These embodiments are merely examples, 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, the same reference numerals denote the same components.

(Embodiment 1)
In the present embodiment, the PON bridge function other than the Classifier / Modifier function of GEM-ID 機能 VID is transferred to the switch. First, an PON-OPT (Optical Line Terminal) compliant with ITU-T recommendation such as TWDM-PON (Time and Wavelength Division Multiplexing-Passive Optical Network) system will be exemplified.

  Although it is OLT here, it may be ONU, OLT or ONU of PON compliant with ITU-T recommendation other than TWDM-PON, or IEEE such as GE-PON, 10GE-PON, etc. A PON conforming to the standard may be used, and the TC (Transmission Convergence) layer and the PMD (Physical Medium Dependent) layer are the same if they are read as corresponding layers.

(Embodiment 1-1)
In Embodiment 1-1, a configuration used for TWDM-PON will be described. The architectures shown in the architecture examples 1 to 4 are exemplified below, but other architectures may be used, and a function to be softened may be provided as hardware.

(Architecture example 1)
FIG. 1 shows an architecture example 1. The architecture example 1 includes a device-dependent unit that depends on standards and manufacturing vendors that conform from the bottom, middleware that hides the hardware and software differences 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 device-dependent software, OAM, and hardware 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. .

  Which functions are to be device-dependent or device-independent apps is not limited by processing to realize middleware or device-independent apps, for example, updates from software processing capabilities. By proceeding according to the degree of importance, such as the realization of frequency and original specifications, etc., it is possible to easily and flexibly add extended functions (original functions) by device-independent apps, and to provide services in a timely manner. For example, it is recommended that the frequency of renewal such as DBA, which improves the priority processing of the main signal and the use efficiency of the line, or contributes to service differentiation. Furthermore, it is preferable that the device-independent application is selected from those having a small difference in at least one of the standard, generation, method, system, device type, and manufacturing vendor that the device to be shared complies with.

  In order to promote the generalization of the functions of at least one of the compliant standards, generations, systems, systems, equipment types, and manufacturing vendors, it is optimal for at least one of the compliant standards, generations, systems, systems, equipment types, and manufacturing vendors. There is no common interface. The common interface may include unused interfaces and parameters depending on the standard, generation, method, system, device type, and manufacturing vendor that the device-dependent unit conforms to. The middleware configured in FIGS. 1 and 2, the driver of the device dependent unit configured in FIGS. 3 and 4, and at least one of the vendor dependent applications configured in FIGS. 2 and 4 correspond to the device dependent unit. Thus, it is desirable to have a conversion function for conversion and a function for automatic setting corresponding to a lacking interface or parameter.

  In FIG. 1, the device-dependent unit is exemplified by device-dependent software such as hardware, driver, firmware, application, etc. depending on the standard or manufacturing vendor that conforms to the bottom, and the hardware performs MAC (Media Access Control) processing. “Hardware (MAC)” and “physical (PHY)” that performs processes from physical layer processing called PHY (PHYsical sublayer) to processing related to optical transmission and reception are exemplified. In addition to these, the hardware of the device-dependent unit may include a general-purpose server, a layer 2 switch, etc., and conversely, the hardware (MAC) may not be included, or a part of the hardware (PHY) may be included. It does not have to be included.

  For example, it does not include low-level signal processing such as modulation / demodulation signal processing, forward error correction, codec decoding processing, and encryption processing, and may be only an optical-related function, or PCS (Physical Coding Sublayer). It is not necessary to include only the part that encodes data called “PMA”, PMA (Physical Medium Attachment) for serializing data in addition to PCS, and PMD (physical medium attachment) connected to a physical medium. (Physical Medium Dependent) may not be included. If the hardware of the device dependent unit can be directly driven, controlled, operated, and managed from the middleware without using the software of the device dependent unit, the software of the device dependent unit is not necessary.

  The device-independent application includes, for example, a control / management agent that receives communication from an EMS (Element Management System) such as an NE (Network Element) controller, a basic function, and an extended function. However, the device-independent application may not include all of these, or may include more. For example, when the extended function is unnecessary, the extended function is not necessary. The number of extended functions exemplified by three ABCs may be other than three. Further, it is preferable that the extended function can be added, deleted, replaced, or changed independently without unnecessarily affecting other functions. For example, when the extended function is required when the extended function is necessary, for example, when the extended function is required, it may be added, deleted, replaced, or changed according to the service requirements. Good.

  The basic function may be included as a part of the extended function, or may be replaced by a middleware subordinate. When the extended function includes a basic function, when the middleware subordinate replaces the basic function, or a combination thereof, the device-independent application may not include the basic function. When the automatic setting is performed according to the pre-set without receiving the communication from the EMS, the management control agent does not need to input / output the EMS. Further, if the management control agent is not provided with the management control agent and other device-independent applications, basic functions, or device-dependent units are provided, the management control agent may not be provided. Conversely, direct input / output may be performed between the EMS and each device-independent application. Further, the NE management / control unit and its IF need not be provided.

  The basic function may be included as a part of the extended function, or may be replaced by a middleware subordinate. When the extended function includes a basic function, when the middleware subordinate replaces the basic function, or a combination thereof, the device-independent application may not include the basic function. Also, some of the basic functions may be replaced with a device-dependent application under middleware. When the automatic setting is performed according to the pre-set without receiving the communication from the EMS, the management control agent does not need to input / output the EMS. Further, if the management control agent is not provided with the management control agent and other device-independent applications, basic functions, or device-dependent units are provided, the management control agent may not be provided. Conversely, direct input / output may be performed between the EMS and each function-independent application.

  The input / output between the device-independent application and the device-dependent unit is, for example, a DBA (Dynamic Bandwidth Assignment) application and a protection application for the TC layer Embedded OAM Engine, a DWBA application and an ONU registration authentication application for the TC layer PLOAM Engine, The power saving application inputs and outputs information to and from the OMCI (ONU management and control interface) and L2 function, the MLD (Multicast Listener Discover) proxy application and the L2 function, and the low-speed monitoring application (OMCI) exchanges information 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 integrated or a combination of DBA and DWA.

  For example, the management / control agent is an application for a maintenance operation function, and inputs / outputs information to / from the EMS such as the NE controller in the NE management / control unit.

  It should be noted that the device-independent application may have a priority order. For example, the first priority is given the highest priority to the management / control agent. Below the second priority order is, for example, the order of DBA application, DWBA application, power saving application, ONU registration authentication application, MLD proxy application, protection application, and low speed monitoring application (OMCI).

  The device-independent application includes a device vendor, a method, a device type, and a device generation, for example, ITU-TG. TWDM-PON (Time and Wavelength Division Multiplexing-Passive Optical Network) and ITU-T G. XG-PON and ITU-T G. G-PON and ITU-T G. compliant with the 984 series. It is an application that operates regardless of at least one of the differences between BPON conforming to the 983 series, 10GE-PON conforming to IEEE802.3av and IEEE1904.1, and GE-PON conforming to IEEE802.3ah, etc. As an extended function application, an application for driving a function provided for some vendors, methods, types, and generations via a device-independent API 21 and only for devices of some vendors, methods, types, and generations are provided. It may include apps that drive functions.

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

  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 uses the device-independent API 21 format of the input format. If the output destination is an OAM, driver, firmware, or hardware of the device-dependent unit, the middleware converts it to the format of the device-dependent API 23 of the format to be input to each, or terminates and inputs it with a predetermined process. . When inputting, the middleware deletes unnecessary input information at each input destination, and if there is insufficient information, it can collect and supplement other device-independent API 21 and device-dependent API via 23. desirable. In addition, when inputting to the middleware, it may be broadcast or multicast and broadcast to related applications.

  In the figure, the middleware and the device-dependent unit are illustrated as a single unit, but may be configured by a plurality of units. When the hardware of the device-dependent unit includes a plurality of processors, the middleware may input / output using inter-processor communication or the like across the processors and hardware. Device-independent applications and device-dependent device-independent apps may be arranged in a user space on a single processor as an execution program such as DLL (Dynamic Link Library), or users on two or more processors You may arrange | position on space.

  The device-independent application may be arranged in the kernel space after securing an input / output IF such as an application programming interface (API application programming interface), or together with middleware having an IF that can be replaced independently with firmware or the like. It may be arranged, or may be recompiled by being incorporated in firmware or the like. User space and kernel space may be arbitrarily combined for each device-independent application. A device-independent application corresponding to the same function may be implemented in both user space and kernel space. In this case, for example, either one of them may be selected by switching, the both may be processed together, or the actual processing may be performed by only one of them. The same applies to the software of the device dependent unit.

  Desirably, as high-speed processing is required as in main signal processing, DBA processing, and low-layer signal processing, there is a trade-off between scalability and immediacy of replacement, but high-speed processing is expected with less overhead. It is desirable to incorporate in kernel space and firmware. The processor where the device-dependent application is arranged is also the user space or kernel of the processor that performs the actual processing or the processor in the vicinity from the viewpoint of the influence on the other programs due to the restriction of the bus and speed due to the communication between the processors and the occupation of the communication path It is desirable to place it on space or firmware. However, in order to reduce the ability of a processor that performs actual processing or a processor in the vicinity thereof, the communication cost due to communication between processors increases, but processing may be performed by a remote processor.

  The device-independent API 21 is preferably provided in the middleware in advance assuming an extended function to be added later. However, if necessary, the device-independent API 21 may be added in a form that suppresses modification of the device-dependent API 23 and other device-independent applications. It may be deleted.

(Architecture example 2)
FIG. 2 shows an example 2 of the architecture. This architecture includes device-dependent apps under middleware. It is the same as that of the example 1 of an architecture except providing a device dependence application. Architecture example 2 drives at least a part of the hardware and software of the device-dependent unit, hardware and software that drives the hardware depending on the standard of the device-dependent unit that is compliant from the bottom, and hardware that depends on the device manufacturer, and hardware. Device-dependent apps, device-dependent hardware and software, and middleware that conceals the differences between device-dependent apps, and device-independent general-purpose device-independent apps. The middleware and the device-dependent application are connected by a device-dependent API 23. The device dependent application and the OAM, software, and hardware of the device dependent unit are connected by the device dependent API 24, and the device dependent application and the management / control agent are connected by the API 26.

  The device-independent application is, for example, a control / management agent that receives communication from EMS, a basic function, and an extended function ABC. However, as in the architecture examples 1 and 2, the device-independent application may not include all of these, or may include more. Moreover, it is preferable that the extended function can be added, deleted, replaced, or changed without affecting other functions as in the architecture example 1.

  The basic function may be included as a part of each extended function, or may be replaced by a middleware subordinate. When the extended function includes a basic function, when the middleware subordinate replaces the basic function, or a combination thereof, the device-independent application may not include the basic function. Also, some of the basic functions may be replaced with a device-dependent application under middleware. Also, some of the basic functions may be replaced with a device-dependent application under middleware. When the automatic setting is performed according to the pre-set without receiving the communication from the EMS, the management control agent does not need to input / output the EMS. Further, if the management control agent is not provided with the management control agent and other device-independent applications, basic functions, or device-dependent units are provided, the management control agent may not be provided. Conversely, direct input / output may be performed between the EMS and each device-independent application. When middleware subordinates replace all basic functions, the device-independent application has an architecture that does not have basic functions.

  In the architecture example 2, the device-dependent application inputs / outputs via the middleware, but may directly input / output from the management / control agent, may input / output only from either of them, or EMS You may input and output directly. In addition, when the device-dependent application is automatically set according to the pre-set without receiving communication from the EMS, and management / control information can be acquired from the EMS via the middleware, a management / control agent is provided. It does not have to be.

  The device-independent application inputs / outputs at least the hardware or software of the device-dependent unit via the middleware. The device-independent application inputs and outputs to / from each other via middleware as necessary. In particular, the device-independent application performs input / output with a control / management agent that receives communication from the EMS when performing control / management according to input / output from the EMS.

  The NE management / control unit inputs / outputs NE management / control information to / from the management / control agent via the middleware. The NE management / control unit may directly exchange NE management / control information with the EMS without using the middleware. The device-dependent application inputs and outputs management / control agents and NE management / control information. The device-dependent application may directly communicate with the EMS without using the management / control agent.

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

  The middleware is input as it is or in a predetermined format, similarly to the middleware shown in FIG.

  The device-independent API 21 is preferably provided in the middleware in advance assuming an extended function to be added later. However, if necessary, the device-independent API 21 may be added in a form that suppresses modification of the device-dependent API 23 and other device-independent applications. It may be deleted.

(Architecture example 3)
FIG. 3 shows an example 3 of the architecture. In this architecture, instead of the middleware described in the first example of the architecture, the basic function exchanges with the hardware and the extended function. Other device-independent applications are the same as those in architecture example 1. Compared to example 1 of the architecture, it is not necessary to create each device with a different standard, generation, method, system, device type, or manufacturing vendor that complies with middleware with device-dependent API 24. As a result, more functions can be generalized and ported easily, verification of connectivity is easy, and the functions of the device are robust.

  The architecture example 3 includes a device-dependent unit and a device-independent application from the bottom. The device dependent unit is configured by hardware such as a compliant standard or a device manufacturer, or software such as a driver / firmware for driving the hardware. The driver etc. hides the difference of the device dependent part. The device-independent application is connected to the device-dependent unit via a porting IF (device-independent API 27) and a driver that hides the difference between hardware and device-dependent software. A general-purpose device-independent application that does not depend on the device. The device-independent application inputs / outputs data from / to the hardware or device-dependent software via a driver that hides the difference between the hardware and the device-dependent software. The basic function and each extended function are connected by a device independent API 22 (extension IF), and the basic function and the device dependent unit are connected by a device independent API 27.

  The basic functions in the device-independent application communicate with hardware and extended functions instead of middleware. Device-independent apps input and output each other via basic functions as needed. The extended function of the device-independent application is input / output via at least the device-independent API 22 via the basic function. Basic functions are input / output via the device-independent application and the device-independent API 22, and input / output via the device-independent API 27 with the device-dependent OAM, driver, firmware, and hardware.

  The basic function is input as it is or in a predetermined format, like the middleware shown in FIG. For example, if it is another device-independent application, it is converted to the device-independent API 22 format in a format that is input to each device, and if it is a device-dependent OAM, driver, firmware, or hardware, a device that is input in each format It converts into the format of independent API22, or terminates and performs a predetermined process and inputs. At the time of input, unnecessary input information is deleted at each input destination, 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.

  The device-independent application is, for example, a basic function or an extended function ABC. However, the device-independent application may not include all of these, or may include more. For example, when the extended function is unnecessary, the extended function ABC may not be provided. Further, it is preferable that the extended function can be added or deleted independently without affecting other functions and can be independently performed without affecting other functions. For example, when an extension function is required for a multicast service or power saving function, for example, according to service requirements, it is added as needed when the extension function is needed, deleted as needed, and changed according to the change. It may be replaced or changed.

  It is desirable that the device-independent API 22 is provided with basic functions in advance, assuming an extended function to be added later, but if necessary, the device-independent API 22 and 27 and other device-independent applications are suppressed from being modified. You may add and delete in the form.

(Architecture example 4)
FIG. 4 shows an example 4 of the architecture. The difference between this architecture and architecture example 3 is that there is a device-dependent application under the basic function. By providing the device-dependent application, there is an effect that the configuration of the basic function can be simplified. In the example 4 of the architecture, hardware dependent on a standard or device manufacturing vendor that conforms as a device-dependent unit from the bottom, software such as driver / firmware that drives the hardware, device-dependent application that drives at least a part of the device-dependent unit, A general-purpose device-independent application is provided through the porting IF and a driver that conceals the difference between hardware and device-dependent software or through the porting IF and device-dependent application without depending on the device. The basic function and the device-dependent application are connected by a device-independent API 27, and the device-dependent application and the device-dependent unit are connected by a device-dependent API 24.

  The basic functions of the device-independent application communicate with the hardware and extended functions instead of middleware. The basic function may include a control / management agent corresponding to communication from the EMS, or a control / management agent as an extended function. Basic functions are input / output via device-independent applications and device-independent API 22 (extension IF), device-dependent OAM, drivers, firmware, hardware, device-dependent API 27 (porting IF), and device-dependent parts Input / output via a device-dependent API 24 and a device-dependent application driver or device-dependent application that hides the difference between the two.

  The basic function is input as it is or in a predetermined format, like the middleware shown in FIG. Similar to the architecture example 3, the basic function may include a control / management agent corresponding to communication from the EMS, or a control / management agent as an extended function.

  The device-independent application is, for example, a basic function or an extended function ABC. However, the device-independent application may not include all or more than the same as in the architecture example 3. Further, like the architecture example 3, it is preferable that the extended function can be added, deleted, replaced, or changed independently of each other without affecting other functions. Also, some of the basic functions may be replaced with a device-dependent application. The device-dependent application directly inputs / outputs from the basic function. However, the device-dependent application may input / output directly from the EMS or after the predetermined conversion without passing through the basic function.

  As in the architecture shown in FIG. 1, it is desirable that the device-independent APIs 22 and 27 are provided with basic functions in advance, assuming an extended function to be added later, but if necessary, the device-independent APIs 22 and 27 and Other device-independent applications, device-dependent apps, and device-dependent APIs 24 may be added or deleted in a manner that suppresses modification of the device-dependent API 24.

  The configurations in FIGS. 1 to 4 are described on the premise of an PON OLT (Optical Line Terminal) compliant with ITU-T recommendations such as TWDM-PON (Time and Wavelength Division Multiplexi). It may be either PON OLT or ONU compliant with ITU-T recommendations other than TWDM-PON, or PON compliant with IEEE standards such as GE-PON, 10GE-PON, etc. The PMD layer is the same if it is read as the corresponding layer.

  TWDM-PON mainly has 8 functions of 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, and PON main signal processing function. Take the case of having an example. FIG. 6 shows an example of a signal / information flow between the eight main 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, the frequency / time synchronization function, and the 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, respectively.

  Each function will be described with reference to FIGS. FIG. 7 is a diagram of the PON main signal processing function. As processing that constitutes the PON main signal processing function, PHY adaptation, framing, and service adaptation may be provided in the upstream signal processing order (downstream signal processing is reverse). These processes may include basic block generation / extraction, scrambling / descrambling, FEC decoding / encoding, frame generation / separation, GEM encapsulation, fragment processing, and encryption.

  The PHY adaptation may include synchronization block extraction, descrambling, and FEC decoding in the order of upstream signal processing, and FEC encoding, scrambling, and synchronization block generation in the order of downstream signal processing. Equivalent processing may be realized by a combination of basic processing without providing PHY adaptation, framing, and service adaptation processing. Further, the order may be changed. For example, FEC processing may be provided in addition to PHY adaptation.

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

  FIG. 8 is a diagram of the PON access control function. The processing to be configured includes ONU registration / authentication, DBA, and λ setting switching (DWA). These processes may be composed of basic processes. For example, ONU registration / authentication is ranging that configures initial processing, authentication deletion registration, start / stop, DBA receives bandwidth request, traffic measurement, history retention, allocation calculation, allocation processing, setting switching calculation, setting switching processing, setting switching status All or some of the grasps, λ setting switching consists of all or some of bandwidth request reception, traffic measurement, history retention, allocation calculation, allocation processing, setting switching calculation, setting switching processing, and setting switching status monitoring. May be. Equivalent processing may be realized by a combination of basic processing without providing ONU registration / authentication, DBA, and λ setting switching (DWA). Further, the order may be changed.

  In this main function, ONU fast start-up, BWMap within the DBA cycle, non-instantaneous λ setting switching, and the like are required as necessary. As an example of function sharing, as registration / authentication, time-critical ranging processing may be a device-dependent unit, and subsequent authentication and key exchange may be an application. In DBA / λ setting switching, a simple repetitive process may be used as a device dependent unit, and reflection in an ideal state may be used as an application.

  FIG. 9 is a diagram of the L2 main signal processing function. The processes to be configured include MAC learning, VLAN control, path control, bandwidth control, priority control, delay control, and Copy. These processes may be composed of basic processes such as address management, Classifier, Modifier, Policyr / Shaper, Cross Connect, Queue, Scheduler, Copy, and traffic monitor. MAC learning, VLAN control, path control, bandwidth control, priority control, delay control, and copy may not be provided, and equivalent processing may be realized by a combination of basic processing. Further, the order may be changed.

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

  FIG. 10 is a diagram of maintenance operation function (1) device setting / management. The processing to be configured includes ONU / OSU / OLT / SW device settings (manual, batch, automatic, operation trigger), setting backup, FW update, device control (reset), and redundant configuration support. These processes may include basic processes such as CLI-IF, operation IF, general-purpose Config-IF (such as NETCONF / SNMP), and table management. Equivalent processing may be realized by a combination of basic processing without providing device setting, setting backup, FW update, device control, and redundant configuration support. Further, the order may be changed.

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

  FIG. 11 is a diagram of the maintenance operation function (2) low-speed monitoring / testing. The processing to be configured includes device status monitoring (CPU / memory / power supply / switching), traffic monitoring, alarm monitoring (ONU abnormality, OLT abnormality), and test (loopback). These processes may comprise basic processes of alarm notification, log recording, L3 packet generation / processing, and table management. Device status monitoring, traffic monitoring, alarm monitoring, and testing may be realized by combining the same processing with basic processing. Further, the order may be changed.

  In this main function, it is required to comply with regulations such as latency within 100 ms. As an example of function sharing, only the notification / display IF is an application, and items that need to be monitored (CPU load, memory usage, power supply status, power consumption, Ethernet link status, etc.) are device-dependent units An application that cuts off the IF, such as reading a notification from the device-dependent unit, sending a notification NW, or writing to a file, can also be used.

  FIG. 12 is a diagram of the maintenance operation function (3) high-speed monitoring / control. The processing to be configured includes high-speed monitoring / control exchanges (sleep instruction / response, λ setting switching instruction / response, etc.). As a means of this processing, a Physical Layer OAM (PLOAM) message and a bit display (Embedded OAM) in the header are used. These processes may be composed of PLOAM processing, which is basic 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 monitoring / control exchange requiring high speed may be realized by combining the same processing with the basic processing. Further, the order may be changed.

  This main function is required to comply with regulations such as PLOAM processing within 750 microseconds. FIG. 13 is a diagram of the PON multicast function. The processing to be configured includes multicast stream identification / sorting, MLD proxy / snooping, ONU filter setting, and transition between wavelength settings. These processes may include basic processes such as L2 identification / distribution, L3 packet processing (preferably provided with IPv6Parse), L3 packet generation, table management, and communication with the OMCI function. Multicast stream identification / distribution, MLD proxy / snooping, ONU filter setting, and inter-wavelength setting transition may be realized by a combination of basic processes. Further, the order may be changed.

  In this main function, when 10Gbit / s / λ and 2.5Gbit / s / λ processing is performed for each wavelength, the identification / distribution is 10Gbit / s / λ and 2.5Gbit / s / λ or more, respectively. If the stream processing is to process a plurality of wavelengths, a plurality of wavelengths are required to comply with regulations such as zapping performance (JOIN latency) within 1.5 seconds as an average for packet processing.

  As an example of the function sharing, the identification and distribution of the multicast (MC) stream can be processed by software as long as the CPU has a high-speed processing capability, but hardware + config is desirable. In addition, the application system and ONU setting for uplink are assumed to be applications because the frequency and delay restrictions are loose.

  FIG. 14 is a diagram of the power saving control function. The processing to be configured includes a sleep proxy / traffic monitor, ONU wavelength setting, and transition between wavelength settings. These processes may include basic processes such as L3 packet processing (desirably including IPv6Parse), 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 a combination of basic processes. Further, the order may be changed.

  This main function is required to comply with regulations such as a transmission / reception rise time (receiver / transmitter) of 10 ms / 5 ms and a rise time (LC / OSU / OLT) of 100 ms / 1 s / 10 s. As an example of function sharing, a PS (Power Save) application, or depending on a signal, proxy processing can be used as an application. The power saving control state transition management (driver unit) requires speed, but can be an application. The traffic monitor can be a config only application.

  FIG. 15 is a diagram of the frequency / time synchronization function. The OLT subordinately synchronizes its own real-time clock (RTC) with the host device by SyncE (Synchronous Ethernet) (for frequency synchronization) and IEEE 1588v2 (time synchronization). Further, the correspondence between the PON super frame counter (SFC) and the absolute time (ToD: Time of Day) information is notified to the ONU using OMCI. These processes may be configured by holding a real-time clock, which is a basic process. Equivalent processing may be realized by a combination of basic processing. Further, the order may be changed.

  In this main function, frequency synchronization accuracy +/− 50 ppb (LTE FDD, TDD), time synchronization accuracy +/− 1 to 1.5 us (LTE TDD, small cell), +/− 1 us (G.987) .3) etc. are required. As an example of function sharing, the real-time clock itself is a device-dependent unit, and the time adjustment calculation to the host device can be an application (it can also be a device-dependent unit depending on accuracy).

  FIG. 16 is a diagram of the protection function. As processing to be configured, redundant switching (CT, SW, NNI, CONT, PON (Type A, B, C)) is provided. These processes may be composed of basic processes such as redundant path setting, switching trigger detection, switching notification transmission / reception, switching processing, and the like. Equivalent processing may be realized by a combination of basic processing. Further, the order may be changed.

  In this main function, forced switching is required to comply with regulations such as 50 ms or less. As an example of function sharing, an application can be used except for hardware switching trigger detection and switching processing such as failure detection. If an instruction to (from) the EMS is detected when a switching trigger is detected without setting a redundant path in advance, it depends on the device.

  The main 8 functions may be provided as necessary. For example, only the PON main signal processing function, the PON access control function, the L2 main signal processing function, the maintenance operation function may be provided, or other functions may be provided. May be. Further, the evaluation of whether each function can be softwareized is an example on the assumption that the processing capability of the OLT assumed in 2018 and the application of the soft switch are not assumed. It may be changed as appropriate assuming an assumed processing capacity and application of a soft switch. Even a function that can be softened may not be softened. The internal configuration of each function may be another configuration as long as the same function can be realized.

  Algorithms included in the main 8 functions are defined as main software areas. The function as the software area is set as a device-independent application on the device-independent APIs 21 and 22. For example, algorithms in the ONU registration / authentication function, DWBA function, setting / management / monitoring control function, and power saving control function that contribute to the differentiation service are treated as extended functions in the device-independent application. The MLD proxy application includes a multicast function.

  The extended function is an extended function depending on the importance of the update frequency of the function and the realization of the original specification. It is preferable to use middleware other than basic functions and device-independent applications, device-dependent software, and hardware that have a low update frequency or a low requirement for realization of original specifications. In particular, it is preferable to leave the functions that are limited by the processing capability of the software as hardware. For example, functions that contribute to service differentiation or high frequency of renewal such as DBA to improve main signal priority processing and line utilization efficiency, and management that is closely related to the operational flow of the operator and requires unique specifications for each operator From control functions to extended functions.

  An example of the architecture is shown in FIG. In the optical access system according to FIG. Complies with 989 series. The connection relationship shown below is an example, and the connection interposed therebetween may be a connection that does not intervene, or may be connected to only a part of a plurality of connection relationships, or may be other connections. . The same applies to other explanations. In an 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 to the L2 function is connected to NE control, and the setting / management application is connected to NE management. The low speed monitoring application (OMCI), the MLD proxy application, and the power saving application are each connected to the L2 function.

  The protection application is connected to the PLOAM Engine and the Embedded OAM Engine. The power saving application is connected to the PLOAM Engine via the OMCI and the high-speed monitoring application. The ONU registration authentication and the 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.

  FIG. 19 shows an example of capability deployment on the device. In the optical access system according to FIG. 19, an example is shown in which functions are distributed and arranged on a plurality of CPUs on a CPU version. In this example, the CPU of the CPU version is divided into three groups: CONT (controller version, controller, controller, etc. orientation, OSU orientation, SW orientation. Each of the three groups of CPUs may be a single CPU. It may be composed of a plurality of CPUs, or it may be a GPU (Graphics Processing Unit), an FPGA (Field Programmable Gate Array), a DSP (Digital Signal Processor), an ASIC (Application Specified Optimized Function), or the like. Or they may be included.

  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. Further, instead of the centralized arrangement in the CPU version, each group may be distributed and arranged in three PKGs (package, version) (Cont version, OSU, SW). The CONT connected to the device setting IF and the EMS-IF performs data input / output via each application group divided into three groups of CONT, OSU, and SW, as shown in FIG. These applications were a low-speed monitoring application (OMCI), a low-speed monitoring application (EMS-IF), and a setting management application. In addition, each application for SW is an MLD proxy application. Each application for OSU is 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 groups of functions are examples, and may be rearranged, or deleted / added abstracted.

  Middleware is installed in each OSU and switch. The middleware may be centrally installed in any one of them as long as the functions and the connectivity between the hardware can be secured. Each OSU includes an optical transceiver (λCard in the figure) having a predetermined wavelength. A control version (CONT. In the figure), which is a control unit in the OLT, controls each application for CONT. The CONT-oriented, OSU-oriented, and SW-oriented applications are connected to input / output data to / from each other via middleware or without middleware.

  Each application is an example of processing by a CPU on a CPU package. In the figure, each application is processed for the control version (CONT. In the figure) that is a control unit in the OLT, the process for the OSU package (OSU in the figure) provided with an optical transceiver (λCard in the figure), the OSU and the upper network. It is classified into three groups of processing for SW packages that exchange data with the device on the side.

  Power saving app, protection app, high speed monitoring app, DBA app, DWA app, ONU registration authentication app as OSU group, MLD proxy app as SW group, low speed monitoring app (OMCI), low speed monitoring app (EMS- as CONT group) IF), a setting management application. Furthermore, although centralized control is assumed in the CPU version, the classified applications of each group may be distributed and arranged in each PKG (Cont, OSU, SW).

  Moreover, you may arrange | position on either of Cont, OSU, SW, or those some combination irrespective of said classification | category. Further, the apparatus setting IF in the figure may be a part of the EMS-IF, or may be equivalent to the API 25 in FIG. Further, 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, such as GPU, NPU, DSP, or FPGA. The same applies to the other embodiments of the present application.

  FIG. 20 shows an example in which an application is arranged on a server or the like instead of the CPU package. The application processes on the server or the like, and the processing result is transmitted on the transmission line in a format that can be transmitted on the transmission line such as an Ethernet frame, and then arrives at the OLT. Here, the format that can be transmitted on the transmission path may be a frame other than the Ethernet frame, transmission of TDM, or the like, and via a converter (CONV. In the figure), but the OSU, SW, or λ card converts it. If it is possible to receive the processing result of the application without going through the machine, the converter is unnecessary. The server or the like may be equivalent to the external server 16 in FIG. 5 or may be equivalent to the proxy unit 15.

  FIG. 21 shows an example of processing other than an application and an application. In the figure, an example in which the enclosure of the CPU is processing by the basic function and the unique function, and the processing by the OSUMAC in the vendor-dependent portion is shown, but it is not limited to this classification. The CPU in this figure may be a part having the processing capability on the CPU package in FIG. OSUMAC assumes a dedicated LSI that performs OSU processing, but a general-purpose LSI may be used if equivalent processing is possible.

  In the optical access system according to FIG. 21, the CPU includes, as a first group, maintenance management function Ffault Management, maintenance operation function GTC / PMD Configuration, PON access processing function ONU Activation / Deactivation, and PON access processing function DBA.

The OSU MAC has a PON main signal processing function Framing, a security function such as encryption / decryption of the PON main signal processing function, a PON main signal processing function FEC function, and a frequency / time synchronization function. The OSU MAC may perform data processing in the order of XGEM Framer, encryption, XGTC Framer, FEC, PHY Framer, SP conversion, and 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 positioned at the preceding stage of the PHY Framer may be performed by the frequency / time synchronization function.

  FIG. 22 shows the processing of the application with the main 8 functions and G. This corresponds to the 989.3 functional diagram. As shown in FIG. 22, 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 FrameG Burd as PEMAM Part and FS Frame / Burst.

User Data Adapter includes Security Key Management (mgmt.), ONU Power Management (mgmt.), TWDM Channel Management (mgmt.), TWDM TC cc Function, and TWDM TC Function. Of AMCC PMC and Conventional TWDM PMD possessed by Layer, it is connected to AMCC PMC.

  FIG. 23 shows an example in which, in addition to user data, PLOAM and OMCI also receive corresponding ones from 14 or 15 or 16 in FIG. 5 via SW. 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 the example of FIGS. 1 and 2, the software area is a basic function, a management / control agent, extended functions A, B, C, and middleware. However, the software area is a service adaptation (encryption, fragment processing). , GEM (GPON Encapsulation Method) frame) / XGEM (XGPON Encapsulation Method) frame) X, PHY adaptation FEC, scramble, synchronous block generation / extraction, GTC (GPON Transmission Conversion frame, conversion frame SP) The encoding method may also be targeted.

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

  Assume an OLT including a plurality of OSUs, switches, an information processing unit, and a control unit. Each OSU includes a transmission / reception unit that is different for each wavelength. In this case, middleware is installed in each OSU and switch, and a software area such as a device-independent application is installed in the information processing unit.

  The information processing unit, that is, the CPU executes a device-independent application. The device-independent application includes an OSU extended function, a switch extended function, and a control unit extended function. The extended functions for OSU are, for example, a power saving application, a protection application, a DBA application, and an ONU registration authentication application. The extended 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. In this case, for example, it becomes as shown in FIGS.

  In the case of the DBA application, the middleware shown in FIGS. 1 and 2 or the basic function shown in FIGS. 3 and 4 operates the Embedded OAM Engine that is hardware of the TC layer. And the transmission / reception part which is the hardware of a PMD layer receives according to a DBA application. In addition, when a transmission / reception part also receives the upstream signal which does not follow DBA, you may not follow DBA application.

  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, OSU, switch, control unit, and information processing unit. For example, the information processing unit may be included in a transmission / reception unit, an OSU, a switch, or a control unit. Further, as shown in a diagram of a configuration example to be described later, a proxy unit or an external server that processes a signal input to and output from the switch may be provided on the NNI (Network-Network Interface) side of the switch. The external server may have 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 according to a request for processing capacity or processing delay. The OSU may include a switch (a switch unit 12 or a switch unit 13 described later), or may include a switch (a switch unit 12 in the case of including the switch unit 13 described later) separately from the switch. It is desirable that the switch functions are appropriately shared according to the processing capacity of the switch without overlapping between the switch unit 12 and the switch unit 13, but may be overlapped.

  The place where the softening function is provided is not limited to the information processing unit, and may be provided at a place where a plurality of arithmetic processes can be performed. For example, the location where the softwareization function is deployed is other than the transmission / reception unit, the OSU switch, the OSU switch, the OLT control unit, the OLT switch, the OLT information processing unit, the OLT switch, the control unit, and the information processing unit. Either a proxy unit that processes signals input to or output from the switch on the NNI side of the switch or a processing device such as an external server may be used.

  Further, the arrangement of the softening function may be arranged for each softening function, or may be a part of the softening function obtained by dividing a single softening function. For example, the part related to the transmission / reception unit other than the transmission / reception unit, for example, the switch of the OSU, the transmission / reception 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, the other of the OLT, It may be deployed somewhere or a combination of a plurality of deployment locations such as a proxy unit and an external server on the main signal path outside the OLT. Items related to PON termination other than PON termination processing deployment locations, for example, OSU transmission / reception unit, OSU switch, other than OSU transmission / reception unit and other than switch, OLT switch, OLT control unit, OLT information processing unit Other than that of the OLT, the proxy unit may be deployed outside the OLT, or on a combination of a plurality of deployment locations such as a proxy unit or an external server on the main signal path.

  Items related to ONU switches other than ONU switches, for example, transmission / reception unit, other than OSU transmission / reception unit and other switches, OLT switch, OLT control unit, OLT information processing unit, other than OLT, OLT It may be deployed somewhere on the main signal path outside the network such as a proxy unit, an external server, or a combination of a plurality of deployment locations. OLT switches related to OLT switches other than OLT switches, for example, transmission / reception unit, OSU switch, other than OSU transmission / reception unit and other switches, OLT control unit, OLT information processing unit, other than OLT, OLT It may be deployed somewhere on the main signal path outside the network such as a proxy unit, an external server, or a combination of a plurality of deployment locations.

  Further, the location where the softening function is deployed may be changed as appropriate according to the status of the deployment of the extended function, the computing capacity of the location where computation is possible, the computation load, power consumption, and the like.

  Here, with reference to FIG. 17, a description will be given of the main functions related to the main signal processing of the OLT and the relationship between the functions. The OLT function is transferred to the switch. A PON main signal processing function for performing PON section processing such as a PHY adaptation function, a framing function, and a service adaptation function is provided in the transmission / reception unit. PON access control functions such as an ONU registration / authentication function, a DBA control function, and a DWA function are provided in the information processing unit. L2 main signal processing functions such as VLAN control used in framing, priority control in the previous stage of the shaper, MuX / Dmux and Queue, and shaper in the previous stage of framing are provided in the switch. A multicast function such as a copy function at the former stage of the shaper and an MLD (Multicast Listener Discover) proxy used for copying is provided in the switch. As described above, the PON basic function is reduced by providing the PON main signal processing function and the PON access control function, which have been provided in the PON, to the switch. In particular, it is preferable that the L2 main signal processing is provided in the switch while avoiding duplication.

  In addition, although illustrated as a function of a switch in order of Classifier, Modifier, Policer / Shaper, Cross Connect, Queue, and Scheduler, it may be changed as appropriate. For example, in the upstream direction, if processing is not performed in the bandwidth allocation unit, the input from the ONU is removed from the preamble and burst overhead for burst transmission, the frame is decapsulated, the LLID is removed, and the PON All functions of Classifier, Modifier, Policer / Shaper, Cross Connect, Queue, and Scheduler may be implemented by the switch, or the Modifier, Cross Connect, Queue, and Schedule may be implemented by the switch.

  Furthermore, if a VID or the like that describes the path after the PON termination is assigned by the ONU, Cross Connect, Queue, or Schedule may be used. If the host network can be regarded as a single path, it may be Queue or Scheduler. Further, if DBA is performed so that the frames do not collide with each other in the cross connect, the classifier, modifier, policer / shaper, and cross connect can be obtained. Furthermore, if it is in the upstream direction and processing is not performed in the bandwidth allocation unit, the input from the ONU is removed from the preamble and burst overhead for burst transmission, the frame is decapsulated, the LLID is removed, and the PON If only the terminal is attached and a VID or the like describing the path after the PON terminal is assigned by the ONU, only the Cross Connect can be provided.

  Also, Classifier, Modifier, Policer / Shaper, Cross Connect, Queue, Scheduler, Classifier, Policer / Shaper, Modifier, Cross Connect, Queue, and Sch Modifier, Queue, Policer / Shaper, Cross Connect, and Scheduler, or Classifier, Queue, Policyr / Shaper, Modifier, Cross Connect, and Scheduler may be used. In consideration of unnecessary Policing / Shaping due to burst transmission caused by PON burst transmission and multiplexing of priority traffic such as multicast, and reception of leveled traffic on the receiving side, Queue is placed in front of Policer / Shaper. It is desirable to perform Policing / Shaping after leveling.

A unit (SW) 13 may be used.

  A transmission / reception unit (TRx) 11 having different wavelengths (λA to λN) is connected to the switch unit 12. TRx11 is autonomous, or controlled from other components such as SW12, SW13, control unit 14, proxy unit 15 and external server 16, or other components such as SW12, SW13, control unit 14, proxy unit 15 and external server 16 Controlled by the control transferred through the component, a part or all of the traffic of the ODN or SW 12 is sent to at least a part of the VLAN, priority, discard priority, destination, etc., or a combination thereof according to a predetermined procedure. Process with at least one of aggregating or distributing or allocating or duplicating or folding or transparent, or a combination thereof, with no additions, deletions, substitutions or changes.

  The switch unit (SW) 12 is connected to the switch unit (SW) 13. Here, in this communication system configuration, uplink communication is not necessarily aggregated. In the configuration of 1-1, the device at the subsequent stage as viewed from the ONU side (in this communication system configuration, exemplified by SW12, but may be SW13, proxy unit 15, etc.) is mainly distributed to each wavelength, but is distributed and aggregated.

  As described above, this embodiment defines past functions by defining at least some functional modules and input / output IFs, clarifying the functions to be ported between generations, and ensuring versatility and portability. By clarifying general-purpose functions among equipment vendors, it can be shared between vendors, thereby avoiding double development and reducing development and procurement costs. Furthermore, by clarifying the input / output IF for providing the extended function and ensuring the expandability, the unique function can be easily realized and the differentiated service can be provided in a timely manner.

  The configuration according to the present embodiment described above is the same in the following embodiments, and may be combined as appropriate. For example, in FIG. 1, this system illustrates the case where the configuration of the implementation unit is only TRx11 and switch units 12 and 13, but a location other than TRx11 and switch units 12 and 13, other locations, and PON termination. It is good also considering a location and the control part 14 as an implementation part.

(Embodiment 1-2)
In the embodiment 1-1, the configuration used for the TWDM-PON is illustrated, but may be applied to the TDM-PON. The TDM-PON is the same as the embodiment 1-1 except that it does not have to have a function of wavelength division multiplexing wavelength resources in the PON section of the ONU-OLT during the ONU, such as λ setting switching (DWA). It is.

(Embodiment 1-3)
In the embodiment 1-1, the configuration used for the TWDM-PON is exemplified, but the configuration may be applied to the WDM-PON. The WDM-PON is the same as the embodiment 1-1 except that it does not have to have the function of time-division multiplexing the bandwidth resources in the PON section of the ONU-OLT between the ONUs such as the DBA.

(Embodiment 1-4) Combination including OFDM-PON, CDM-PON, SCM-PON, and core multiplexing In Embodiment 1-1, the configuration used for TWDM-PON is illustrated, but resources other than wavelength and time are used. It may be applied to a shared PON. For example, the present invention may be applied to OFDM-PON that divides and multiplexes one-wavelength electric frequency resources, SCM-PON that divides and multiplexes one-wavelength electric frequency resources, and CDM-PON that divides and multiplexes codes. May be used in combination. It is the same if the function of wavelength division multiplexing the wavelength resource of the TWDM-PON is replaced with a function corresponding to a function required for division multiplexing to each resource to be multiplexed.

(Embodiment 2)
In the present embodiment, the configuration used for TWDM-PON performs GEM encapsulation. In this case, an adapter for generating a GEM frame is provided in the switch, and the GEM frame is conducted between the switch and the other parts.

  By transferring to the switch until GEM encapsulation, it is possible to exclude the L2 function from the protocol stack of other parts, and to avoid overlapping of the L2 function in the switch and other parts.

  Although TWDM-PON is used as an example, as in Embodiment 1-2 to Embodiment 1-4, if the frame for identification in the PON section is handled in the same manner, the same applies to other PONs. The effect is obtained. For example, in the case of IEEE standard GE-PON, 10GE-PON, etc., instead of a GEM frame, an LLID is assigned so that the frame with the LLID is connected between the switch and the other parts. Good.

(Embodiment 3)
In the present embodiment, control information used for TWDM-PON passes through a switch. In this case, instead of transferring the bridge function related to the switch, any one of PLOAM, Embedded OAM, and OMCI holding control information is framed as necessary and processed via the switch.

  By exchanging the control information via the switch, the processing other than the switch is lightened. In addition to the transfer of the present embodiment, transfer to the bridge function switch of the first and second embodiments may be performed.

  Although TWDM-PON is given as an example, if control information is handled in the same manner and processed via a switch, the same applies to other PONs as in Embodiment 1-2 to Embodiment 1-4. An effect is obtained.

  The present invention can be applied to the information communication industry.
