version is shown. Here, the CPU version is an example in which the CPU of the CPU version is divided into three groups of CONT (control version, controller, control unit, etc.) direction, OSU direction, and SW direction. Each of the three groups of CPUs may be a single CPU, or may be composed of a plurality of CPUs, or a GPU (Graphics Processing Unit), an FPGA (Field Programmable Gate Array), or a DSP (Digigal Signal Processor) Or an arithmetic function such as an application specific integrated circuit (ASIC) or the like.

  The plurality of CPUs on the CPU version may be a single CPU. With a single CPU, overhead processing for inter-CPU communication is reduced. Also, instead of centralized processing in the CPU version, each group may be distributed and arranged in three PKGs (packages, versions) (Cont version, OSU, SW). The CONT version connected to the device setting IF and the EMS-IF performs data input / output via each application group divided into three groups of CONT orientation, OSU orientation, and SW orientation, as shown in FIG. Each application in the direction was a low speed monitoring application (OMCI), a low speed monitoring application (EMS-IF), and a setting management application. In addition, each application for SW was MLD proxy application. Each application for OSU was a power saving application, a protection application, a high-speed monitoring application, a DBA application, a DWA application, and an ONU registration authentication application. These functions and function groups are examples, and may be rearranged or removed and added / reused.

  Middleware is installed in each OSU and switch. The middleware may be centrally installed in any of the functions and hardware as long as it can ensure the connectivity with each other. Each OSU comprises an optical transceiver (λ Card in the figure) of a predetermined wavelength. A control version (CONT. In the figure), which is a control unit in the OLT, controls each application and hardware directed to the CONT. The CONT, OSU, and SW applications are connected to each other so as to input and output data via the middleware or without using the middleware.

  Each application is an example processed by the CPU on the CPU package. In the figure, each application is processing for the control version (CONT. In the figure) which is a control unit in the OLT, processing for the OSU package (OSU in the figure) including the optical transceiver (λCard in the figure), OSU and upper side It is classified into 3 groups for SW package that exchanges data with devices of Power saving application, protection application, high speed monitoring application, DBA application, DWA application, ONU registration authentication application as OSU group, MLD proxy application as SW group, low speed monitoring application (OMCI) as CONT group, low speed monitoring application (EMS- IF), setting management application. Furthermore, although the centralized arrangement in the CPU version is assumed, the classified applications of each group may be distributed to each PKG (Cont, OSU, SW).

  Also, regardless of the above classification, it may be arranged on any one of Cont, OSU, SW or a plurality of combinations thereof. Further, the device setting IF in the drawing may be a part of the EMS-IF, or may be equivalent to the API 25 of FIG. Although the processing of the application is performed on the CPU, part or all of the processing may be performed on an alternative having a processing function, for example, a processor other than the CPU, a processor such as NPU or DSP, or an FPGA. The same applies to the other embodiments of the present application.

  FIG. 21 shows an example in which an application is arranged on a server or the like instead of the CPU package. The application processes on a server or the like, transmits the processing result on a transmission line as a format that can be transmitted on a transmission line such as an Ethernet frame, and then arrives at the OLT. Here, as a format that can be transmitted through the transmission line, transmissions such as frames other than Ethernet frames and TDM may be used, though the conversion unit (CONV. In the figure) is used, but the OSU, SW, or λ card converts If it is possible to receive the processing result of the application without going through the machine, no converter is necessary. The server or the like may be equivalent to the external server 16 of FIG. 2 or may be equivalent to the proxy unit 15.

  FIG. 22 shows an example of processing other than the application and the application. In the figure, an example of the processing with the basic function and the processing with the unique function and the processing with the vendor-dependent portion of the OSUMAC is shown in the figure, but the present invention is not limited to this classification. The CPU of this figure may be the CPU package of FIG. 20, the server of FIG. Although OSUMAC assumes the LSI for exclusive use which performs OSU processing, if equivalent processing is possible, you may use general purpose LSI.

  In the optical access system according to FIG. 22, the CPU, as a first group, performs fault management of the maintenance operation function and GTC / PMD Config of the maintenance operation function, ONU Activation / Deactivation of the PON access processing function, and the DBA of the PON access processing function It has λ (wavelength) allocation change of PON access processing function and has Sleep and protection function of power saving control function as the second group, Service Management of maintenance operation function as the third group and maintenance operation The fourth group consists of maintenance management function Fault Management and maintenance operation function Performance Management and multicast function MLD. And with

The OSU MAC has Framing of the PON main signal processing function, Security such as encoding / decoding of encryption of the PON main signal processing function, FEC function of the PON main signal processing function, and frequency / time synchronization function. Also, the OSU MAC may perform data processing in the order of the XGEM Framer, the encryption, the XGTC Framer, the FEC, the PHY Framer, the SP conversion, and the PMD. The encryption may be performed by the Security function of the PON main signal processing function, the FEC may be performed by the PON main signal processing function (FEC), and the Framer Sync located upstream of the PHY Framer may be performed by the frequency / time synchronization function.

  FIG. 23 shows processing of main eight function applications and G. This is the correspondence with the 989.3 functional diagram. As shown in FIG. 23, each application uses a power saving application, a protection application, a high-speed monitoring application, a DBA application, a DWA application, and an ONU registration authentication application. In TWDM TC Layer, (1) has PHY Burst Timing and Profile Control, and (2) has Upstream Bandwidth Management (Mgmt.) DBA Control and FS Frame / Burst functions as PLOAM Partition function, Embedded Header Field function and XGEM partition It has functions, and in (3) it has User Data Adapter, OMCI Adapter and XGEM Engine.

  The User Data Client and the OMCI Client are connected to the User Data Adapter and the OMCI Adapter, respectively. User Data Adapter is a TWDM PMD via Security key Management (mgmt.), ONU Power Management (mgmt.), TWDM Channel Management (mgmt.) And TWDM TC Functions with Protection, PLOAM Proccessor, and AMCC PHY. The AMCC PMC is connected to the AMCC PMC among the AMCC PMC and the conventional TWDM PMD that the Layer has.

  FIG. 24 shows an example in which, in addition to user data, PLOAM and OMCI also receive corresponding ones from 4 or 5 or 6 in FIG. 2 via SW. As shown in FIG. 24, each application uses a power saving application, a protection application, a high-speed monitoring application, a DBA application, a DWA application, and an ONU registration authentication application. In TWDM TC Layer, (1) has PHY burst timing and profile control, and (2) has Upstream Bandwidth Management (mgmt.) DBA Control and FS Frame / Burst as PLOAM Partition, Embedded Header Fields and XGEM Partition. In (3), it has User Data Adapter, OMCI Adapter and XGEM Engine.

The User Data Adapter performs TWDM via Security Key Management (mgmt.), ONU Power Management (mgmt.), TWDM Channel Management (mgmt.), TWDM TC Functions with Protection Control, PLOAM Proccessor, and AMCC PHY. Among the AMCC PMCs and Conventional TWDM PMDs included in the PMD layer, they are connected to the AMCC PMC. In addition, between PLOAM Proccessor and AMCC PHY shown in FIG. 24, between PLOAM Partition and PLOAM Proccessor of FS Frame / Burst, and between Embedded Header Fields and TWDM TC Functions of FS Frame / Burst are connected via SW. .

  In the examples of FIGS. 1 and 3, the software domain is the basic function, management / control agent, extended functions A, B, C, and middleware, but the software domain is service adaptation (encryption, fragment processing , GEM (GPON Encapsulation Method) framing) / XGEM (XGPON Encapsulation Method) framing) X, PHY adaptation FEC, scrambling, synchronous block generation / extraction, GTC (GPON Transmission Convergence) framing, PHY framing, SP conversion The coding scheme may also be targeted.

  An implementation example of the software implementation function of the architecture and an example of function deployment corresponding to the hardware will be described. The function deployment includes, for example, a software function on a network device or an external server.

  An OLT comprising a plurality of OSUs, switches, an information processing unit, and a control unit is assumed. Each OSU comprises a different transceiver for each wavelength. In this case, the middleware is mounted on each OSU and switch, and the software domain such as the device independent application is mounted on the information processing unit.

  The information processing unit, that is, the CPU executes the device-independent application. The device independent application includes an extension function for the OSU, an extension function for the switch, and an extension function for the control unit. The extended functions for the OSU are, for example, a power saving application, a protection application, a DBA application, and an ONU registration authentication application. The extension function for the switch is, for example, an MLD proxy application. The extended functions for the control unit are, for example, a low speed monitoring application (OMCI), a low speed monitoring application (EMS (for example, OSS (Operation Support System))-IF: (InterFace), and a setting / management application.

  G. In the case of 989.3, for example, it becomes as shown in FIGS.

  In the case of the DBA application, the middleware shown in FIGS. 1 and 3 or the basic functions shown in FIGS. 4 and 5 operate the Embedded OAM Engine, which is hardware of the TC layer. Then, the transmission / reception unit, which is the hardware of the PMD layer, receives according to the DBA application. When the transmitting and receiving unit receives even an uplink signal which does not comply with the DBA, the DBA application may not be followed.

  The information processing unit is not limited to these software functions, and may have other software functions. The hardware is not limited to the transmission / reception unit, the OSU, the switch, the control unit, and the information processing unit. For example, the information processing unit may be included in the transmission / reception unit, the OSU, the switch, and the control unit.

  In addition, as shown in the drawings of configuration examples described later, the network-network interface (NNI) side of the switch may be provided with a proxy unit or an external server that processes signals input to and output from the switch. The external server may be an information processing function called a so-called cloud such as a data center including a plurality of devices.

  Each function may be appropriately arranged in accordance with the demand for processing capacity and processing delay. In addition, the OSU may include a switch (switch unit 12 or switch unit 13 described later), and the switch may include a switch (switch unit 12 in the case of including switch unit 13 described later) separately from the switch. It is desirable that the functions of the switches be appropriately shared according to the processing capability of the switches without overlapping between the switch unit 12 and the switch unit 13, but they may be overlapped.

  The location for deploying the software function may be located not only in the information processing unit but also in a plurality of locations where arithmetic processing can be performed. For example, the place to deploy the software function is other than the transmission / reception unit, the switch of the OSU, the switch of the OSU, the control unit of the OLT, the switch of the OLT, the information processing unit of the OLT, the switch of the OLT, the control unit and the information processing unit, The NNI side of the switch may be either a proxy unit that processes signals input to or output from the switch or a processing device such as an external server.

  Also, the arrangement of the software function may be for each software function or may be part of a software function obtained by dividing a single software function. For example, components related to the transmitting and receiving unit may be other than the transmitting and receiving unit, for example, switches of the OSU, switches other than the transmitting and receiving unit of the OSU, switches of the OLT, control units of the OLT, information processing units of the OLT, others of the OLT, It may be deployed in a combination of a plurality of deployment locations such as a proxy unit located on the main signal route outside the OLT, an external server, or the like. Things related to PON termination other than PON termination processing deployment point, for example, transmission / reception unit of OSU, switch of OSU, switch other than transmission / reception unit of OSU but other than switch, switch of OLT, control unit of OLT, information processing unit of OLT Other than that of the OLT, it may be deployed in a combination of a plurality of deployment locations such as a proxy unit located outside the OLT and on the main signal path, an external server, or the like.

  Components related to the ONU switch other than the ONU switch, for example, the transmitting / receiving unit, other than the transmitting / receiving unit of the OSU and other than the switch, the switch of the OLT, the control unit of the OLT, the information processing unit of the OLT, other than that of the OLT, the OLT May be deployed in any combination of multiple proxy locations such as a proxy unit, an external server, etc., which is on the path of the main signal outside. Components related to the switch of the OLT are other than the switch of the OLT, for example, the transmitting / receiving unit, the switch of the OSU, other than the transmitting / receiving unit of the OSU and other than the switch, the control unit of the OLT, the information processing unit of the OLT, other than that of the OLT, the OLT May be deployed in any combination of multiple proxy locations such as a proxy unit, an external server, etc., which is on the path of the main signal outside.

  In addition, the location where the software function is deployed may be changed as appropriate according to the deployment status of the extended function, the computing capacity of the computeable location, the computing load, the power consumption, and the like.

  The function of dynamic band allocation (DBA), which is a function of the PON access control function, is provided as an example of dividing the function into the execution part and the instruction part and processing the divided part with another device or software processing. Show. Here, in the configurations shown in FIGS. 1 and 3, the device dependent unit functions as the execution unit and the device independent application is the instruction unit, but both may be device independent applications due to function deployment, and both devices It may be a dependent part. As an example where both are device-independent applications, for example, an execution unit of a function such as DBA processing is provided in an information processing unit such as a processor provided in a weak transceiver, and an instruction unit is provided in other places having strong information processing capability This is a case where the processor is provided in the information processing unit, for example, an OSU, etc., and interprocessor communication between devices and interdevice communication work as middleware. When both are provided in the device dependent part, the DBA function may be compiled as a part of firmware etc. as in the example on the left.

  The execution unit repeats the fixed processing, and when the instruction unit does not make the processing result of the execution unit ideal, the correction is performed by the processing of the instruction unit or correction is instructed by instructing the execution unit, and the processing is ideal. Get close. As a thing suitable for such functional processing, DBA, DWA, DWBA, main signal processing, etc. may be mentioned. Alternatively, the executing unit provisionally responds, oversees the definition of the response time, and makes a true response in the instructing unit. Authentication, switching, and the like are suitable for such functional processing. This example of DBA corresponds to the former correction, and can be applied similarly to DWA and DWBA.

The following description will be made on the premise of guarantee assignment, non-guaranteed assignment, and best effort assignment in the case of loose provisions such as delay variation and maximum delay, but in the case of strict assignment of fixed assignment and delay, assignment will be made according to the provisions. In addition, it is desirable to exchange profiles etc., clarify the IFs and parameters to be used and their ranges and continue the exchange, and to exchange the configuration of the device dependent part, the execution part and the instruction part and the exchange of the next execution part and the instruction part. It is desirable to perform IF conversion and parameter conversion according to the required delay time, bandwidth, and whether the communication line is occupied or not.

  The implementation unit continues allocation while switching a predetermined band or a plurality of predetermined bands to the same destination, or switching a predetermined band setting or a predetermined band setting. The instruction unit detects a predetermined operation of the execution unit, and performs DBA according to the difference between the detection result and the desired assignment. The predetermined operation is, for example, assignment or assignment result or assignment history or data conduction or continuity history or request or request history accompanying assignment. For example, the DBA instructs the implementing unit to instruct a predetermined bandwidth, or instructs assignment suppression or priority assignment to a part of the assignment target, or instructs to change a bandwidth setting, or It indicates the priority order or instructs switching of a predetermined band.

  The predetermined band is, on the average, fixed band setting for each allocation target (for example, ONU or queue of ONU, etc.) as a lower limit, maximum band setting as an upper limit, and allocation history of a predetermined period approaches a desired band Set to

  It is desirable that the predetermined period be longer than the time required for the implementation unit to change the predetermined band in response to the instruction from the instruction unit. For example, the time is several to dozens times, which is the time required for multiple changes. In addition, it is desirable that the time be such that the user does not feel the difference from the desired band. For example, it is desirable that the time unit for measuring the bandwidth be, for example, 1 second or less.

  The assignment history of the predetermined period is a history of an exponential average, a moving average, an average in the form of resetting the history at predetermined intervals, and other statistical processing.

  The allocation or assignment result of the execution unit is a report from the execution unit or measurement in any place or holding information for reporting to the upper system or history of past instructions in OAM or backboard or internal wiring or main signal Input from the history of instructions held in the input or instruction unit via a wiring, a dedicated wiring, an operation system such as EMS, or a route such as the Cont version. The history may be integrated other than the instruction unit.

  Data conduction or conduction history is reported from the operation department or measured at any part or held in the upper system for holding information for reporting to the internal wiring, backboard, OAM, main signal wiring, dedicated wiring, operation system, etc. Input via a route such as the Cont version. The history may be integrated other than the instruction unit.

  The request or request history is terminated directly at the instruction unit with a declaration of the ONU or a copy of the declaration, and is input or terminated at any point and the internal wiring, backboard, OAM, main signal wiring, dedicated wiring, operation system And use the input or allocation bandwidth via a route such as a link version or the Cont version (a request for the use if there is an unused portion of the allocation, a request for the allocation if there is no unused allocation (for all uses)) Internal wiring, backboard, OAM, main signal line, dedicated wiring, operation system, Cont version, etc. Input from the history of instructions held by the input or instruction unit via the route of The history may be integrated other than the instruction unit.

  The request or request history may predict a future request or a band that should have been allocated but not allocated from the input allocation or allocation history or data continuity or continuity history or allocation result or request or request history. . The prediction may be made by statistical processing such as a linear function or a quadratic function, or the behavior of TCP etc. in consideration of RTT etc. set in consideration of the past request and the result of allocation use and the distance to the server etc. If there is no unused allocation, the guaranteed band setting may be predicted. If there is no unused allocation, the guaranteed band setting may be nonzero or the fixed band setting may be reduced from the guaranteed band setting. A non-guaranteed band is allocated according to the value obtained by subtracting the fixed band setting from the guaranteed band setting or the guaranteed band setting in the allocation object having a nonzero value and no unused allocation or having a requested allocation exceeding the guaranteed band setting If there is no unused allocation or there is no unused allocation or the guaranteed bandwidth setting is exceeded, it may be estimated that the allocation of the best effort bandwidth is apportioned among the allocation targets that are required. Further, prediction may be performed by combining a plurality of prediction methods.

  The desired bandwidth is determined according to a predetermined ratio, up to a bandwidth obtained by adding the bandwidth for detecting the request or predicted value of the request or request or the predicted value of the request to the allocation target with request. It is good for the The predetermined ratio is, for example, a ratio of guaranteed bandwidth setting or guaranteed bandwidth setting minus fixed bandwidth setting. The predetermined band may be set in TRx units such as each wavelength or code or carrier frequency or core line, or an OSU unit or OSU in which TRx such as a plurality of wavelengths or codes or carrier frequencies or core line are bundled. It may be set in the switch unit in the middle, it may be set in the switch unit that bundled multiple TRx or OSU such as multiple wavelength or code or carrier frequency or core wire, and the upper NW (network) band is shared You may set by the allocation object unit to carry out. It is desirable that the desired band has an upper limit of the maximum band setting for each allocation unit as an upper limit, and if there is a total band setting as a bundle of TRx, it is preferable to set that upper limit.

  As a method of bringing the allocation history of the predetermined period closer to the desired band, the difference is divided by a single or a plurality of predetermined periods to an allocation target for which demand or demand has been predicted and the desired band has a low allocation history for the predetermined period. Even if added bandwidth is added up to the maximum bandwidth setting, priority allocation / allocation suppression, bandwidth setting change, allocation order change, allocation bandwidth switching may be performed, and request presence or demand presence predicted and desired presence Even if the bandwidth divided by one or more predetermined periods is added to the allocation target with low allocation history in the predetermined period from the above, priority allocation / allocation suppression, band setting change, allocation order change, allocation band switching It may be set as the guaranteed band setting of the allocation target for the allocation target whose allocation history is lower for a predetermined period with an expectation of request presence or demand and a desired band, or priority allocation / allocation suppression, band setting change , Change assignment order The allocation band may be switched, or an expected target or an expected target and an allocation target having a low allocation history for a predetermined period from a desired band to a non-guaranteed allocation band or best effort band for guarantee band setting of the allocation target Alternatively, the predicted value may be a value obtained by adding the bandwidth apportioned according to the allocation target, or priority allocation / allocation suppression, band setting change, allocation order change, and allocation band switching.

  Priority allocation even if the bandwidth divided by a single or multiple predetermined periods is subtracted as the lower limit from the fixed bandwidth setting as the allocation target with high expectation of request or demand and an assignment history with a high assignment history from the desired band. -Allocation suppression, band setting change, allocation order change, allocation band switching may be performed, or a difference may be made to an allocation target having a high allocation history in a predetermined period from a desired band with a request presence or anticipation as well. Even if the bandwidth divided by one or more predetermined periods is subtracted, priority allocation / allocation suppression, bandwidth setting change, allocation order change, allocation bandwidth switching may be performed, and prediction with request or request presence and Priority assignment / assignment inhibition, bandwidth setting change, assignment order change, assignment bandwidth change may be performed as assignment of guaranteed bandwidth setting or fixed bandwidth setting to an assignment target having a high assignment history in a predetermined period from a desired band Required, or required Non-guaranteed allocation band or best effort band or its estimated value according to the allocation target according to the allocation target to the allocation target with high allocation history of the predetermined period from the expected and desired band to the allocation target having a high allocation history of the predetermined period Also, as a value to which less bandwidth is added, priority assignment / assignment restraint, bandwidth setting change, assignment order change, assignment band switching may be performed, or no assignment or no assignment is predicted. As the guaranteed bandwidth setting or the fixed bandwidth setting, priority assignment / assignment restraint, bandwidth setting change, assignment order change, assignment bandwidth switching may be performed.

  The predetermined band may be in the form of single or plural BWMap, allocation time for each allocation unit such as T-CONT, Alloc-ID, LLID, etc., combination of start time and allocation time, T-CONT, Alloc-ID, LLID etc. Allocation may be performed by a combination of allocation time and allocation order for each allocation unit. Transmission from the instruction unit to the execution unit may be performed by giving an identifier such as a predetermined bit string so as to distinguish from other information, or may be transmitted in the form of Embedded OAM, or OAM It may be encapsulated and exchanged in a frame, an MPCP frame, a predetermined VID, MAC address, TOS / COS, a combination thereof, or a frame or cell that can be identified by VP or VC. The instruction unit has a function of giving an identifier, encapsulation, and communication on a predetermined communication path so that the processing unit can identify it, and the processing unit receives communication on an identifier identification or decapsulation or a predetermined communication channel so that it can be identified. It has a function. The same applies to input / output from the processing unit to the instruction unit, except that the declaration from the ONU is processed so that it can be received except when the instruction unit directly terminates the declaration, and on the route where the declaration is exchanged Prepare for

  In the above description, the instruction of the instruction unit is shown depending on the vendor and the system, but in the first embodiment of the present application, the middleware in the first embodiment and in the second embodiment of the present invention, the device dependent application may be the middleware. The device dependent unit is an instruction to convert the format of the vendor-independent API 21 and convert it through the vendor-dependent API 21 according to the fourth embodiment of the present invention. The instruction unit of the present application instructs in accordance with the vendor-independent API 21. For example, in the case of band allocation, it is instructed in a form independent of a vendor and a method that can be converted into the form of ITU-T system BWMap or the form of transmission permission time and transmission duration for each IEEE LLID. It also conveys provisions such as jitter, bursts, average time of average band, etc. to accommodate multiservice. Although the above description has been made with respect to the DBA, the same applies to the functions constituting the PON access function other than the DBA and the functions other than the PON access function.

  For example, in the case of the L2 function, the device-independent API 21 instructs only switching of the wavelength for exchanging data of the same path, and the path before and after the wavelength switching is performed by the wavelength switching vendor dependent API 21 as its specific processing The tag is encapsulated in common and transmitted between the switch and the ONU, removed from the tag and decapsulated, or the tag is converted between the wavelengths according to a predetermined conversion rule, transmitted between the switch and the ONU, converted, The device-dependent API 23 (in the case of the second embodiment, the device-dependent API 23 is used to operate a part dependent on a vendor or a system so that a path change is predicted or notified to switch or synchronize in advance with a switch and an ONU. Device dependent API 24 via part or all device dependent application, device dependent API 27 in the case of the third embodiment, device dependent API in the case of the fourth embodiment 7 with some or all indicated by device-dependent API 24) via a device-dependent application.

  For example, in the case of the multicast function, the device-independent API 21 instructs only switching of the wavelength for exchanging data of the same path, and filter setting for wavelength switching is performed by the device-dependent API 23 as one of the specific processing. Paths before and after wavelength switching are common filter settings among wavelengths, converted to predetermined filters between wavelengths according to a predetermined conversion rule, predicted or notified of changes, and switched or synchronized in advance by ONU Device-dependent API 23 (in the case of the second embodiment, device-dependent API 23 and a device-dependent API 24 partially or entirely via the device-dependent application in the case of the third embodiment so as to operate the part dependent on the vendor or system) Is a device dependent API 27, in the case of the fourth embodiment, the device dependent API 27 and a part or all of the device dependent API 24 via a device dependent application). To.

  An example in which a true response is performed by the instruction unit is, for example, a case where an external server or the like checks whether the registered ONU is appropriate. First, the execution unit registers the ONU, and makes an inquiry to the instruction unit via the device-dependent API 23 and the device-dependent API 21. If there is communication of ONU-OLT until the response of the inquiry is returned, necessary communication such as health check is continued without transmitting and receiving user data. If it is sufficient to allocate only the bandwidth, the bandwidth is allocated and the data is retained in the OLT. If a response to user data is required, the execution unit or the instruction unit substitutes for it. In the case of a forced switching sequence, there is no response delay by setting the switching time in the executing unit in advance in the instructing unit before the response time by the instructing unit and starting the process by the delay of the response time. Let's do it.

  Hereinafter, the invention according to the present embodiment will be described with reference to FIG. The communication system according to the present embodiment includes at least a transmission / reception unit (TRx) 11, a switch unit (SW) 12, a switch unit (SW) 13, a control unit 14, a proxy unit 15, and an external server 16. Have some. Although FIG. 2 shows a configuration in which transmission and reception units of different wavelengths (λA to λN) are connected to the same switch unit 12, the present embodiment is not limited to this. For example, in addition to the configuration in which transmission / reception units of different wavelengths (λA to λN) are connected to the same switch unit 12, transmission / reception units of the same wavelength may be connected to the same switch unit 12.

  The OLT may include the transmission / reception unit 11 to the control unit 14 or may include an external server 16 in addition to these. In addition, the OSU may be the transmission / reception unit 11 or may include the switch unit (SW) 12 or 13 in addition to this. The communication system configuration (1-1) includes a transmission / reception unit (TRx) 11, a switch unit (SW) 12, a switch unit (SW) 13, a control unit 14, a proxy unit 15, and an external server 16.

Second Embodiment
FIG. 3 shows an example of the architecture of this embodiment. The communication device according to the present embodiment includes a device dependent application under the control of the middleware. The second embodiment is the same as the first embodiment except that the device dependent application is provided. By providing the device dependent application, there is an effect that the configuration of the middleware can be simplified. The middleware and the device dependent application are connected by the device dependent API 23. The device dependent application and the OAM and software are connected by the device dependent API 24, and the device dependent application and the management and control agent are connected by the API 26.

  As shown in FIG. 3, hardware dependent on a standard or a manufacturing vendor dependent as a device dependent unit from the bottom, software of a device dependent unit such as a driver / firmware that drives the hardware, hardware or software of a device dependent unit, etc. A device-dependent application that drives at least a part of the above, middleware that hides the difference between hardware and device-dependent applications, and a general-purpose device-independent application that does not depend on devices.

  The device-independent application is, for example, a control / management agent that receives communication from the EMS, a basic function, and an extended function ABC. However, the device-independent application may or may not include all of these. For example, when the extension function is unnecessary, the extension function ABC may not be present. Also, preferably, extensions can be added or deleted. For example, in the case where, for example, a multicast service and power saving are made to be an expansion function in accordance with a request for service, the expansion function may be added appropriately when it becomes necessary.

  The basic function may be included as part of the extension function or may be substituted by the middleware subordinate. The device-independent application may not include the basic function if the extended function includes the basic function, or the middleware lower part substitutes for the basic function, or a combination thereof. Also, some of the basic functions may be replaced by device-dependent applications under the middleware. The management control agent does not have to be input / output to / from the EMS if it is automatically set in accordance with the presetting without receiving communication from the EMS. Furthermore, when the management setting function is not provided by the management control agent but is provided by another device-independent application, a basic function, or a device dependent unit, the management control agent may not be provided. Conversely, you may directly input and output EMS and each function independent application. If the lower middleware substitutes all of the basic functions, the device-independent application has an architecture without the basic functions.

  The device dependent application is directly input / output from the management / control agent, but may be via middleware, may be input / output only with either of the two, or may be directly input / output from / to the EMS . The management / control agent may not be provided in the case where the device-dependent application is managed and controlled via the middleware automatically according to settings in advance without receiving communication from the EMS.

  The device independent application inputs / outputs at least the hardware or software of the device dependent unit via the middleware. Device-independent applications input and output mutually via middleware as needed. In particular, when performing control and management according to the input and output from the EMS, the device-independent application inputs and outputs from the control and management agent that receives communication from the EMS.

  The NE management / control unit inputs / outputs management / control agent and NE management / control information via the middleware. The NE management and control unit may directly exchange NE management and control information with the EMS without passing through the middleware. The device dependent application inputs / outputs management / control agent and NE management / control information. Device dependent applications may interact directly with the EMS without the intervention of a management and control agent.

  The device-independent application is an application that operates regardless of the device generation regardless of the device vendor as in the architecture shown in FIG. 1, but as the application of the extended function, it is via the device-independent API 21 In addition, an application for driving a function provided to a part of devices or an application for driving a function provided only for a device of a generation may be included.

  The management and control agent inputs and outputs EMS, middleware and device dependent applications. The middleware inputs and outputs the NE management and control unit and the NE management and control information. The NE management and control unit may directly exchange NE management and control information with the EMS without passing through the middleware. The middleware inputs and outputs through the device-independent application and the device-independent API 21, and inputs and outputs through the device-dependent OAM, driver, firmware, hardware, and the device-independent API 21.

  The middleware inputs as it is or in a predetermined format as in the architecture shown in FIG.

  Similar to the architecture shown in FIG. 1, it is desirable that the device-independent API 21 be provided with middleware in advance assuming an extended function to be added later, but if necessary, the device-dependent API 23 and other device-independent applications You may add / delete in the form which suppresses modification of.

  The configuration in FIG. 2 may be an ONU as in the architecture shown in FIG. 1, or may be either an OLT or ONU of a PON compliant with ITU-T recommendations other than TWDM-PON, It may be a PON conforming to the IEEE standard such as GE-PON, 10GE-PON, etc. The TC layer and the PMD layer are the same if they are replaced with the corresponding layers.

(Embodiment 3)
FIG. 4 shows an example of an architecture according to the present embodiment. In the present embodiment, the basic function communicates with the hardware and the extension function in place of the middleware described in the first embodiment. The other device-independent applications are the same as in the first embodiment. As compared with the first embodiment, it is not necessary to create for each different device at least one of a standard, generation, method, system, device type, and manufacturing vendor that complies with middleware having the device dependent API 24. More functions can be generalized and ported easily, connectivity can be easily verified, and the function of the device can be made robust. The basic function and each extension function are connected by the device independent API 22, and the basic function and the device dependent part are connected by the device independent API 27.

  As shown in the figure, it comprises an apparatus dependent part and an apparatus independent application from the bottom. The device dependent part is composed of software such as a driver or firmware for driving hardware or hardware dependent on a compliant standard, a device manufacturing vendor or the like. The driver or the like hides the difference between the device dependent parts. The device-independent application is connected to the device-dependent unit via the porting IF (device-independent API 27) and a driver that hides the difference between the hardware and software of the device-dependent unit. A general-purpose device-independent application that does not depend on devices is provided. The device independent application inputs / outputs data to / from hardware or device dependent software via a driver that hides the difference between hardware and device dependent software.

  The basic function in the device-independent application exchanges the device dependent part such as hardware with the extension function instead of the middleware. The basic function may include a control / management agent equivalent to receive communication from the EMS, or may have a control / management agent as an extended function. Basic functions are input / output via other device-independent application and device-independent API 22 and input / output via OAM, driver, firmware, hardware and device-independent API 27 of device-dependent part and device-dependent portion driver Do.

  The basic functions are input as they are or in a predetermined format as in the middleware shown in FIG. For example, in the case of a device-independent application, it is converted to the format of the device-independent API 22 of the format to be input to each, and in the case of an OAM or driver or firmware or hardware of the device dependent portion It converts into the form of the dependent API 27 or terminates and performs predetermined processing and inputs. Unnecessary input information is deleted at each input destination at the time of input, and if there is insufficient information, it is desirable to collect and supplement via other device independent API 22 or device independent API 27 May be broadcast or multicast and broadcast to related applications and the like.

  The device-independent application is, for example, a basic function or an extended function ABC. However, the device-independent application may or may not include all of these. For example, when the extension function is unnecessary, the extension function ABC may not be present. In addition, it is preferable that the extension functions can be added, deleted, replaced, or changed independently without affecting other functions. For example, in the case where the multicast service and power saving are expanded according to the request on the service, for example, the extended function is appropriately added when it becomes necessary, and deleted when it is no longer necessary according to the change It may be replaced or changed.

  In the case of automatically setting according to the setting in advance without receiving the communication from the EMS, the basic function may not include the management control agent or the management control agent equivalent. The extension function of the device-independent application inputs / outputs via at least the device-independent API 22 via the basic function. Device-independent applications input and output mutually through basic functions as needed. In particular, when the control / management agent that receives communication from the EMS is an extended function, it inputs / outputs from / to the control / management agent. The management / control agent may input / output NE management / control (not shown) and NE management / control information, or NE management / control (not shown) and EMS may be directly as they are or converted without input / output. May be exchanged via

  The device independent application is an application that operates regardless of the device generation regardless of the device vendor as in the architecture shown in FIG. 1, but as the application of the extended function, via the device independent API 22 An application for driving a function provided in a part of devices, or an application for driving a function provided only in a device of a part of generations may be included.

  It is desirable that the device-independent API 22 prepare for the basic functions in advance, assuming an extended function to be added later, but if necessary, suppress modification of the device-independent APIs 22 and 27 and other device-independent applications You may add or delete in the form.

  As in the architecture shown in FIG. 1, the configuration of FIG. 3 may be an ONU, or may be either an OLT or ONU of a PON compliant with ITU-T recommendations other than TWDM-PON, It may be a PON conforming to the IEEE standard such as GE-PON, 10GE-PON, etc. The TC layer and the PMD layer are the same if they are replaced with the corresponding layers.

  A comparison of this embodiment with the prior art is shown in FIG. The left of the figure is the prior art and the right is the third embodiment. In the conventional example, the carrier / service extension function (unique function) is an individual implementation in which the interface with the basic system is unclear. For this reason, the firmware / software is different for each device, and when it is attempted to delete / add / replace the carrier / service-specific extension function, it is necessary to remake the firmware / software for each system. Further, in the present embodiment, by providing an extension interface (IF) for implementing the carrier / service-specific extended function in the basic system (mainly the basic functions therein), the carrier / service-specific extended function (original function) Can be easily deleted / added / replaced. Furthermore, by providing a porting interface (IF) concealing the device dependency between the basic function and the device dependent part in the basic system, the basic function and the carrier / service-specific extended function thereon (unique function) are different. It becomes possible to commonize between the crisis.

(Embodiment 4)
FIG. 5 shows an example of an architecture according to the present embodiment. The difference between the present embodiment and the third embodiment is that there is a device dependent application under the basic function. By providing the device-dependent application, the configuration of the basic function can be simplified.

The basic function and the device dependent application are connected by the device independent API 27, and the device dependent application and the device dependent part are connected by the device dependent API 24.

  The basic functions in the device-independent application communicate with the hardware and the extension functions instead of the middleware. The basic function may include a control / management agent equivalent to receive communication from the EMS, or may have a control / management agent as an extended function. Basic functions are input / output via other device independent application and device independent API 22 (IF for expansion), OAM of device dependent part, driver, firmware, hardware, device dependent API 27 (IF for port) and device Input / output is performed via the device dependent driver or device dependent application and the device dependent API 24 that hide the difference between the dependent portions.

  The basic functions are input as they are or in a predetermined format as in the middleware shown in FIG. For example, if it is another device-independent application, it is converted into the format of device-independent API 22 of the format to be input to each, and if it is an OAM or driver or firmware or hardware of the device dependent part, the format is to be input to each It converts into the format of the device-independent API 27 or terminates and performs predetermined processing and inputs. At the time of input, it is desirable to delete unnecessary input information in each input destination, and if there is insufficient information, collect and supplement via other device-independent APIs 22 and 27 or device-dependent API 24. The input may be broadcasted or multicast and broadcast to the related application or the like.

  The device-independent application is, for example, a basic function or an extended function ABC. However, the device-independent application may or may not include all of these. For example, when the extension function is unnecessary, the extension function ABC may not be present. Also, preferably, the extension functions can be added or deleted or replaced or changed without affecting the other functions independently of each other. For example, in the case where the multicast service or power saving is an extension according to the service requirement, the extension may be added as needed when needed, or deleted when no extension is needed. It may be replaced or changed when it is necessary to change.

  Some of the basic functions may be replaced by device-dependent applications. The device dependent application is directly input / output from the basic function, but may be input / output as it is with the EMS or after the predetermined conversion without passing through the basic function. In the case of automatically setting according to the setting in advance without receiving the communication from the EMS, the basic function may not include the management control agent or the management control agent equivalent. The extension function of the device independent application inputs / outputs via at least the device dependent API 24 via the basic function. Device-independent applications input and output mutually through basic functions as needed. In particular, when the control / management agent that receives communication from the EMS is an extended function, it inputs / outputs from / to the control / management agent. The management / control agent may input / output NE management / control (not shown) and NE management / control information, or NE management / control (not shown) and EMS may be directly as they are or converted without input / output. May be exchanged via

  The device-independent application is an application that operates independently of the device vendor and does not depend on the generation of the device as in the architecture shown in FIG. An application for driving a function provided to a device vendor of a part or an application for driving a function provided only for a device of a part of generations may be included.

  It is desirable that the device-independent API 22 be provided with basic functions in advance, assuming an extended function to be added later, but if necessary, the device-independent API 22, 27 or other device-independent application or device-dependent application The modification of the device dependent API 24 may be added or deleted while suppressing the modification.
