(Embodiment 1)
FIG. 1 is a diagram showing an example of the basic concept of the communication system 1. The communication system 1 includes a communication device 100 and a storage device 200. The communication device 100 is a device that executes communication with another communication device by an optical signal passing through an optical fiber network such as a PON (Passive Optical Network).

The communication device 100 is, for example, an OLT. The communication device 100 may be, for example, an OSU (Optical Subscriber Unit). The communication device 100 may be, for example, a combination of an OLT having or not having a switch unit (SW) for switching an optical signal and another switch unit (SW). The communication device 100 may be, for example, a combination of an OLT and an ONU. The communication device 100 may include a plurality of devices. In FIG. 1, the devices included in the communication device 100 are, for example, the OSU package unit 101 and the PON port unit 102. The OSU package unit 101 may include one or a plurality of PON port units 102, or may face each other.

Hereinafter, the storage device 200 is provided in a server (external server) installed in a server other than the communication device 100 (outside the communication device 100). The server is, for example, a control unit (CTL). The control device controls, for example, the equipment provided in the communication device 100.

The storage device 200 includes a holding unit 210. The holding unit 210 includes a memory 220. The memory 220 holds operational information. The operation information is information related to the operation of the equipment provided in the communication device 100. That is, the operation information is state information representing the state of the device provided in the communication device 100. For example, the operation information is a Mac table (Mac table) which is learning information such as setting value, ONU state information, EQD, authentication information, filter setting information, usage history (history information), billing information, contract information, and Mac address. MAC Table), insufficiency counter (Deficit Counter) related to bandwidth usage and bandwidth allocation, response such as Multicast Leave / Join, which may be the unfinished response itself, or even in a specific state thereof. good.

The communication system 1 may directly write the operation information used by the device such as the OSU package unit 101 or the PON port unit 102 into the holding unit 210. The communication system 1 may transfer the operational information held by the device such as the OSU package section 101 or the PON port section 102 from the device provided in the communication device 100 to the holding section 210 at all times or intermittently. ..

The upper limit of the intermittent cycle depends on the error of the state information. For example, assuming that 1 GB is an allowable error in the flow rate control, the error is equal to or less than the time interval in which the flow rate of 1 GB is generated. On the contrary, when the intermittent cycle is too long and the error exceeds the permissible value, the flow rate itself may be suppressed so that the error is less than or equal to the error.

The information (written information) written in the holding unit 210 may be the operation information itself or information based on the result of statistically processing the operation information. The written information may be information based on the sum of the information for a certain period, the exponential average, the moving average, the average in the form of resetting the history at a predetermined interval, and other statistical processing. The write information may be changed according to the bandwidth and bandwidth time product of the communication path required for writing and the processing cost required for writing.

As a method of writing to the holding unit 210, the original transfer path or means of the communication system 1 may be used. As a method of writing to the holding unit 210, a standardized means such as a mechanism for transferring an unknown packet to the controller such as OpenFlow may be used.

The operation information held by the holding unit 210 may be directly copied when the association with the user or the device is changed, only the pointer referring to the operation information held by the communication device 100 may be changed, or the user may change the operation information. And only the key associated with the communication device 100 or between the communication devices may be changed. By detecting the presence or absence of writing from the communication device 100 to the holding unit 210, it may be detected whether the communication device 100 is operating. By rewriting the operation information held by the holding unit 210 from, for example, a controller other than the communication device 100, the communication device 100 using the rewritten operation information may be instructed to change the operation.

When the operation information is written from the communication device 100-1 to the holding unit 210 by transcription, the instruction for transferring the operation information from the holding unit 210 to the communication device 100-2 is to transfer the operation information of the holding unit 210 to the communication device 100. -2 may be instructed at the timing of use.

For example, the communication device 100-1 limits the allocated bandwidth of the user's communication according to the value indicating the usage history (history information) of the user's communication. The user is, for example, a user of a communication terminal subscribed to a flat-rate communication charge plan, and uses the communication service of the communication device 100-2 after the communication device 100-1. The communication device 100-1 rewrites the value of the user's communication usage history stored in the holding unit 210. As a result, the communication device 100-2 that provides the communication service to the user by using the usage history of the user who used the communication device 100-1 communicates with the user (bandwidth excess user) who exceeds the limit of the communication amount. It is possible to limit the allocated bandwidth of.

For example, as a setting for limiting the allocated bandwidth according to the value of the usage history, the allocated bandwidth limitation may be effectively instructed by greatly rewriting the value of the usage history.

When there are a plurality of memories 220, the holding unit 210 may distribute the operation information of the device of the communication device 100 to one or more memories 220 selected as the holding destination among the plurality of memories 220. When there are a plurality of communication devices 100, the holding unit 210 may distribute the operation information for each communication device 100 to one or more memories 220 selected as the holding destination.

For example, a memory for each wavelength, OSU, OLT, etc., and a memory for each ONU, user, Alloc-ID, etc. are provided, and when the ONU, user, or Alloc-ID is replaced with respect to the wavelength, OSU, OLT, etc., the wavelength, OSU, or The memory may be rewritten to correspond to the OLT or the like, or the memory may be left as it is and only the pointer associated with the wavelength or the OSU or the OLT or the like may be changed. The latter is more preferable because the time for rewriting the memory can be omitted, but the latter is not limited to the latter.

FIG. 2 is a diagram showing an example of operation information arrangement in the first embodiment and an operation information arrangement in a comparative example. The first embodiment is particularly suitable for the protection across the OLT shown in FIG.
OSU (a set of OSU package unit 101-1 and PON port unit 102-1, and OSU package unit 101-2 and PON port unit 102) housed in different OLTs (communication device 100-1 and communication device 100-2). When the storage device 200 is attached to the management system, the operation system OSU communicates with the ONU based on the setting information given to the OSU from the management system and the operation information generated during the operation. do. FIG. 3 shows an example of ONU operation information for each main function of OLT. Here, the setting information is information given to the communication device (communication device 100-1 or a set of the OSU package unit 101-1 and the PON port unit 102-1) by the management system, and is held outside the communication device. Is easy information. Since the operation information is generated in the communication device during operation and used for operation in the communication device, the communication device in the comparative example does not hold it outside the device. Therefore, in the communication device in the comparative example shown on the left side of FIG. 2, in the device that does not hold the operation information outside the device, switching by protection (from the pair of the OSU package unit 101-1 and the PON port unit 102-1 to the OSU package). When switching to the set of the unit 101-2 and the PON port unit 102-2), the operation information is lost.

FIG. 4 shows the effects when the operational information shown in FIG. 3 is lost and the recovery method of the operational information. As shown in FIG. 4, it was difficult to provide services in compliance with communication interruptions and contracts until information was acquired by communication with an external server, for example, and the lost operational information was recovered. In the present embodiment, since the operation information is held in the storage device 200 attached to the management system outside the device, the loss of the operation information can be suppressed, and the communication interruption and the service provision interruption in compliance with the contract can be suppressed. In particular, it is desirable that the storage device 200 is a shared device having redundancy and collectively manages the operation information of a plurality of OLTs. Collective management with a shared device is also desirable from the viewpoint of separating the functions of OLT and making them into parts.

FIG. 5 shows the constraint conditions for arranging the operation information. As shown in FIG. 5, a shared device is desirable from the viewpoint of redundancy of operation information, necessity of copying operation information before switching / accommodation, and inheritance of operation information at the time of OLT failure. On the other hand, when the communication band is consumed by sending and receiving the operation information between the shared device and the OLT, and the shared device and the OLT are separated, there is a restriction that it takes time to transfer the operation information. In the present embodiment, the operation information is arranged outside the communication device by setting the communication band consumed by sending and receiving the operation information and the time required for transferring the operation information so as to satisfy the constraint shown in FIG. As the transmission time satisfying the constraint, for example, if the response is a specified PLOAM response of 0.75 ms between OLT and ONU, the process is required from the time allowed for the process such as 0.75 ms. The round-trip transmission time of the OSU-storage device, which is less than or equal to the time obtained by subtracting the time. If there is a time variation (jitter) in the start time or processing time of the transmission time or the time required for processing such as framing for transmission or reading / writing from the storage device, the time with the maximum jitter delay added. May be the time required for processing. The time allowed for processing and response may be longer than the specified value in standardization or the like, or longer than the specified value if the opposing device allows it. For example, in the case of PLOAM, the value may be higher than that if the ONU and OLT operate in correspondence with each other, such as not interrupting communication even for 0.75 milliseconds or longer.
In the present embodiment, in order to satisfy the constraint condition and hold the operating state outside the communication device 100, it is possible to shorten the time until the communication device transitions to a specific state.

In order to match the operational information held by the communication device 100 and the storage device 200, the following may be used.
A) Operation information is generated by either the communication device 100 or the storage device 200 or other devices, and the operation information generated by the communication device 100 or the storage device 200 or other devices is received and the communication device is received. The operation information is updated after the lapse of time required for the 100 and the storage device 200 to reflect the operation information.
B) Operation information is generated by either the communication device 100 or the storage device 200 or other devices, and the operation information generated by the communication device 100 or the storage device 200 or other devices is received and the communication device is received. The 100 and the storage device 200 update the operation information in synchronization with the time based on the time information.
C) Reception that the operation information is generated by any of the communication device 100, the storage device 200, or other device, and the operation information generated by the communication device 100, the storage device 200, or other device is received. Receive a response and update.
D) Operation information is generated by either the communication device 100, the storage device 200, or other device, and the communication device 100, the storage device 200, or other device receives the most generated operation information, and then switches. Update synchronously with instructions.

In the example of switching, one-to-one switching is illustrated, but it may be N: 1, N: M (N, M are integers of 1 or more), and in that case, the backup system is the operation system of N. The operation information of the operation system to be switched may be selected from the operation information.

FIG. 6 is a diagram showing an example of the configuration of the communication system 1. In FIG. 6, the storage device 200 having the holding unit 210 is provided in the server. The server controls the OLT and the switch unit (SW). The server may control the OLT and the switch unit based on a predetermined protocol, for example, a predetermined protocol such as OPENFLOW (registered trademark) technology, NETCONF / YANG, or SNMP (Simple Network Management Protocol).

FIG. 7 is a diagram showing an example of bandwidth allocation limitation. In FIG. 7, the server changes the bandwidth setting of the communication terminal subscribed to the communication flat-rate plan by comparing the operation information (at least one of the OSU allocation history or the SW flow rate) with the contract information. In FIG. 7, OSU1a is an operational OSU.

FIG. 8 is a diagram showing an example of a process of switching the OSU that emits an optical signal when the operation information of the server holding is not updated for a predetermined period in the case of the type B switching and the server holding of the operation information. In FIG. 8, it is detected whether or not the OSU is operating by detecting the presence or absence of writing to the holding unit 210. Switching instructions from other servers (in the case of forced switching, etc.), LOS (Loss of Signal), LOBi (Loss of burst for ONUi), DyingGasp, OSU power off, OSU removal, core wire removal, new to the holding unit 210 It may be detected by whether or not there is an input of.
In addition, the sum of the band requests from the ONU and the flow rate of the OSU, OLT, or SW are held by the holding unit, and the held values are different from each other by a predetermined value or more without appropriate processing such as flow rate limitation. When it occurs, it may be detected as an abnormality of the switching trigger.

For example, in the case of OSU switching from OSU1a to OSU2a (server retention, forced switching, cold standby (Cold Standby)), the frame is buffered by an external device such as a switch (SW), and within 50 milliseconds after the instruction is given. The backup system OSU (Cold Standby) starts to start, the downlink traffic has no frame loss, the uplink traffic has no frame loss up to the ONU uplink buffer amount, and the communication with the operation information of the operation system is switched without the range processing.

For example, in the case of OSU switching (information inheritance, failure, Cold Standby, buffering with SW in preparation for switching in advance), the package of the operational OSU (PKG, OSU package section 101 or PON port section 102 in FIG. 1). Alternatively, the fiber is removed and the backup OSU (Cold Standby) starts to start within the set switching protection time and the error +1 setting unit, so for downlink traffic, the set switching protection time +1 setting unit is the upper limit. Frame loss occurs. Further, in the uplink traffic, the OSU is switched without causing frame loss up to the ONU uplink buffer amount.

For example, in the case of OSU switching (forced switching, hot standby), the backup OSU (Cold Standby) starts to start within 50 milliseconds after the instruction, and no frame loss occurs in downlink traffic. In the uplink traffic, frame loss does not occur up to the amount of the ONU uplink buffer, and communication in the operation information of the operation system is switched without the range processing.

For example, in the case of ONU switching (forced switching, hot standby), startup of (Cold Standby) starts in the standby ONU within 50 milliseconds after the instruction, no frame loss occurs in downlink traffic, and in uplink traffic. A frame loss up to the time until activation, for example, 50 milliseconds, occurs, and communication of operation information of the operation system OSU is started.

FIG. 9 is a diagram showing an example of external implementation of the OLT function. In FIG. 9, by implementing the OLT function on hardware (IA server, switch (SW), etc.) outside the OLT, it is easy to add or change the function according to the communication service by utilizing the existing OLT hardware. To.

The upper right figure of FIG. 9 is a diagram showing an example of the architecture. In this example, the communication device consists of existing / commercial hardware and external hardware. For example, the existing / commercial hardware is a non-general-purpose device-dependent unit 110 that depends on the device, a middleware unit 120 that hides the difference between hardware and software on the external hardware, and a general-purpose unit whose operation does not depend on the device. The device-independent application unit 130 is provided. Therefore, the device-dependent section (vendor-dependent section) below the middleware in the figure is a functional section that depends on the standard to which the device of the communication device conforms and the manufacturing vendor of the device. Further, the device-independent application unit 130 is a functional unit that does not depend on the standard to which the device of the communication device conforms or the manufacturing vendor of the device.
The middleware unit and the device-independent application unit are connected via a device-independent API (Application Programming Interface), which is a device-independent input / output interface (IF: Interface). For example, the software section, OAM (Operation Administration and Maintenance), hardware section and hardware section of the device-dependent section, and the middleware section 120 on the external hardware are device-dependent APIs that are device-dependent input / output interfaces. And connected via device-to-device connection between existing / commercial hardware and external hardware. As a result, the communication device 100 facilitates the flexible and quick addition of the extended function unit (unique function unit) by the device-independent application unit 130, and can provide the communication service in a timely manner. Here, the device-dependent unit may be the maintenance operation, access control, physical layer processing, and optical module shown in FIG. 9, and depends on the configuration of the device itself.
For example, priority processing of the main signal, DBA (Dynamic Bandwidth Assignment) for improving line utilization efficiency, and other frequently updated functions or functions that contribute to communication service differentiation are prioritized, and the device-dependent unit 110 or device-independent. You may decide to use the application unit 130. Further, the device-independent application unit 130 may be used because the difference is small with respect to at least one of the standard, generation, method, system, device type, and manufacturing vendor to which the device to be shared conforms.

Any of the conforming standards, generations, methods, systems, equipment types, manufacturing vendor features, even if it is not optimal for at least one of the conforming standards, generations, methods, systems, equipment types, or manufacturing vendors. In order to generalize the above, a common IF (common interface) for executing a function may be used. The common IF may include IFs and parameters that are not used in any of the standards, generations, methods, systems, device types, and manufacturing vendors to which the device-dependent unit 110 conforms.

Convert the interface (IF), parameters, etc. to at least one of the middleware unit 120, the driver of the device-dependent unit 110, and the device-dependent application unit 150 (vendor-dependent application unit) so as to correspond to the device-dependent unit 110. A conversion function unit and a function unit that automatically sets corresponding to insufficient IFs and parameters may be further provided.

The device-dependent unit 110 includes a hardware unit and a software unit. The software section executes device-dependent drivers, firmware, applications, and the like.

The device-dependent unit 110 is a PMD (Physical Medium Dependent) connected to a physical medium, a MAC, a PMA (Physical Medium Attachment) for serializing data, a PCS (Physical Coding Sublayer) for encoding data, or a PHY. It is not necessary to have a part. For example, it may have only optical-related functions without providing low-level signal processing such as modulation / demodulation signal processing, forward error correction, code decoding processing, and encryption processing.

The device-independent application unit 130 is, for example, a management / control agent unit 133 that acquires data from an EMS (Element Management System), an extended function unit 131-1 to 131-3, and a basic function unit 132. Hereinafter, matters common to the extended function units 131-1 to 131-3 will be referred to as "extended function unit 131" by omitting a part of the reference numerals. EMS is, for example, a network element (NE) controller. The device-independent application unit 130 may not include any of the management / control agent unit 133, the extended function unit 131, and the basic function unit 132.

The device-independent application unit 130 may further include configurations other than the management / control agent unit 133, the extended function unit 131, and the basic function unit 132. For example, when the extended function unit 131 is unnecessary, the device-independent application unit 130 does not have to include the extended function unit 131. Further, the device-independent application unit 130 may include one or more extended function units 131.

It is preferable that the extended function unit 131 can be added, deleted, replaced or changed independently without affecting other functions unnecessarily. For example, the extension function unit 131 may be added, deleted, replaced, or changed as appropriate when, for example, a multicast service or an extension function unit 131 that executes power saving measures is required according to a service request. ..

The basic function unit 132 may be included in the device-independent application unit 130 as a part of the extended function unit 131, or may be replaced by a function unit lower than the middleware unit 120. When the extended function unit 131 includes the basic function unit 132, the device-independent application unit 130 does not have to include the basic function unit 132. When a functional unit lower than the middleware unit 120 replaces the basic function unit 132, the device-independent application unit 130 does not have to include the basic function unit 132. When the extended function unit 131 includes the basic function unit 132 and the function unit lower than the middleware unit 120 substitutes for the basic function unit 132, the device-independent application unit 130 does not have to include the basic function unit 132.

When the management / control agent unit 133 automatically sets according to a predetermined setting without receiving communication from the EMS 140, the management / control agent unit 133 does not have to input / output with the EMS 140. Further, when the management / control agent unit 133 does not have the management setting function and the other device-independent application unit 130, the basic function unit 132, or the device-dependent unit 110 has the management setting function, the device-independent application unit 130 The management / control agent unit 133 may not be provided.

Information may be directly input / output between the EMS 140 and the device-independent application unit 130. Further, the device-dependent unit 110 does not have to include the NE management / control unit 115 and the IF of the NE management / control unit 115.

The basic function unit 132 may be included in the device-independent application unit 130 as a part of the extended function unit 131, or may be replaced by a lower function unit of the middleware unit 120. When the extended function unit 131 includes the basic function unit 132, or when the lower function unit of the middleware unit 120 replaces the basic function unit 132 or is a combination thereof, the device-independent application unit 130 is the basic function unit. 132 may not be included. Further, a part of the basic function unit 132 may be replaced by the device-dependent application unit 150 of the lower function unit of the middleware unit 120.

When the management / control agent unit 133 automatically sets according to a predetermined setting, it is not necessary to input / output information to / from the EMS 140. Further, when the management / control agent unit 133 does not have the management setting function and the other device-independent application unit 130, the basic function unit 132, or the device-dependent unit 110 has the management setting function, the device-independent application unit 130 manages. -The control agent unit 133 does not have to be provided. Information may be directly input / output between the EMS 140 and the device-independent application unit 130.

For input / output between the device-independent application unit 130 and the device-dependent unit 110, for example, the DBA application unit and the protection application unit input / output information to and from the embedded OAM engine of the TC layer. The DWBA (Dynamic Wavelength and Bandwidth Assignment) application and the ONU registration authentication application unit input / output information to and from the PLOAM engine (Engine) of the TC layer.

The power saving application unit inputs / outputs information to and from the OMCI (ONU Management and Control Interface) and the L2 main signal processing function unit (L2 function unit). The MLD (Multicast Listener Discover) proxy application unit inputs and outputs information to and from the L2 function unit. The low-speed monitoring application (OMCI) inputs and outputs information to and from OMCI. The OMCI and L2 functional units operate the XGEM (XGPON Encapsulation Method) framer (XGEM Framer) and encryption. Here, the DWBA and the DBA may be separate, integrated, or combined. For example, the management / control agent unit 133 is an application unit of the maintenance operation function, and inputs / outputs information to and from EMS140, which is an NE controller or the like for the NE management / control unit 115.

The implementation of the device-independent application unit 130 may have a priority. For example, the management / control agent unit 133 has the highest priority. Below the second priority is, for example, a DBA application, a DWBA application, a power saving application, an ONU registration authentication application, an MLD proxy application, a protection application, and a low speed monitoring application (OMCI).

The device-independent application unit 130 describes the device vendor, method, device type, device generation, for example, ITU-T G.M. TWDM-PON (Time and Wavelength Division Multiplexing --Passive Optical Network) conforming to the 989 series and ITU-T G. XG-PON conforming to the 987 series and ITU-T G. G-PON conforming to the 984 series and ITU-T G. It is an application that operates regardless of any of the 983 series compliant BPON. The device-independent application unit 130 differs in device vendor, method, device type, device generation, for example, 10GE-PON conforming to IEEE802.3av and IEEE1904.1, and GE-PON conforming to IEEE802.3ah. It is an application that works regardless of.

The management / control agent unit 133 inputs / outputs to and from the EMS 140 and the middleware unit 120. The middleware unit 120 inputs / outputs NE management information and control information to / from the NE management / control unit 115. The NE management / control unit 115 may directly send / receive NE management information and control information to and from the EMS 140 without going through the middleware unit 120, or may send / receive NE management information and control information via the management / control agent unit 133. You may send and receive.

The middleware unit 120 inputs / outputs information via the device-independent application unit 130 and the device-independent API 21. The middleware unit 120 inputs / outputs information to / from the OAM unit 114, the driver, firmware, and the hardware unit 111 or 112 of the device-dependent unit 110 via the device-dependent API 23. The middleware unit 120 outputs the input information as it is or in a predetermined format. For example, if the output destination is each part of the device-independent application unit 130, the middleware unit 120 converts the information into the input format of each part of the device-independent API 21. If the output destination is the OAM section 114 of the device-dependent section 110, the driver, the firmware, the hardware section 111 or 112, the middleware section 120 converts the format of the device-dependent API 23 into the format to be input to each, and then terminates. After performing the predetermined processing, the information is transmitted to the output destination.

At the time of input, the middleware unit 120 deletes unnecessary input information at each input destination, and if there is insufficient information, it can collect and supplement it via another device-independent API 21 or device-dependent API 23. desirable. Further, at the time of input to the middleware unit 120, it may be broadcast or multicast to broadcast to a related application or the like.

The middleware unit 120 and the device-dependent unit 110 are illustrated as a single unit, but each may be composed of a plurality of units. When the hardware of the device-dependent unit 110 includes a plurality of processors, the middleware unit 120 may input / output across the processors and hardware by using interprocessor communication or the like. The device-independent application section 130 and the device-independent application section 130 may be arranged in the user space on a single processor as an execution program such as a DLL (Dynamic Link Library), or on a plurality of processors. It may be arranged in the user space.

Further, the device-independent application unit 130 may be arranged in the kernel space after securing input / output IFs such as API, or may be arranged together with the middleware unit 120 having an interface that can be independently replaced with firmware or the like. Alternatively, it may be incorporated into firmware or the like and recompiled. The user space and kernel space may be any combination for each device-independent application unit 130.

The device-independent application unit 130 corresponding to the same function may be implemented in both the user space and the kernel space. In this case, for example, it may be switched and either one may be selected, both may be processed in cooperation, or the actual processing may be performed by only one of them. The same applies to the software of the device-dependent unit 110.

Desirably, the more high-speed processing such as main signal processing, DBA processing, and low-layer signal processing is required, the more there is a trade-off with the immediacy of expandability / replacement, but high-speed processing with less overhead is expected. It is desirable to incorporate it in kernel space or firmware. The processor in which the device-dependent application unit 150 is arranged is also the user space of the processor that performs actual processing or a processor in the vicinity thereof from the viewpoint of the influence on other programs due to the limitation of the bus and speed due to the inter-processor communication, the occupation of the communication path, and the like. It is desirable to place it in the kernel space or on the firmware. However, in order to reduce the capacity of the processor that performs the actual processing or a processor in the vicinity thereof, the communication cost due to the inter-processor communication increases, but the processing may be performed by a remote processor.

It is desirable that the device-independent API 21 is provided in the middleware unit 120 in advance assuming the extended function unit 131 to be added, but it is necessary in a form of suppressing modification of the device-dependent API 23 and other device-independent application units 130. It may be added or deleted accordingly.

The related messages are, for example, ONU-OLT notifications related to wavelength switching, such as PLOAM and OMCI. This is the result of monitoring the message and the link status between the ONU and the OLT. The external hardware (server) is from the upper device when the customer device ahead of the OLT, ONU, or ONU cannot respond during wavelength switching. The proxy response may be sent from / to the customer device ahead of the OLT, ONU, or ONU, if necessary. For the message related to wavelength switching from the higher-level device.

Next, as an example, the operation and the like will be illustrated on the premise of an OLT (Optical Line Terminal) of a PON compliant with the ITU-T recommendation such as a TWDM-PON (Time and Wavelength Division Multiplexing-Passive Optical Network) system. Here, TWDM-PON is used, but the PON may be a PON other than the TWDM-PON conforming to the ITU-T recommendation. For example, the PON may be an IEEE standard compliant PON such as GE-PON and 10GE-PON. The TC (Transmission Convergence) layer and PMD (Physical Medium Dependent) layer are the same if they are read as the corresponding layers in the standard.

(Embodiment 1-1)
In the first embodiment, the configuration of the communication system 1 used for the TWDM-PON will be described. Hereinafter, examples 1 to 5 of the architecture of the communication device 100 will be described as an example of the architecture of the communication device 100 of the communication system 1. The architecture of the communication device 100 of the communication system 1 may be an architecture other than the first to fifth examples of the architecture of the communication device 100. For example, the software part of the communication device 100 in the first to fifth examples of the architecture may be a hardware part.

(First example of architecture)
FIG. 14 is a diagram showing a first example of the architecture of the communication device 100. In the first example of the architecture, the communication device 100 has a non-general-purpose device-dependent unit 110 whose operation depends on the device, a middleware unit 120 which hides the difference in hardware and software of the device-dependent unit 110, and an operation on the device. It includes a general-purpose device-independent application unit 130 that does not depend on the device. Therefore, the device-dependent section 110 (vendor-dependent section) is a functional section that depends on the standard to which the device of the communication device 100 conforms and the manufacturing vendor of the device. Further, the device-independent application unit 130 is a functional unit that does not depend on the standard to which the device of the communication device 100 conforms or the manufacturing vendor of the device.

The middleware unit 120 and the device-independent application unit 130 are connected via a device-independent API 21 (Application Programming Interface), which is a device-independent input / output interface (IF). The device-dependent section 110 is composed of, for example, a software section 113, an OAM (Operation Administration and Maintenance), a hardware section 111, and a hardware section 112, and the middleware section 120 is a device that is a device-dependent input / output interface. It is connected via the dependent API 23. The NE management / control unit 115 and the middleware unit 120 are connected via a device-dependent API 25, which is a device-dependent input / output interface.

Hereinafter, the functional part that executes the process is referred to as an "execution part". Which function execution unit is the device-dependent unit 110 or the device-independent application unit 130 depends on the limitation derived from the processing for realizing the middleware unit 120 and the device-independent application unit 130, for example, the processing capacity of the software. In addition to the restrictions derived from it, it may be determined according to the frequency of function updates, the importance of extended functions, and the like. As a result, the communication device 100 facilitates the flexible and quick addition of the extended function unit (unique function unit) by the device-independent application unit 130, and can provide the communication service in a timely manner.

For example, priority processing of the main signal, DBA (Dynamic Bandwidth Assignment) for improving line utilization efficiency, and other frequently updated functions or functions that contribute to communication service differentiation are prioritized, and the device-dependent unit 110 or device-independent. You may decide to use the application unit 130. Further, the device-independent application unit 130 may be used because the difference is small with respect to at least one of the standard, generation, method, system, device type, and manufacturing vendor to which the device to be shared conforms.

Any of the conforming standards, generations, methods, systems, equipment types, manufacturing vendor features, even if it is not optimal for at least one of the conforming standards, generations, methods, systems, equipment types, or manufacturing vendors. In order to generalize the above, a common IF (common interface) for executing a function may be used. The common IF may include IFs and parameters that are not used in any of the standards, generations, methods, systems, device types, and manufacturing vendors to which the device-dependent unit 110 conforms.

At least one of the middleware unit 120 shown in FIGS. 14 and 15, the driver of the device-dependent unit 110 shown in FIGS. 16 and 17, and the device-dependent application unit 150 (vendor-dependent application unit) shown in FIGS. 15 and 17. In addition, a conversion function unit that converts an interface (IF), parameters, etc. so as to correspond to the device-dependent unit 110, and a function unit that automatically sets corresponding to the insufficient IF, parameters, etc. may be further provided.

In FIG. 14, the device-dependent unit 110 includes hardware units 111 and 112 and software units 113. The hardware unit 111 (PHY) executes from the physical layer to the processing related to optical transmission / reception (PHYsical sublayer processing). The hardware unit 112 (MAC) executes MAC (Media Access Control) processing. Hardware units 111 and 112 depend on conforming standards and manufacturing vendors. The software unit 113 is an execution unit for executing a device-dependent driver, firmware, application, and the like.

In addition to these, the hardware units 111 and 112 of the device-dependent unit 110 may include a general-purpose server, a layer 2 switch, and the like. The device-dependent unit 110 does not have to include the hardware unit 112 (MAC). The device-dependent unit 110 does not have to include a part of the hardware unit 111 (PHY). For example, the device-dependent unit 110 may have only optical-related functions without providing low-level signal processing such as modulation / demodulation signal processing, forward error correction, code decoding processing, and encryption processing. The device-dependent unit 110 does not have to include a PCS (Physical Coding Sublayer) that encodes data. The device-dependent unit 110 does not have to include a PMA (Physical Medium Attachment) for serializing data and a PCS. The device dependent unit 110 does not have to include a PMD (Physical Medium Dependent) connected to a physical medium. When the middleware unit 120 directly drives, controls, operates or manages the hardware units 111 and 112 of the device-dependent unit 110 without going through the software unit 113, the device-dependent unit 110 may not include the software unit 113. ..

The device-independent application unit 130 is, for example, a management / control agent unit 133 that acquires data from an EMS (Element Management System), an extended function unit 131-1 to 131-3, and a basic function unit 132. Hereinafter, matters common to the extended function units 131-1 to 131-3 will be referred to as "extended function unit 131" by omitting a part of the reference numerals. EMS is, for example, a network element (NE) controller. The device-independent application unit 130 does not have to include any one of the management / control agent unit 133, the extended function unit 131, and the basic function unit 132, and the management / control agent unit 133 is the basic function unit 132. The management / control agent unit 133 may be included in the basic function unit 132 or the middleware unit 120.

The device-independent application unit 130 may further include configurations other than the management / control agent unit 133, the extended function unit 131, and the basic function unit 132. For example, when the extended function unit 131 is unnecessary, the device-independent application unit 130 does not have to include the extended function unit 131. Further, the device-independent application unit 130 includes one or more extended function units 131.

It is preferable that the extended function unit 131 can be added, deleted, replaced or changed independently without affecting other functions unnecessarily. For example, the extension function unit 131 may be added, deleted, replaced, or changed as appropriate when, for example, a multicast service or an extension function unit 131 that executes power saving measures is required according to a service request. ..

The basic function unit 132 may be included in the device-independent application unit 130 as a part of the extended function unit 131, or may be replaced by a function unit lower than the middleware unit 120. When the extended function unit 131 includes the basic function unit 132, the device-independent application unit 130 does not have to include the basic function unit 132. When a functional unit lower than the middleware unit 120 replaces the basic function unit 132, the device-independent application unit 130 does not have to include the basic function unit 132. When the extended function unit 131 includes the basic function unit 132 and the function unit lower than the middleware unit 120 substitutes for the basic function unit 132, the device-independent application unit 130 does not have to include the basic function unit 132.

When the management / control agent unit 133 automatically sets according to a predetermined setting without receiving communication from the EMS 140, the management / control agent unit 133 does not have to input / output with the EMS 140. Further, when the management / control agent unit 133 does not have the management setting function and the other device-independent application unit 130, the basic function unit 132, or the device-dependent unit 110 has the management setting function, the device-independent application unit 130 The management / control agent unit 133 may not be provided.

Information may be directly input / output between the EMS 140 and the device-independent application unit 130. Further, the device-dependent unit 110 does not have to include the NE management / control unit 115 and the IF of the NE management / control unit 115.

The basic function unit 132 may be included in the device-independent application unit 130 as a part of the extended function unit 131, or may be replaced by a lower function unit of the middleware unit 120. When the extended function unit 131 includes the basic function unit 132, or when the lower function unit of the middleware unit 120 replaces the basic function unit 132 or is a combination thereof, the device-independent application unit 130 is the basic function unit. 132 may not be included. Further, a part of the basic function unit 132 may be replaced by the device-dependent application unit 150 of the lower function unit of the middleware unit 120.

When the management / control agent unit 133 automatically sets according to a predetermined setting, it is not necessary to input / output information to / from the EMS 140. Further, when the management / control agent unit 133 does not have the management setting function and the other device-independent application unit 130, the basic function unit 132, or the device-dependent unit 110 has the management setting function, the device-independent application unit 130 manages. -The control agent unit 133 does not have to be provided. Information may be directly input / output between the EMS 140 and the device-independent application unit 130.

For input / output between the device-independent application unit 130 and the device-dependent application unit 110, for example, the DBA application unit and the protection application unit input / output information to and from the embedded OAM engine of the TC layer. The DWBA (Dynamic Wavelength and Bandwidth Assignment) application and the ONU registration authentication application unit input / output information to and from the PLOAM engine (Engine) of the TC layer.

The power saving application unit inputs / outputs information to and from the OMCI (ONU Management and Control Interface) and the L2 main signal processing function unit (L2 function unit). The MLD (Multicast Listener Discover) proxy application unit inputs and outputs information to and from the L2 function unit. The low-speed monitoring application (OMCI) inputs and outputs information to and from OMCI. The OMCI and L2 functional units operate the XGEM (XGPON Encapsulation Method) framer (XGEM Framer) and encryption. Here, the DWBA and the DBA may be separate, integrated, or combined. For example, the management / control agent unit 133 is an application unit of the maintenance operation function, and inputs / outputs information to and from EMS140, which is an NE controller or the like for the NE management / control unit 115.

The implementation of the device-independent application unit 130 may have a priority. For example, the management / control agent unit 133 has the highest priority. Below the second priority is, for example, a DBA application, a DWBA application, a power saving application, an ONU registration authentication application, an MLD proxy application, a protection application, and a low speed monitoring application (OMCI).

G-PON conforming to the 984 series and ITU-T G. It is an application that operates regardless of any of the 983 series compliant BPON. The device-independent application unit 130 differs in device vendor, method, device type, device generation, for example, 10GE-PON conforming to IEEE802.3av and IEEE1904.1, and GE-PON conforming to IEEE802.3ah.

The middleware unit 120 outputs the input information as it is or in a predetermined format. For example, if the output destination is each part of the device-independent application unit 130, the middleware unit 120 converts the information into the input format of each part of the device-independent API 21. If the output destination is the OAM section 114 of the device-dependent section 110, the driver, the firmware, the hardware section 111 or 112, the middleware section 120 converts the format of the device-dependent API 23 into the format to be input to each, and then terminates. After performing the predetermined processing, the information is transmitted to the output destination.

Further, at the time of input to the middleware unit 120, it may be broadcast or multicast to broadcast to a related application or the like.

In FIG. 14, the middleware unit 120 and the device-dependent unit 110 are illustrated as a single unit, but each may be composed of a plurality of units. When the hardware of the device-dependent unit 110 includes a plurality of processors, the middleware unit 120 may input / output across the processors and hardware by using interprocessor communication or the like. The device-independent application section 130 and the device-independent application section 130 may be arranged in the user space on a single processor as an execution program such as a DLL (Dynamic Link Library), or on a plurality of processors. It may be arranged in the user space.

Further, the device-independent application unit 130 may be arranged in the kernel space after securing input / output IFs such as API, or may be arranged together with the middleware unit 120 having an interface that can be independently replaced with firmware or the like. Alternatively, it may be incorporated into firmware or the like and recompiled. The user space and kernel space may be any combination for each device-independent application unit 130.

It is desirable to incorporate it in kernel space or firmware. The processor in which the device-dependent application unit 150 is arranged is also the user space of the processor that performs actual processing or a processor in the vicinity thereof from the viewpoint of the influence on other programs due to the limitation of the bus and speed due to the inter-processor communication, the occupation of the communication path, and the like.

(Third example of architecture)
FIG. 16 is a diagram showing a third example of the architecture of the communication device 100. In FIG. 16, instead of the middleware unit 120 described in the first example of the architecture, the basic function unit 132 performs input / output with the hardware units 111 and 112 and the extended function unit 131. The other device-independent application unit 130 is the same as the first example of the architecture.

Compared with the first example of the architecture, it is not necessary to create a standard, a generation, a method, a system, a device type, and a manufacturing vendor that conform to the middleware unit 120 having the device-dependent API 24 for each device. As a result, the communication device 100 has the effect that more functions can be generalized and ported between generations between devices, the connectivity can be easily verified, and the functions of the devices become robust.

In example 3 of the architecture, the communication device 100 includes a device-dependent unit 110 and a device-independent application unit 130. The device-dependent section 110 includes hardware sections 111 and 112 that depend on a compliant standard or a device manufacturing vendor, and software sections 113 such as drivers and firmware that drive the hardware sections 111 and 112. The driver or the like hides the difference in the device-dependent unit 110.

It includes a functional unit 132 and an extended function unit 131. The device-independent application unit 130 communicates between the hardware units 111 and 112 and the device-dependent software unit 113 via a driver that hides the difference between the hardware units 111 and 112 and the device-dependent software unit 113.

Information is input and output via.

Similar to the middleware unit 120 shown in FIG. 14, the basic function unit 132 inputs operation information as it is or in a predetermined format. For example, in the case of another device-independent application unit 130, it is converted into the device-independent API 22 format of the input format, and in the case of the device-dependent OAM unit, driver, firmware, and hardware unit, the input format is used. After converting to the device-independent API 22 format of the above, or after terminating and performing a predetermined process, the operation information is input. At the time of input, it is desirable to delete unnecessary input information at each input destination, and if there is insufficient information, it is desirable to collect and supplement it via other device-independent API 22 or device-independent API 27.

For example, when the extension function unit 131 is used for multicast service and power saving support according to the service request, the extension function unit 131 is added as needed when it is needed, and deleted as needed when it is no longer needed. However, it may be replaced or changed according to the change.

It is required to comply with the provisions of 987.3) and the like. As an example of the division of functions, the real-time clock itself is the device-dependent unit 110, and the time adjustment calculation to the host device can be processed by the application (it can also be the device-dependent unit 110 depending on the accuracy).

In this main function, forced switching is required to comply with regulations such as 50 milliseconds or less. As an example of the division of functions, it is also possible to perform processing by the application except for hardware switching trigger detection and switching processing such as failure detection. When the switching trigger is detected and the instruction is given to (from) the EMS140 side without setting the redundant path in advance, it depends on the device.

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, or other functions may be provided. You may. In addition, the evaluation of whether or not each function can be softened is an example on the premise that the processing capacity of the OLT expected in 2018 and the application of the soft switch are not assumed. It may be changed as appropriate assuming the assumed processing capacity and application of the soft switch. The function may or may not be softened. The internal configuration of each function may be another configuration as long as the same function can be realized.

The main softening area is the algorithm included in the eight main functions. The function in the softened area is the device-independent application unit 130 on the device-independent APIs 21 and 22. For example, the algorithms in the ONU registration or authentication function, the DWBA function, the setting / management / monitoring control function, and the power saving control function that contribute to the differentiation service are treated as the extension function unit 131 in the device-independent application unit 130. The MLD proxy app includes a multicast function.

The extended function unit 131 is used as the extended function unit 131 according to the importance such as the frequency of updating functions and the realization of original specifications in the application. Those with low update frequency or low demand for realization of original specifications are preferably middleware units 120 other than the basic function unit 132 and device-independent application unit 130, and device-dependent software and hardware units 111 and 112. In particular, it is preferable that the functions having a limitation due to the processing capacity of the software are left as the hardware units 111 and 112. For example, priority processing of the main signal and functions such as DBA that improve line utilization efficiency or contribute to service differentiation, and management that is closely related to the business flow of the operator and requires unique specifications for each operator. From the control function to the extended function unit 131.

Further, although centralized control by the CPU is assumed, the applications of each classified group may be distributed and arranged in each package (Cont, OSU, SW). Further, 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 FIG. 31 may be a part of the EMS-IF, or may be equivalent to the device-dependent API 25 in FIG. Further, although the processing of the application is performed on the CPU, some or all of the processing may be performed on an alternative device having a processing function, for example, a processor other than the CPU, such as a GPU, NPU, DSP, or an FPGA. The same applies to other embodiments.

The application processes on a server or the like, and after transmitting the processing result on the transmission line in a format that can be transmitted on the transmission line such as an Ethernet (registered trademark) frame, the application arrives at the OLT. Here, the format that can be transmitted on the transmission line may be a frame other than an Ethernet (registered trademark) frame or transmission of TDM or the like, and although it is via a converter (CONV. In FIG. 32), OSU, SW, or If the λ card can receive the processing result of the application without going through the converter, the converter is unnecessary.

In the examples of FIGS. 14 and 15, the softened area is the basic function unit 132, the management / control agent unit 133, the extended function unit 131, and the middleware unit 120, but the softened area is the service adaptation (encryption). , Fragment processing, GEM (GPON Encapsulation Method) framing) / XGEM (XGPON Encapsulation Method) framing) X, PHY adaptation FEC, scramble, synchronous block generation / extraction, GTC (GPON Transmission Convergence) framing, PHY framing , SP conversion, and encoding method may also be targeted. An implementation example of the softening function of the architecture and an example of function deployment corresponding to the hardware units 111 and 112 will be described. The function deployment includes, for example, a softening function in a network device or an external server.

Assume an OLT including a plurality of OSUs, switches, information processing units, and control units. Each OSU has a different transmitter / receiver for each wavelength. In this case, the middleware unit 120 is mounted on each OSU and the switch, and the softened area such as the device-independent application unit 130 is mounted on the information processing unit.

The information processing unit, that is, the CPU executes the device-independent application unit 130. The device-independent application unit 130 includes an extended function unit 131 for the OSU, an extended function unit 131 for the switch, and an extended function unit 131 for the control unit. The extended function unit 131 for OSU is, for example, a power saving application, a protection application, a DBA application, and an ONU registration authentication application. The extended function unit 131 for the switch is, for example, an MLD proxy application. The extended function unit 131 for the control unit is, for example, a low-speed monitoring application (OMCI), a low-speed monitoring application (EMS-IF (InterFace), and a setting / management application. The EMS 140 is, for example, an OSS (Operation Support System). ..

G. In the case of 989.3, for example, it becomes as shown in FIGS. 30, 33 to 35. In the case of the DBA application, the middleware unit 120 shown in FIGS. 14 and 15 or the basic function unit 132 shown in FIGS. 16 and 17 operates the embedded OAM engine which is the hardware units 111 and 112 of the TC layer. Let me. Then, the transmission / reception units, which are the hardware units 111 and 112 of the PMD layer, receive according to the DBA application. If the transmitter / receiver receives an uplink signal that does not follow the DBA, it may not follow the DBA application.

The information processing unit is not limited to these softening functions, and may have other softening functions. The hardware units 111 and 112 are 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 the transmission / reception unit, the OSU, the switch, and the control unit. Further, as shown in FIG. 18, a proxy unit or an external server that processes signals input / output to / from the switch may be provided on the NNI (Network-Network Interface) side of the switch. The external server may be an information processing function called a so-called cloud such as a data center equipped with a plurality of devices.

Each function may be appropriately arranged according to the demand for processing capacity and processing delay. Further, the OSU may be provided with a switch unit 12 or a switch unit 13, or may be provided with a switch (switch unit 12 when the switch unit 13 is provided) separately from the switch. It is desirable that the functions of the switches are appropriately shared between the switch unit 12 and the switch unit 13 according to the processing capacity of the switch without overlapping, but they may overlap.

The place where the softening function is deployed is not limited to the information processing unit, and may be placed in a place where a plurality of arithmetic operations can be performed. For example, the places where the software function is deployed are other than the transmission / reception unit, OSU switch, OSU switch, OLT control unit, OLT switch, OLT information processing unit, OLT switch, control unit, and information processing unit. It may be either a proxy unit that processes signals input / output to / from the switch on the NNI side of the switch, or a processing device such as an external server.

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

Other than the ONU switch, such as the transmitter / receiver, the OSU transceiver and other than the switch, the OLT switch, the OLT control unit, the OLT information processing unit, the other OLT, the OLT. It may be deployed to somewhere such as a proxy unit, an external server, etc. on the main signal path outside of the above, or to a combination of a plurality of deployment locations. Other than the OLT switch, for example, the transmitter / receiver, the OSU switch, the OSU transceiver and other than the switch, the OLT control unit, the OLT information processing unit, the other OLT, the OLT. It may be deployed to somewhere such as a proxy unit, an external server, etc. on the main signal path outside of the above, or to a combination of a plurality of deployment locations.

Further, the location where the softening function is deployed may be appropriately changed according to the deployment status of the extension function unit 131, the computing capacity of the computing location, the computing load, the power consumption, and the like.

The main functions related to the main signal processing of the OLT and the relationships between the functions will be described. Transfer the OLT function to the switch. A PON main signal processing function that performs 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 ONU registration or authentication function, DBA control function, and DWA function are provided in the information processing unit. The switch is provided with L2 main signal processing functions such as VLAN control used in framing, priority control in the previous stage of the shaper, max or demax (MuX / Dmax) and queue (Queue), and shaper in the previous stage of framing.

Deploy the multicast function such as the copy function in the previous stage of the shaper and the MLD (Multicast Listener Discover) proxy used for copying to the switch. In this way, by deploying the PON main signal processing function and the PON access control function deployed in the PON to the switch, the PON basic function unit 132 is reduced. In particular, it is preferable to avoid duplication of the L2 main signal processing and deploy it in the switch.

It should be noted that the switch functions are illustrated on the premise that Classifier, Modifier, Policer / Shaper, Cross Connect, Queue, and Scheduler are provided in this order. However, it may be changed as appropriate. For example, in the uplink direction, if processing is not performed within the bandwidth allocation unit, the input from the ONU is PON by removing the preamble and burst overhead for burst transmission, decapsulating the frame, and removing the LLID. All the functions of Classifier, Modifier, Policer / Shiper, Cross Connect, Queue, and Scheduler may be performed by the switch, or only Modifier, Cross Connect, Queue, and Scheduler may be performed by the switch.

Further, if a VID (Virtual LAN Identifier) or the like that describes a path or the like after the PON termination is given by the ONU, Cross Connect, Queue, and Scheduler may be used. If the upper network can be regarded as a single path, Queue and Scheduler may be used. Further, if the DBA is performed so that the frames do not collide with the Cross Connect, it can be a Classifier, a Modifier, a Policer / Sharper, or a CrossConnect. Furthermore, if processing is not performed in the bandwidth allocation unit in the upstream direction, the input from the ONU is removed from the preamble and burst overhead for burst transmission, the frame is decapsulated, and the LLID is removed to PON. Is only terminated, and if a VID or the like that describes the path or the like after the PON termination is given by the ONU, only the Cross Connect can be used.

Further, in Classifier, Modifier, Policer / Sharper, CrossConnect, Queue, and Scheduler, Classifer, Policer / Sharper, Modifier, CrossConnect, Queue, and Queue may be placed in front of the quer, Queue, and Queue. It may be a Modifier, Queue, Policer / Shiper, Cross Connect, Scheduler, or it may be a Classifer, Queue, Policeer / Queue, Modifier, Cross Connect, Scheduler. Considering the burst transmission of PON, unnecessary police / shipping due to burst property caused by multiplexing priority traffic such as multicast, and the reception of leveled traffic on the receiving side, the police / skiper It is desirable to execute the processing by Police / Shipping after placing a Queue in the previous stage and leveling it.

As described above, the communication device 100-1 includes a storage control unit 141-1 and a device control unit 142-1. The storage control unit 141-1 stores the operation information (state information) of the OSU package unit 101-1 and the like of the communication device 100-1 in the memory 220 of the storage device 200. The device control unit 142-1 acquires the operation information of the OSU package unit 101-2 of the communication device 100-2 stored in the memory 220 by the communication device 100-2. The device control unit 142-1 operates the OSU package unit 101-1 and the like of the communication device 100-1 based on the operation information of the OSU package unit 101-2 and the like of the communication device 100-2.

With this configuration, the storage control unit 141-1 connects the communication device 100-1 to the memory 220 of the storage device 200 that does not transition to the specific state even when the state of the communication device 100 transitions to a specific state (sleep state, etc.). Stores the operation information of the device.

As a result, when the communication device 100-1 inherits the operation information held by the communication device 100-1 whose state transitions, the communication device 100-1 transitions to a specific state (sleep state, etc.). It is possible to shorten the time until it is done.

At the time of state transition to a specific state, the main body such as sleep operation (execution unit), the operation information of the main body such as sleep operation (device included in the communication device 100) is externally independent of the main body such as sleep operation. By storing it in, it is possible to inherit the operation. The specific states are, for example, a sleep state, a switching state of the operational communication device 100, a user accommodation switching state, and a multicast state. Since the operation information is held outside the communication device 100, it is possible to prevent the inheritance of the sleep operation and the like from being lost when switching to another communication device 100. The communication device 100 can ensure the inheritance of the information held by the device.

Further, by diverting a normal general-purpose or softwareized switch as an execution unit, it is possible to realize an OLT capable of inexpensively, flexibly and quickly adding functions of a general-purpose or softwareized switch.

As shown above, in the first embodiment, by separately arranging the instruction unit and the execution unit, the inheritance of the information held by the device can be changed without lengthening the time required for sleep, switching, and user / accommodation change. Make it possible.

The configuration according to the first embodiment shown above is the same in the following embodiments, and may be combined as appropriate. For example, FIG. 14 illustrates a case where the execution unit is composed of only the transmission / reception unit 11 (TRx), the switch unit 12 and the switch unit 13, but the transmission / reception unit 11 (TRx), the switch unit 12 and the switch unit A place other than 13, a place other than that, a place where the PON is terminated, or a control unit 14 may be used as an execution unit.

Is.

(Embodiment 1-3)
Although the configuration used for TWDM-PON is illustrated in the first embodiment, it may be applied to WDM-PON. The embodiment 1-3 is the embodiment 1-1, except that the WDM-PON does not have to have a function of time-dividing and multiplexing the band resources of the PON section of the ONU-OLT between ONUs such as DBA. Is similar to.

(Embodiment 1-4)
Combination including OFDM ()-PON, CDM-PON, SCM-PON, and core wire division multiplexing In Embodiment 1-1, the configuration used for TWDM-PON was illustrated, but for PON that shares resources other than wavelength and time. It may be applied. For example, OFDM (orthogonal frequency-division multiplex) -PON that divides and multiplexes the frequency resources of electricity of one wavelength, SCM (Subcarrier Multiplexing) -PON that divides and multiplexes the frequency resources of electricity of one wavelength, and CDM that divides and multiplexes by a code. It may be applied to Code Division Multiplex) -PON, core wire division multiplexing may be used in combination, spatial division multiplexing using multi-core fiber or the like may be used in combination, or wavelength division multiplexing may not be used. good. The same applies if the function of dividing and multiplexing the wavelength resources of the TWDM-PON by wavelength division multiplexing is read as a function corresponding to the function required for dividing and multiplexing each of the multiplexed resources.

(Embodiment 2)
In Embodiment 2, the configuration used for TWDM-PON performs GEM encapsulation. In this case, the switch is provided with an adapter that generates a GEM frame so that the GEM frame is conducted between the switch and other parts. By transferring the GEM encapsulation to the switch, the L2 functional part can be excluded from the protocol stack of the other part, and the overlap of the L2 functional part can be avoided in the switch and the other part.

Although TWDM-PON is taken as an example, if the frame for identification in the PON section is handled in the same manner as in the first to second embodiments to the first to fourth embodiments, the same applies to other PONs. The effect of is obtained. For example, in the case of IEEE standard GE-PON, 10GE-PON, etc., instead of the GEM frame, an LLID may be added so that the frame to which the LLID is given conducts between the switch and other parts. good.

(Embodiment 3)
In the third embodiment, the control information used for the TWDM-PON goes through the switch. In this case, instead of transferring the bridge function-related to the switch, any one of PLOAM, Embedded OAM, and OMCI that retains control information is framed as necessary and processed via the switch. By inputting and outputting control information via the switch, there is an effect that processing other than the switch becomes lighter. In addition to the transfer of the third embodiment, the transfer of the bridge function of the first and second embodiments may be performed.

Although TWDM-PON is taken as an example, if the control information is handled in the same manner and processed via the switch, the same applies to other PONs as in the first to second embodiments of the first to fourth embodiments. The effect is obtained.
