(Embodiment 1)
FIG. 1 is a diagram illustrating a configuration example of a response device 1 according to the present embodiment. In FIG. 1, only functional blocks related to the present embodiment are extracted and shown. The response device 1 includes a command input unit 2 that inputs a setting management command transmitted from a controller or the like, and a response unit 3 that outputs a response based on the input setting management command. Here, the setting management command is an instruction for executing processing related to setting management.

Hereinafter, the processing performed by the response device 1 will be described by exemplifying a plurality of operation examples (first operation example to sixth operation example).
(First operation example)
In the first operation example, the response unit 3 outputs a response to the setting management command of the device of the type to be controlled indicated by the setting management command to the control device based on the setting management command transmitted from the control device such as the controller. Then, the value indicated by the setting management command is converted into a value corresponding to the device of the control target type and set in the device of the control target type. In the following description, a type of device to be controlled is referred to as a control target device. The response unit 3 may identify the type to be controlled based on information input in advance by the control device, or may be a MIB (Management Information Base) or YANG (Yet Another Next Generation) corresponding to a setting management command. Or the order of arrival with the setting management command or the order of commands corresponding to the response from the device to the setting management command. Note that the response unit 3 does not need to identify the type itself when creating a response or inputting a response separately based on a response from the control device to a response to a setting management command from the control device described later.

  The response of the type of device to be controlled (control target device) may be ported to the response device 1 of the type of device itself or created in response to a response to the setting management command from the control device. Alternatively, it may be set as a combination of a character string and a numerical value according to a separate control device. In the first operation example, as viewed from the control device, a device that conforms to the IEEE (Institut of Electrical and Electronics Engineers) standard is used as an ITU-T (International Telecommunication Union Standard Control device). can do.

  For example, when a setting management command related to an LLID (Logical Link ID), a MAC address, or the like is input to the command input unit 2, the response unit 3 sends a value indicated by the setting management command to the control device that is the transmission source of the setting management command. A response indicating that it has been set is output, and the control target device is set by converting it into an ONU-ID, Alloc-ID, T-CONT number, etc., which are values that the control target device can handle. . If the settings management command does not have enough settings for the control target device, it will be supplemented.

An example of conversion is shown below.
-ONU serial number-> ONU serial number-Control package setting-> Alert notification destination (OSS-IF) IPv4 address setting-Control target PON-IF package registration-> PON-IF package registration linked with control package-Control target PON-IF Delete package → Delete PON-IF package linked with control package ・ Display PON-IF package information → Display PON-IF package information ・ Activate PON-IF package → Activate PON-IF package or power on OSU sub board
・ Stop PON-IF package → Stop PON-IF package or turn off OSU sub board power
・ Authenticated ONU information display → Authenticated ONU information display ・ Authentication target ONU registration → Authentication target ONU registration (however, registration is the ONU serial number)
-Authentication target ONU deletion-> Authentication target ONU display-Authentication target ONU display-> Authentication target ONU display-Alarm information output-> Alarm history information output-> History information output-> Command and command response history information output

  These processes may be provided as a FASA application setting management application, or may be provided on the FASA platform.

(Second operation example)
In the second operation example, the response device 1 accumulates the setting management commands transmitted from the control device, and sets the control target device after the value to be set first is input on the control target device side. To do. Specifically, when the setting order of the setting management command transmitted from the control device is different from the setting order of the control target device set by the setting management command suitable for the control target device, the response device 1 The setting on the control target device is suspended until the value to be set first is set on the device side. And after the value which should be set first by the control object apparatus side is input, the response apparatus 1 sets in order from the value which should be set first by the control object apparatus. With such a configuration, it is possible to cope with devices having different setting orders.

(Third operation example)
In the third operation example, the response device 1 responds to the setting management command transmitted from the control device with a provisional value. In the third operation example, the response device 1 is different from the setting order of the setting management command transmitted from the control device and the setting order of the control target device set by the setting management command suitable for the control target device, and It is also possible to deal with a case where the control device is waiting for a response to the setting management command. Specifically, the response unit 3 sets a temporary value in the control target device, and outputs a response obtained by setting the temporary value to the control device. The provisional value is preferably a value according to a predetermined rule when a value assumed in the setting or response of the control target device or the setting or response of the control device follows a predetermined rule. For example, if the value is a value that sequentially adds a predetermined value to the initial value, the value is a value that sequentially subtracts the predetermined value from the initial value, that value if the value is generated by a random number generation formula, If it is the same value as the previously deleted setting, it is that value. In the second operation example, it is not necessary to create a response by the response unit 3, so that the load can be reduced.

(Fourth operation example)
In the fourth operation example, the response device 1 accumulates the setting management command transmitted from the control device, and when the control device is waiting for a response to the setting management command, the response device 1 uses a temporary value for the setting management command. In response, the setting to the control target device is suspended until the value to be set first on the control target device side is set, and after the value to be set first on the control target device side is input, Set in order from the value to be set first. Specifically, the response unit 3 holds the value to be set without setting the control target device until all the values to be set for the control target device are received, and if the value to be set is not input from the control device. Then, a response obtained by setting a temporary value in the control target device is output to the control device. Here, if all previous settings in their own order are received, they may be output. The response unit 3 receives all the values to be set in the control target device and then sets them in the control target device. It is desirable that the provisional value is a value that can be set on the control target device side. The provisional value is the same as the value shown in the third operation example. In the fourth operation example, since the settings can be performed collectively, the load on the control target device can be reduced.

(Fifth operation example)
In the fifth operation example, the response device 1 stores the setting management command transmitted from the control device, and when the control device is waiting for a response to the setting management command, the response device 1 uses a temporary value for the setting management command. In response, the setting to the control target device is suspended until the value to be set first on the control target device side is set, and after the value to be set first on the control target device side is input, It sets in order from the value that should be set first, and corrects the response related to the provisional value to a true value or a value that should correspond to the true value. Specifically, when the response unit 3 obtains the true value or the value corresponding to the true value after the provisional value is set, the response unit 3 sets the obtained true value or the value corresponding to the true value to be controlled. The provisional value is corrected by resetting the device and outputting the response obtained by the resetting to the control device. In the fifth operation example, it is possible to cope with the case where the provisional value is set to a value outside the control target or ONU (VLAN ID). Here, the true value is a correct value as a value to be set for the control target device.

(Sixth operation example)
In the sixth operation example, the response device 1 stores the setting management command transmitted from the control device, and when the control device is waiting for a response to the setting management command, the response device 1 uses a temporary value for the setting management command. In response, the setting to the control target device is suspended until the value to be set first on the control target device side is set, and after the value to be set first on the control target device side is input, The values are set in order from the value to be set first, and the setting relating to the temporary value is temporarily dropped and reset. The sixth operation example is particularly suitable when the value of the previous registration can be used for re-registration.

Next, another process performed by the response device 1 will be described by illustrating a plurality of operation examples.
(First operation example)
In the first operation example, the response unit 3 converts the response to the setting management command of the control target device indicated by the setting management command based on the setting management command transmitted from the control device, and outputs the response to the control device. Then, a value indicated by the setting management command is set in the control target device to a value corresponding to the control target device.

(Example of second operation)
In the second example of operation, the response device 1 stores the setting management command transmitted from the control device, and after the value to be responded first on the control device side is input or after the response is received, the control device To respond to. Specifically, when the setting order of the setting management command transmitted from the control apparatus is different from the setting order of the control target apparatus set by the setting management command suitable for the control target apparatus, the response apparatus 1 The response to the control device is held until a value to be previously responded is set or until a response is made. And the response apparatus 1 responds in an order from the value which should respond first by the control apparatus, after the value which should respond first by the control object apparatus side is responded. With such a configuration, it is possible to cope with devices having different setting orders.

(Example of fourth operation)
In the fourth example operation, the response device 1 accumulates responses from the device to be controlled, and sets the setting management command as a temporary value when the setting management command is waiting for the device to be controlled. , Hold the response to the control device until the value to be responded first on the control device side, and after setting the value to be set first on the control device side, from the value to be responded first on the control device Answer in order. Specifically, the response unit 3 holds the value to be responded without responding to the control device until all the values to be responded to the control device are responded, and the value to be responded from the device to be controlled must be input. For example, the setting obtained by responding to the control device with a provisional value is output to the device to be controlled. Here, it may be output when all previous responses in their own order have been received. The response unit 3 receives all the values to be set in the control target device and then sets them in the control target device. It is desirable that the provisional value is a value that can respond to the control device side. The provisional value is the same as the value shown in the third operation example. In the fourth operation example, since responses can be performed collectively, the load on the control device can be reduced.

(Example of 5th operation)
In the fifth example of operation, the response device 1 stores the response of the setting management command returned from the control target device, and when the control target device is waiting for the setting management command, the setting management command is stored. Set the command with a temporary value, hold the response to the control device until the value that should be responded first on the control device side, and after the value that should be responded first on the control device side is input, In this order, the values that should be responded first are set in order, and the setting relating to the temporary value is corrected to a true value or a value that should correspond to the true value. Specifically, when the response unit 3 obtains a true value or a value that should correspond to the true value after the provisional value response, the controller 3 determines the obtained true value or the value that should correspond to the true value. And the provisional value is corrected by outputting the setting obtained by the re-response to the device to be controlled. The fifth example of operation can deal with the case where the provisional value response is a value such as the outside of the control target or ONU (VLAN ID). Here, the true value is a correct value as a value to be responded to the control device.

(Example of 6th operation)
In the sixth example of operation, the response device 1 stores the response of the setting management command transmitted from the control device. When the control target device is waiting for the setting management command, the response management device 1 Set a temporary value, hold the response to the control device until the value to be responded first on the control device side, and after the value to be responded first on the control device side is input, In order from the value that should be responded to, the response related to the provisional value is temporarily dropped and re-answered. The sixth example of operation is particularly suitable when the value of the previous response can be used in the case of re-response.

  In the above example, when an instruction is given to an apparatus or a component that constitutes a group of devices inside the apparatus or a virtual group, the instruction may be given as instructions from a plurality of control apparatuses. This is suitable for a system configured to instruct from a different control device for each control content. When responding to the control device or the like, it may respond as a plurality of devices. This is the case when the control device or the like instructs the communication device including the response device 1 of the present application as a plurality of communication devices of different types or the like, or when simulating a plurality of virtual devices Suitable for.

  Although the response device 1 has been described above, the response device 1 may include software instead of hardware, a FASA application, a FASA platform, an extended function unit, a basic function unit, a management / control agent unit, or the like. Alternatively, a middleware unit, a device-independent application unit, a device-dependent application unit, or the like may be used.

  The communication device including the response device 1 is a communication device that performs communication with another communication device by a signal such as an optical signal passing through a communication network such as an optical fiber network such as PON. This communication apparatus is, for example, an OLT (Optical Line Terminal). The communication device may be, for example, an OSU (Optical Subscriber Unit). The communication device may be, for example, a combination of an OLT that includes or does not include a switch unit (SW) that switches an optical signal and another switch unit (SW). The communication device may be, for example, a combination of OLT and ONU (Optical Network Unit). The communication device may include a plurality of devices. Moreover, other communication apparatuses, such as ONU, MUX (multiplexer), DEMUX (demultiplexer), and a switch, may be sufficient.

  Next, as an example, the operation and the like are illustrated on the assumption that the communication apparatus is a PON OLT conforming to the ITU-T recommendation, such as a TWDM (Time and Wavelength Division Multiplex) -PON system. Here, although TWDM-PON is used, the PON may be a PON other than the TWDM-PON compliant with the ITU-T recommendation. For example, the PON may be a PON conforming to an IEEE standard such as GE (Gigabit Ethernet (registered trademark))-PON, 10 GE-PON, or the like. A TC (Transmission Convergence) layer and a PMD (Physical Medium Dependent) layer are the same if they are read as corresponding layers in the standard.

  The communication apparatus includes hardware or software, or a combination of them or a componentized function. For example, the communication device is software realized by using a general-purpose input / output interface (for example, FASA (Flexible Access System Architecture) application API) that has different functions for each service or each carrier. An access network that provides functions that do not need to be changed according to services or requests because the application is a component (for example, FASA application) and the input / output interface that is generalized to the application is provided and is standardized Device infrastructure components (eg, FASA infrastructure). Here, by using a generalized input / output interface, it is possible to easily add and replace functions, and flexibly and quickly provide services with various requirements. In this specification, an application is also referred to as an “app”.

  For example, the communication between the components is performed via the middleware unit 120 described later, but an original transfer path or means of the communication device 51 may be used, or OpenFlow, Netconf / YANG, or SNMP (Simple Network Management Protocol). Standardized means such as the above may be used.

  Further, the exchange between the components may be any of internal wiring, a backboard, an OAM unit, a main signal line, a dedicated wiring, an operation system, a controller, or a control panel (Cont panel). When the exchange between components is directly terminated and input, it may be encapsulated in an OAM unit or a main signal. Interchange between components may be terminated at any point and input via a route such as internal wiring, backboard, OAM unit, main signal line, dedicated wiring, operation system, controller or control panel . When using an OAM part or a main signal line, it is desirable to encapsulate the OAM part or main signal line. When the main signal line is passed, it is desirable to distribute it by the OSU or the switch part at another location.

  In this embodiment, the communication apparatus further includes an interface for receiving software components by an application such as a FASA application or a platform such as a FASA base. For example, the interface is an interface that inputs a value to be converted or supplemented and set in the control target device. For example, the interface is an interface that generates a provisional value or a provisional value. For example, the interface is an interface that notifies the type of the control target device assumed by the controller or the like. For example, the interface is an interface for notifying a response value or rule in the type of the control target device assumed by the controller or the like. For example, the interface is an interface that performs a process of correcting the provisional value. For example, the interface is an interface that designates a setting range related to the provisional value and resets the corresponding setting.

(Embodiment 1-1)
Embodiment 1-1 demonstrates the structure of the communication apparatus which comprises the communication system used for TWDM-PON. The communication device described in Embodiment 1-1 is used as a communication device including the response device 1 illustrated in FIG. Hereinafter, the first to sixth examples will be described as examples of the architecture of the communication apparatus. The architecture of the communication device constituting the communication system may be an architecture other than the first to sixth examples described below. For example, the software unit of the communication device in the first to sixth examples of the architecture may be a hardware unit.

(First example of architecture)
FIG. 2 is a diagram illustrating a first example of the architecture of the communication device. In the first example of the architecture, the communication device includes a non-generic device-dependent unit 110 whose operation depends on the device, a middleware unit 120 that conceals the hardware and software differences of the device-dependent unit 110, and the operation depends on the device. And a general-purpose device-independent application unit 130 that does not. Accordingly, the device-dependent unit 110 (vendor-dependent unit) is a functional unit that depends on the standard that the device of the communication apparatus complies with or the manufacturer of the device. In other words, the device-dependent unit 110 is not compatible with other communication devices, and cannot be used as it is for newly manufactured communication devices (particularly, devices with different standards or manufacturing vendors that conform to them). The device dependence unit 110 executes one or more functions provided in the network device.

  In addition, the device-independent application unit 130 is a functional unit that does not depend on a standard that the communication device device complies with or a device manufacturer. In other words, the device-independent application unit 130 has a high compatibility with other communication devices, and can be used as it is for a newly manufactured communication device (particularly, a device that conforms to a different standard or manufacturing vendor). Specific examples of applications provided in the device-independent application unit 130 include an application that performs setting processing in a network device, an application that performs setting change processing, and an application that performs algorithm processing.

  The middleware unit 120 and the device independent application unit 130 are connected via a device independent API 21. The device-independent API 21 is an input / output IF that does not depend on the device.

  The device dependence unit 110 includes, for example, a hardware unit 111 (PHY), a hardware unit 112 (MAC), a software unit 113, and an OAM (Operation Administration and Maintenance) unit 114. The hardware unit 111 (PHY), the hardware unit 112 (MAC), the software unit 113, the OAM unit 114, and the middleware unit 120 are connected via the device-dependent API 23. The device dependent API 23 is an input / output IF depending on the device. The device dependence unit 110 further includes an NE (Network Element) management / control unit 115. The NE management / control unit 115 and the middleware unit 120 are connected via a device-dependent API 25. The device dependent API 25 is an input / output IF depending on the device.

  What functions are the device-dependent unit 110 or the device-independent application unit 130 is derived from restrictions derived from processing for realizing the middleware unit 120 and the device-independent application unit 130, for example, the processing capability of software In addition to the restriction to be performed, it may be determined according to the update frequency of the function, the importance of the extended function, or the like. As a result, the communication device facilitates flexible and quick addition of the extended function unit (unique function unit) by the device-independent application unit 130, and can provide a communication service in a timely manner.

  For example, priority is given to a function with high update frequency, such as DBA (Dynamic Bandwidth Assignment) which improves the priority processing of the main signal and the use efficiency of the line, or a function contributing to communication service differentiation, and the device dependent unit 110 or device independent The application unit 130 may be determined. Furthermore, the device-independent application unit 130 may be used because the difference between the standards, generations, systems, systems, device types, and manufacturing vendors to which the devices to be shared are small is small.

  Even if it is not optimal for at least one of the compliant standards, generations, methods, systems, device types, or manufacturing vendors, any of the standards, generations, methods, systems, device types, or manufacturing vendor functions to comply with In order to generalize a common IF, a common IF 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, systems, systems, device types, and manufacturing vendors that the device-dependent unit 110 complies with.

  The middleware unit 120 shown in FIG. 2 and FIG. 3 described later, the driver of the device dependent unit 110 shown in FIG. 4 and FIG. 5 described later, and the device dependent application unit 150 (shown in FIG. 3 described later and FIG. 5 described later). A conversion function unit that converts IF, parameters, and the like so as to correspond to the device-dependent unit 110, and a function unit that automatically sets corresponding to insufficient IF, parameters, etc. You may prepare.

  The device dependent unit 110 illustrated in FIG. 2 includes a hardware unit 111 (PHY), a hardware unit 112 (MAC), and a software unit 113. The hardware unit 111 (PHY) executes processing from the physical layer to processing related to optical transmission / reception (PHYsical subscriber processing). The hardware unit 112 (MAC) executes a MAC (Media Access Control) process. The hardware unit 111 (PHY) and the hardware unit 112 (MAC) depend on the standard or the manufacturing vendor to which they comply. The software unit 113 executes device-dependent drivers, firmware, applications, and the like.

  In addition to these, the hardware unit 111 (PHY) and the hardware unit 112 (MAC) of the device-dependent unit 110 may include a general-purpose server, a layer 2 switch, and the like. The device dependence unit 110 may not include the hardware unit 112 (MAC). The device dependence unit 110 may not include a part of the hardware unit 111 (PHY). For example, the device-dependent unit 110 may have only light-related functions without providing low-level signal processing such as modulation / demodulation signal processing, forward error correction (FEC), codec decoding processing, and encryption processing. Good. The device dependent unit 110 may not include a PCS (PHYSICAL CODING SUBLIER) that is a part that encodes data. The device dependence unit 110 may not include a PMA (Physical Medium Attachment) and PCS that serialize data. The device dependent unit 110 may not include a PMD connected to a physical medium. When the middleware unit 120 directly drives, controls, operates, or manages the hardware unit 111 (PHY) and the hardware unit 112 (MAC) of the device-dependent unit 110 without using the software unit 113, the device-dependent unit 110 The software unit 113 may not be provided.

  The device-independent application unit 130 includes, for example, extended function units 131-1 to 131-3 (in FIG. 2, extended function A, extended function B, and extended function C), a basic function unit 132, and a management / control agent unit. 133. The management / control agent unit 133 exchanges data from an EMS (Element Management System) 140.

  In the figure, the EMS 140 and the external device 160 are connected to the device independent application unit 130 via the middleware unit 120, but the EMS 140 and the external device 160 are not necessarily connected to the device independent application unit 130 via the middleware unit 120. There is no need to do. The EMS 140 and the external device 160 may be appropriately connected to the middleware unit 120 as necessary, or may be directly connected to the device-independent application unit 130. In addition, although expressed as “connection via the middleware unit 120”, this expression is an expression from the viewpoint of the device-independent application unit 130. Actually, device-independent applications are connected to each other via the middleware unit 120 after connection by hardware.

  Hereinafter, items common to the extended function units 131-1 to 131-3 are referred to as “extended function unit 131” with a part of the reference numerals omitted. The EMS 140 is, for example, an NE controller. The device-independent application unit 130 may not include any one of the extended function unit 131, the basic function unit 132, and the management / control agent unit 133. The management / control agent unit 133 may include the basic function unit 132. Or 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 extended function unit 131, the basic function unit 132, and the management / control agent unit 133. For example, when the extended function unit 131 is unnecessary, the device-independent application unit 130 may not include the extended function unit 131. In addition, 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 unnecessarily affecting other functions. For example, the extended function unit 131 may be appropriately added, deleted, replaced, or changed when the extended function unit 131 that executes multicast service and power saving correspondence is required in accordance with 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 lower-level function unit than the middleware unit 120. When the extended function unit 131 includes the basic function unit 132, the device-independent application unit 130 may not include the basic function unit 132. When a functional unit lower than the middleware unit 120 substitutes for the basic function unit 132, the device-independent application unit 130 may not include the basic function unit 132. When the extended function unit 131 includes the basic function unit 132 and a function unit lower than the middleware unit 120 replaces the basic function unit 132, the device-independent application unit 130 may not include the basic function unit 132.

  The management / control agent unit 133 does not need to input / output from / to the EMS 140 in the case where automatic setting is performed according to a predetermined setting without receiving communication from the EMS 140. Furthermore, when the management / control agent unit 133 does not have a management setting function and the other device-independent application unit 130, the basic function unit 132, and the device-dependent unit 110 have a management setting function, the device-independent application unit 130 The management / control agent unit 133 may not be provided.

  The EMS 140 and the device-independent application unit 130 may directly input / output information. In addition, the device dependence unit 110 may be replaced by the NE management / control unit 115 and the device dependence application unit 150 (see FIG. 3 described later and FIG. 5 described later) as a lower-level functional unit of the NE management / control unit 115. Good.

  The management / control agent unit 133 does not need to input / output information to / from the EMS 140 when performing automatic setting according to a predetermined setting. Further, when the management / control agent unit 133 does not include the management setting function and the other device-independent application unit 130, the basic function unit 132, and the device-dependent unit 110 have the management setting function, the device-independent application unit 130 The control agent unit 133 may not be provided. The EMS 140 and the device-independent application unit 130 may directly input / output information.

Examples of input / output between the device-independent application unit 130 and the device-dependent unit 110 are as follows.
For example, the DBA application unit and the protection application unit mutually input / output information from / to the TC layer embedded OAM engine (Embedded OAM Engine). A Dynamic Wavelength and Bandwidth Assignment (DWBA) application and an ONU registration / authentication application unit input / output information to / from the TC layer PLOAM engine. The power saving application unit inputs and outputs information to and from the OMCI and L2 main signal processing function unit (L2 function unit). An 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 / outputs information to / from the OMCI. The OMCI and L2 function units operate XGEM framer (XGPON Encapsulation Method Framer) and encryption. Here, DWBA and DBA may be separate, integrated, or combined. For example, the management / control agent unit 133 is an application unit for a maintenance operation function, and inputs / outputs information to / from the EMS 140 such as an NE controller for the NE management / control unit 115.

  Note that the device-independent application unit 130 may be prioritized. For example, the management / control agent unit 133 is the first priority with the highest priority. 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 unit 130 includes a device vendor, a method, a device type, a device generation, for example, ITU-TG. TWDM-PON 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 without depending on any of B (Broadband) PON conforming to the 983 series. The device-independent application unit 130 is different from a device vendor, a method, a device type, a device generation, for example, 10GE-PON conforming to IEEE802.3av or IEEE1904.1 and GE-PON conforming to IEEE802.3ah. It is an application that works regardless of whether

  As an application of the extended function unit 131, only an application for driving functions provided for some vendors, methods, types, and generations, and devices of some vendors, methods, types, and generations via the device-independent API 21. The application which drives the function with which it prepares may be included.

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

  The middleware unit 120 inputs and outputs information via the device-independent application unit 130 and the device-independent API 21. The middleware unit 120 inputs and outputs information to and from the OAM unit 114, the driver, the firmware, the hardware unit 111 (PHY), or the hardware unit 112 (MAC) 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 unit of the device-independent application unit 130, the middleware unit 120 converts the information into the input format of each unit of the device-independent API 21. If the output destination is the OAM unit 114 of the device dependent unit 110, the driver, firmware, the hardware unit 111 (PHY), or the hardware unit 112 (MAC), the middleware unit 120 has the device dependent API 23 of the format to be input to each. The information is transmitted to the output destination after being converted into a format or after being terminated and subjected to predetermined processing.

  When inputting, the middleware unit 120 deletes unnecessary input information at each input destination, and if there is insufficient information, the middleware unit 120 can collect and supplement via the other device-independent API 21 or the device-dependent API 23. desirable. In addition, at the time of input to the middleware unit 120, it may be broadcast or multicast and broadcast to related applications or the like.

  In FIG. 2, the middleware unit 120 and the device-dependent unit 110 are illustrated as a single unit, but may be configured by 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 using inter-processor communication or the like across the processors and hardware. The device-independent application units 130 and the device-independent application units 130 may be arranged on a user space on a single processor as an execution program such as DLL (Dynamic Link Library) or on a plurality of processors. You may arrange | position on user space.

The device-independent application unit 130 may be arranged in the kernel space after securing an input / output IF such as an API, or may be arranged together with the middleware unit 120 having an IF 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 the kernel space may be arbitrarily combined 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, either may be selected by switching, both may be processed in cooperation, or actual processing may be performed by only one of them. The same applies to the software of the device dependent unit 110.

  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 in which the device-dependent application unit 150 (see FIG. 3 to be described later and FIG. 5 to be described later) is arranged is also effective from the viewpoint of the influence on other programs due to the restriction of the bus and the speed due to the inter-processor communication and the occupation of the communication path. It is desirable to arrange in the user space, kernel space, or firmware of the processor that performs processing or in the vicinity of the processor. 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 advance in the middleware unit 120 assuming the extended function unit 131 to be added. However, the device-independent API 21 is necessary in a form that suppresses modification of the device-dependent API 23 and other device-independent application units 130. It may be added or deleted accordingly.

  In this example, the software area is the basic function section 132, the management / control agent section 133, the extended function section 131, and the middleware section 120. However, the software area is a service adaptation (encryption, fragment processing, GEM). Framing / XGEM framing, PHY adaptation FEC, scramble, synchronization block generation / extraction, GTC (GPON Transmission Convergences) framing, PHY framing, SP conversion, and coding method may also be targeted. An example of implementation of the function and an example of function deployment corresponding to the hardware unit will be described, for example, the function deployment includes a software function in a network device or an external server, which is the same in other examples.

(Second example of architecture)
FIG. 3 is a diagram illustrating a second example of the architecture of the communication device. In FIG. 3, the communication device is configured to further include a device-dependent application unit 150 under the middleware unit 120 of the communication device illustrated in FIG. 2. The second example of the architecture is the same as the first example of the architecture except that the device-dependent application unit 150 is provided.

The device-dependent application unit 150 and the management / control agent unit 133 are connected by the API 26.

  The device-independent application unit 130 includes, for example, a management / control agent unit 133 that receives communication from the EMS 140, a basic function unit 132, and an extended function unit 131. The device-independent application unit 130 may not include any of the management / control agent unit 133, the basic function unit 132, and the extended function unit 131, as in the first example of the architecture. The device-independent application unit 130 may further include a function unit other than the management / control agent unit 133, the basic function unit 132, and the extended function unit 131. Moreover, it is preferable that the extended function unit 131 can be added, deleted, replaced, or changed without affecting other functions as in the first example of the architecture.

  The basic function unit 132 may be included as a part of each extended function unit 131, or may be substituted below the middleware unit 120.

It does not have to be.

  In addition, a part of the basic function unit 132 may be replaced with a device-dependent application unit 150 that is a lower level of the middleware unit 120. The management / control agent unit 133 does not need to input / output information to / from the EMS 140 when performing automatic setting according to a predetermined setting. Further, when the management / control agent unit 133 does not include the management setting function and the other device-independent application unit 130, the basic function unit 132, and the device-dependent unit 110 have the management setting function, the device-independent application unit 130 The management / control agent unit 133 may not be provided.

  The EMS 140 and the device-independent application unit 130 may directly input / output. When the lower part of the middleware unit 120 replaces the basic function unit 132, the device-independent application unit 130 may not include the basic function unit 132.

  In the communication apparatus shown in FIG. 3, the device-dependent application unit 150 may input / output information via the middleware unit 120, may directly input / output information from the management / control agent unit 133, Information may be input / output to / from any of these, or directly to / from the EMS 140. In addition, when the device-dependent application unit 150 is automatically set according to a predetermined setting without receiving communication from the EMS 140, and management and control information can be acquired from the EMS 140 via the middleware unit 120, The independent application unit 130 may not include the management / control agent unit 133.

  The device-independent application unit 130 inputs information via the middleware unit 120 at least between the hardware unit 111 (PHY) and the hardware unit 112 (MAC) of the device-dependent unit 110 or between the software unit 113. Output. The device independent application unit 130 inputs and outputs to / from each other via the middleware unit 120 as necessary. In particular, when the device-independent application unit 130 performs control or management according to information input / output with the EMS 140, the device-independent application unit 130 receives information from the management / control agent unit 133 that receives communication from the EMS 140. Input and output.

  The NE management / control unit 115 inputs / outputs NE management information and control information to / from the management / control agent unit 133 via the middleware unit 120. The NE management / control unit 115 may directly input / output NE management information and control information to / from the EMS 140 without using the middleware unit 120.

  The device-dependent application unit 150 inputs and outputs NE management information and control information to and from the management / control agent unit 133. The device-dependent application unit 150 may directly input / output information to / from the EMS 140 without using the management / control agent unit 133. The management / control agent unit 133 inputs and outputs information between the EMS 140, the middleware unit 120, and the device-dependent application unit 150. The middleware unit 120 inputs and outputs NE management information and control information to and from the NE management / control unit 115.

  The NE management / control unit 115 may directly input / output NE management information and control information to / from the EMS 140 without using the middleware unit 120. The middleware unit 120 inputs / outputs information to / from the device-independent application unit 130 via the device-independent API 21, and the OAM unit 114, driver, firmware, hardware unit 111 (PHY) of the device-dependent unit 110, and Information is input / output to / from the hardware unit 112 (MAC) via the device-dependent API 23.

  The middleware unit 120 shown in FIG. 3 inputs as it is or in a predetermined format, like the middleware unit 120 shown in FIG. 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 later, but the device-dependent API 23 and other device-independent application units 130 may be modified as necessary. It may be added or deleted in a suppressed manner.

(Third example of architecture)
FIG. 4 is a diagram illustrating a third example of the architecture of the communication device. In FIG. 4, instead of the middleware unit 120 described in the first example of the architecture illustrated in FIG. 2, the basic function unit 132 includes a hardware unit 111 (PHY), a hardware unit 112 (MAC), and an extended function unit 131. Input and output. The other device-independent application unit 130 is the same as the first example of the architecture.

  In the figure, the EMS 140 and the external device 160 are connected to the device independent application unit 130 via the basic function unit 132. However, the EMS 140 and the external device 160 are not necessarily connected to the device independent application unit 130 via the basic function unit 132. It is not necessary to connect to the unit 130. The EMS 140 and the external device 160 may be appropriately connected to the middleware unit 120 as necessary, or may be directly connected to the device-independent application unit 130. In addition, although expressed as “connection via the middleware unit 120”, this expression is an expression from the viewpoint of the device-independent application unit 130. Actually, device-independent applications are connected to each other via the middleware unit 120 after connection by hardware.

  Compared to the first example of the architecture, the third example uses a middleware unit 120 including the device-dependent APIs 23 and 25 for each device in which at least one of the conforming standard, generation, method, system, device type, and manufacturing vendor differs. There is no need to create it. As a result, the communication device of the third example of the architecture is advantageous in that more functions can be generalized and ported between the generations between apparatuses, the connectivity can be easily verified, and the functions of the apparatuses become robust.

  The communication device according to the third example of the architecture includes a device-dependent unit 110 and a device-independent application unit 130. The device dependent unit 110 includes a hardware unit 111 (PHY) and a hardware unit 112 (MAC) that depend on a compliant standard or a device manufacturing vendor, etc., and a hardware unit 111 (PHY) and a hardware unit 112 (MAC). And a software unit 113 such as a driver and firmware for driving the computer. The driver or the like hides the difference of the device dependence unit 110.

  The device-independent application unit 130 includes an extended function unit 131 and a basic function unit 132. The basic function unit 132 uses a device-independent API 27 (porting IF) via a driver that hides the difference between the hardware unit 111 (PHY) and the hardware unit 112 (MAC) and the device-dependent software unit 113. Connect to the dependency unit 110. The device-independent application unit 130 includes a hardware unit 111 (PHY), a hardware unit 112 (PHY), a hardware unit 112 (MAC), and a device that conceals the difference between the device-dependent software unit 113 and the hardware unit 111 (PHY) and hardware. Data is input / output between the hardware unit 112 (MAC) and the device-dependent software unit 113.

  The basic function unit 132 and the extended function unit 131 are connected via the device-independent API 22 (extension IF). The basic function unit 132 and the device dependent unit 110 are connected via the device independent API 27. The basic function unit 132 in the device-independent application unit 130 inputs information between the hardware unit 111 (PHY), the hardware unit 112 (MAC), and the extended function unit 131 instead of the middleware unit 120. Output.

  The device-independent application unit 130 inputs and outputs to / from each other via the basic function unit 132 as necessary. The extended function unit 131 of the device-independent application unit 130 inputs and outputs information via the basic function unit 132 and the device-independent API 22. The basic function unit 132 inputs and outputs information via the extended function unit 131 and the device-independent API 22, and the OAM unit, driver, firmware, hardware unit 111 (PHY), and hardware unit 112 (MAC) of the device-dependent unit 110. ) And the device independent API 27.

  Similar to the middleware unit 120 shown in FIG. 2, the basic function unit 132 inputs information as it is or in a predetermined format. For example, in the case of another device-independent application unit 130, the basic function unit 132 converts the input format into the device-independent API 22 format of the input format, and the device-dependent OAM unit, driver, firmware, and hardware unit. If there is, the information is input after being converted into the device-independent API 22 format of the input format or after being subjected to predetermined processing after termination. At the time of input, the basic function unit 132 deletes unnecessary input information at each input destination, and if there is insufficient information, it is collected and supplemented via the other device-independent API 22 or the device-independent API 27. It is desirable. However, the basic function unit 132 may broadcast or multicast the input to the input destination and broadcast it to related applications or the like.

  The device-independent application unit 130 includes, for example, extended function units 131-1 to 131-3 and a basic function unit 132. The device-independent application unit 130 may not include any one of the extended function unit 131 and the basic function unit 132. The device-independent application unit 130 may further include a function unit other than 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.

  It is preferable that the extended function unit 131 can be added or deleted independently without affecting other functions. For example, in accordance with service requirements, for example, when the extended function unit 131 is used for the multicast service and power saving support, the extended function unit 131 is added as needed, and deleted when it becomes unnecessary. However, it may be replaced or changed according to the change.

  The device-independent API 22 is preferably provided in advance in the basic function unit 132 assuming an extended function unit 131 to be added later. However, the device-independent API 22, the device-independent API 27, and other device-independent APIs are provided as necessary. You may add or delete in the form which suppresses the modification of the dependence application part 130. FIG.

(Fourth example of architecture)
FIG. 5 is a diagram illustrating a fourth example of the architecture of the communication device. The difference between the fourth example of the architecture and the third example of the architecture is that the communication apparatus includes a device-dependent application unit 150 under the basic function unit 132. As described above, the communication device of the fourth example of the architecture has the effect of simplifying the configuration of the basic function unit 132 by including the device-dependent application unit 150.

  The communication apparatus illustrated in FIG. 5 includes a device-dependent unit 110 and a device-independent application unit 130. The device-dependent unit 110 includes a hardware unit 111 (PHY) and a hardware unit 112 (MAC) that depend on a standard that conforms to or a device manufacturing vendor, and a hardware unit 111 (PHY) and a hardware unit 112 (MAC). A software unit 113 such as a driver and firmware for driving, and a device-dependent application unit 150 for driving at least a part of the device-dependent unit 110 are included. The device-independent application unit 130 is a porting IF and a hardware unit 111 (PHY), a hardware unit 112 (MAC), or a driver that hides the difference between the device-dependent software or the porting IF and the device-dependent application. It is a general-purpose device-independent application that executes device-independent processing via the unit 150. The basic function unit 132 in the device independent application unit 130 and the device dependent application unit 150 in the device dependent unit 110 are connected via the device independent API 27. The device dependent application unit 150 and other functional units of the device dependent unit 110 are connected via the device dependent API 24.

  The basic function unit 132 in the device-independent application unit 130 performs input / output with the hardware and the extended function unit 131 instead of the middleware unit 120. The basic function unit 132 may include a management / control agent unit 133 (see FIGS. 2 and 3) that receives communication from the EMS 140, and the management / control agent unit 133 is provided as the extended function unit 131. May be.

  The basic function unit 132 inputs the data as it is or in a predetermined format, similarly to the middleware unit 120 shown in FIG. As in the third example of the architecture, the basic function unit 132 may include a management / control agent unit 133 that receives communication from the EMS 140, and the management / control agent unit 133 is used as the extended function unit 131. You may prepare.

  The device-independent application unit 130 includes, for example, extended function units 131-1 to 131-3 and a basic function unit 132. The device-independent application unit 130 does not have to include any of the extended function unit 131 and the basic function unit 132 as in the third example of the architecture. The device-independent application unit 130 may further include functional units other than the extended functional unit 131 and the basic functional unit 132, as in the third example of the architecture.

  As in the third example of the architecture, it is preferable that the extended function unit 131 can be added, deleted, replaced, or changed without affecting other functions independently of each other. A part of the basic function unit 132 may be replaced with the device-dependent application unit 150. The device-dependent application unit 150 directly inputs / outputs information from the basic function unit 132. However, the device-dependent application unit 150 may input / output information to / from the EMS 140 without using the basic function unit 132, or after a predetermined conversion. Good.

  As in the first example of the architecture shown in FIG. 2, the device-independent APIs 22 and 27 are preferably provided in advance in the basic function unit 132 assuming an extended function unit 131 to be added later. The device-independent API 27, the other device-independent application unit 130, the device-dependent application unit 150, or the device-dependent API 24 may be added or deleted as necessary in a form that suppresses modification.

(5th example of architecture)
The upper right diagram in FIG. 6 is a diagram illustrating a fifth example of the architecture. The lower right diagram in FIG. 6 corresponds to first to fourth examples of architecture. This figure shows a case where the communication device is an OLT. The fifth example of the architecture is a functional cloud that uses existing / commercially available OLT hardware to prepare functions to be added / changed according to the service by implementing OLT functions on external hardware (cloudization) This is suitable for the approach of the conversion.

  In this example, the communication device includes existing / commercial hardware and external hardware. For example, the existing / commercial hardware is a non-generic device-dependent unit 110 that depends on the device, a middleware unit 121 that conceals the difference between hardware and software on the external hardware, and a general-purpose device whose operation does not depend on the device. The device-independent application unit 130 is provided. Therefore, the device-dependent part (vendor-dependent part) below the middleware in the figure is a functional part that depends on the standard that the equipment of the communication apparatus complies with and the manufacturer of the equipment. In addition, the device-independent application unit 130 is a functional unit that does not depend on a standard that the communication device device complies with or a device manufacturer.

  The middleware unit 121 and the device-independent application unit 130 are connected via a device-independent API that is an input / output IF independent of the device. For example, the software unit, the OAM, the hardware unit (PHY), the hardware unit (MAC), and the middleware unit 121 on the external hardware of the device-dependent unit 110 are device-dependent input / output IFs that depend on the device. Connected via API and inter-device connection between existing / commercial hardware and external hardware.

  This architecture facilitates flexible and quick addition of an extended function unit (unique function unit) by the device-independent application unit 130, and can provide a communication service in a timely manner. Here, the device dependence unit 110 may be the maintenance operation, access control, physical layer processing, and optical module shown in FIG. 6, and depends on the configuration of the device itself.

  For example, the device-dependent unit 110 or the device-independent application unit 130 is given priority by giving priority to a function with high update frequency such as DBA for improving the main signal priority processing or line utilization efficiency or a function contributing to communication service differentiation. You may decide. Furthermore, the device-independent application unit 130 may be used because the difference between the standards, generations, systems, systems, device types, and manufacturing vendors to which the devices to be shared are small is small.

  Even if it is not optimal for at least one of the compliant standards, generations, methods, systems, device types, or manufacturing vendors, any of the standards, generations, methods, systems, device types, or manufacturing vendor functions to comply with In order to generalize a common IF, a common IF 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, systems, systems, device types, and manufacturing vendors that the device-dependent unit 110 complies with.

  A conversion function unit that converts IF, parameters, and the like to correspond to the device-dependent unit 110 into at least one of the middleware unit 121, the driver of the device-dependent unit 110, and the device-dependent application unit 150 (vendor-dependent application unit). In addition, a function unit that automatically sets in response to an insufficient IF or parameter may be further provided.

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

  The device dependent unit 110 may not include PMD, MAC, PMA for serializing data, and PCS or PHY, which is a part for encoding data, connected to a physical medium. For example, only light-related functions may be provided without low-level signal processing such as modulation / demodulation signal processing, forward error correction (FEC), codec decoding processing, and encryption processing.

  The device-independent application unit 130 is, for example, a management / control agent unit 133 that acquires data from the EMS, extended function units 131-1 to 131-3, and a basic function unit 132. Hereinafter, items common to the extended function units 131-1 to 131-3 are referred to as “extended function unit 131” with a part of the reference numerals omitted. The EMS is, for example, a controller that controls network elements. 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 a configuration 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 may not include the extended function unit 131. In addition, 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 unnecessarily affecting other functions. For example, the extended function unit 131 may be appropriately added, deleted, replaced, or changed when the extended function unit 131 that executes multicast service and power saving correspondence is required in accordance with 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 lower-level function unit than the middleware unit 121. When the extended function unit 131 includes the basic function unit 132, the device-independent application unit 130 may not include the basic function unit 132. When a functional unit lower than the middleware unit 121 substitutes for the basic function unit 132, the device-independent application unit 130 may not include the basic function unit 132. When the extended function unit 131 includes the basic function unit 132 and a function unit lower than the middleware unit 120 replaces the basic function unit 132, the device-independent application unit 130 may not include the basic function unit 132.

  The management / control agent unit 133 does not need to input / output from / to the EMS 140 in the case where automatic setting is performed according to a predetermined setting without receiving communication from the EMS 140. Furthermore, when the management / control agent unit 133 does not have a management setting function and the other device-independent application unit 130, the basic function unit 132, and the device-dependent unit 110 have a management setting function, the device-independent application unit 130 The management / control agent unit 133 may not be provided.

  The EMS 140 and the device-independent application unit 130 may directly input / output information. The device dependence unit 110 may not include the NE management / control unit 115 and the NE management / control unit 115 IF.

  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-level function unit of the middleware unit 120. When the extended function unit 131 includes the basic function unit 132, when the lower-level function unit of the middleware unit 120 substitutes for the basic function unit 132, or in 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 that is a lower-level function unit of the middleware unit 120.

  The management / control agent unit 133 does not need to input / output information to / from the EMS 140 when performing automatic setting according to a predetermined setting. Further, when the management / control agent unit 133 does not include the management setting function and the other device-independent application unit 130, the basic function unit 132, and the device-dependent unit 110 have the management setting function, the device-independent application unit 130 The control agent unit 133 may not be provided. The EMS 140 and the device-independent application unit 130 may directly input / output information.

  Examples of input / output between the device-independent application unit 130 and the device-dependent unit 110 are as follows. For example, the DBA application unit and the protection application unit input / output information to / from the TC layer embedded OAM engine. The DWBA application and the ONU registration / authentication application unit input / output information to / from the TC layer PLOAM engine. The power saving application unit inputs and outputs information to and from the OMCI and L2 main signal processing function unit (L2 function unit). The MLD proxy application unit inputs and outputs information to and from the L2 function unit. The low speed monitoring application (OMCI) inputs / outputs information to / from the OMCI. The OMCI and L2 function units operate the XGEM framer and encryption. Here, DWBA and DBA may be separate, integrated, or combined. For example, the management / control agent unit 133 is an application unit for a maintenance operation function, and inputs / outputs information to / from the EMS 140 such as an NE controller for the NE management / control unit 115.

  The device-independent application unit 130 includes a device vendor, a method, a device type, a device generation, for example, ITU-TG. TWDM-PON 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 without depending on any of the BPON conforming to the 983 series. The device-independent application unit 130 is different from a device vendor, a method, a device type, a device generation, for example, 10GE-PON conforming to IEEE802.3av or IEEE1904.1 and GE-PON conforming to IEEE802.3ah. It is an application that works regardless of whether

  As an application of the extended function unit 131, only an application for driving functions provided for some vendors, methods, types, and generations, and devices of some vendors, methods, types, and generations via the device-independent API 21. The application which drives the function with which it prepares may be included.

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

  The middleware unit 120 inputs and outputs information via the device-independent application unit 130 and the device-independent API 21. The middleware unit 120 inputs and outputs information to and from the OAM unit 114, the driver, the firmware, the hardware unit 111 (PHY), or the hardware unit 112 (MAC) 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 unit of the device-independent application unit 130, the middleware unit 120 converts the information into the input format of each unit of the device-independent API 21. If the output destination is the OAM unit 114 of the device dependent unit 110, the driver, firmware, the hardware unit 111 (PHY), or the hardware unit 112 (MAC), the middleware unit 120 has the device dependent API 23 of the format to be input to each. The information is transmitted to the output destination after being converted into a format or after being terminated and subjected to predetermined processing.

  When inputting, the middleware unit 120 deletes unnecessary input information at each input destination, and if there is insufficient information, the middleware unit 120 can collect and supplement via the other device-independent API 21 or the device-dependent API 23. desirable. In addition, at the time of input to the middleware unit 120, it may be broadcast or multicast and broadcast to related applications or the like.

  The middleware unit 120 and the device-dependent unit 110 are exemplified as a single unit, but may be configured by 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 using inter-processor communication or the like across the processors and hardware. The device-independent application units 130 and the device-independent application units 130 may be arranged as an execution program such as a DLL on a user space on a single processor or on user spaces on a plurality of processors. May be.

  The device-independent application unit 130 may be arranged in the kernel space after securing an input / output IF such as an API, or may be arranged together with the middleware unit 120 having an IF 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 the kernel space may be arbitrarily combined 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, either may be selected by switching, both may be processed in cooperation, or actual processing may be performed by only one of them. The same applies to the software of the device dependent unit 110.

  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 in which the device-dependent application unit 150 is arranged also has a user space of the processor that performs the actual processing or a processor in the vicinity thereof from the viewpoint of the influence on other programs due to the restriction of the bus and the speed due to the communication between the processors and the occupation of the communication path. It is desirable to place it on kernel 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 advance in the middleware unit 120 assuming the extended function unit 131 to be added. However, the device-independent API 21 is necessary in a form that suppresses modification of the device-dependent API 23 and other device-independent application units 130. It may be added or deleted accordingly.

The device-dependent application unit 150 may include a management / control agent unit 133 corresponding to communication from the EMS 140.

27 to 29 show the main functions of the access system and specific examples of FASA application targets.
First, main functions of the access system will be described. The main functions of the access system include a PON main signal processing function, a PON access control function, an L2 main signal processing function, a maintenance operation function, a PON multicast function, a power saving control function, a frequency / time synchronization function, and a protection function.

  The PON main signal processing function is a group of functions for processing main signals transmitted to and received from the ONU. PHY adaptation, framing, service adaptation, PON frame generation / separation, forward error correction (FEC: Forward Error Correction) Etc. may be included. The PON main signal processing function is difficult to be softwareized.

  The PON access control function is a control function group for performing the above-described main signal transmission / reception, and includes ONU registration authentication control, ONU registration authentication application, DBA control, DBA application, DWA control (λ setting switching), DWA application (wavelength protection). And wavelength sleep.) May be included. The ONU registration authentication control application, DBA control application, and DWA application (including wavelength protection and wavelength sleep) of the PON access control function can be softwareized. Further, as an effect (differentiation factor) of extensibility of each function, the ONU registration authentication application has an authentication scheme concealment, the DBA application has a flexible QoS, and includes a DWA application (wavelength protection and wavelength sleep). ) Has a flexible QoS and is preferably softwareized.

  The L2 main signal processing function is a function group that transfers and processes a main signal between the PON side port and the SNI side port. MAC address learning, VLAN control, path control, bandwidth control, priority control, delay control, Functions such as Copy and traffic monitoring may be included. The L2 main signal processing function is difficult to be softwareized.

  The maintenance operation function is a group of functions for smoothly maintaining and operating a service by an access device, and functions for setting ONU and OLT (OSU and switch) devices, software update, device and service management, and various functions are normal. A function to monitor whether it is operating normally, a function to issue an alarm when an abnormality occurs, a test function to investigate the range and cause of the abnormality, device setting / management, setting / management application, low-speed monitoring / test, low-speed monitoring An application (ONU / OLT monitoring: EMS), a low-speed monitoring application (OMCI), a high-speed monitoring / control, a high-speed monitoring application, and the like may be included.

  In addition, the maintenance operation function is connected to a maintenance operation system that manages a large number of access devices, thereby realizing smooth maintenance operation from a remote location. As for the maintenance operation function, the setting / management application, the low speed monitoring (OMCI) application, and the high speed monitoring application can be softwareized, and the low speed monitoring application (ONU / OLT monitoring) depends on the situation. Also, as an effect (differentiation factor) of the extensibility of each function, the setting / management application has the effect of drastically reducing Opex by cooperating with the controller, and the low-speed monitoring application (ONU / OLT monitoring: EMS) It has the effect of drastically reducing Opex by cooperating with EMS.

  The PON multicast function is a function group that forwards a multicast stream received from the SNI side to an appropriate user. A function for identifying and allocating a multicast stream, setting an ONU filter, MLD proxy, multicast (frame processing), etc. May be included. The MLD proxy application can be softwareized.

  The power saving control function (access control) is a group of functions for reducing the power consumption of ONUs and OLTs. In addition to the power saving function specified in the standardization, the influence on the service is achieved by linking with the traffic monitor. It may include a function for obtaining the maximum effect while minimizing, a power saving control, and a power saving application. Power-saving apps can be softwareized. Further, as an effect (differentiation factor) of extensibility of each function, the power saving application has a flexible QoS effect.

  The frequency / time synchronization function is a group of functions for providing accurate frequency synchronization and time synchronization to devices under the ONU. A function for subordinately synchronizing its own real-time clock to the host device, and a time to the ONU using a PON frame. A function for notifying information and a frequency / time synchronization function may be included. The frequency / time synchronization function is difficult to be softwareized.

  The protection function is a function group for continuing the service by switching or taking over from the active system to the standby system when a failure is detected in a configuration where redundancy is provided by a plurality of hardware such as between switches and OSUs. , Functions such as switching trigger detection and switching processing, protection functions include functions to keep the service running in degenerate operation without stopping the service completely when detecting a failure or switching manually, protection control, protection algorithm (application) May be. The protection algorithm (application) can be softwareized. Further, the protection algorithm has the effect (differentiation factor) of the extensibility of each function.

Next, the concept and an example of whether each function is implemented as a FASA application or on a FASA platform will be described. Whether each function is implemented as a FASA application or on a FASA infrastructure is shown in the FASA application / FASA infrastructure items of FIGS.
Among the functions, functions that need to be changed depending on services and functions that should be extended to satisfy the requirements unique to the telecommunications carrier are realized as FASA applications. On the other hand, functions defined by standardization and the like that have little room for expansion are mounted on the FASA base. For example, FIG. 27 shows that the PON main signal processing function is realized as a FASA base. Basic PON main signal processing functions such as frame format, frame encryption, and forward error correction (FEC) function are required to realize 40 Gbit / s-class access devices compliant with ITU-T G.989 series. Must be implemented according to standards. Since these basic functions are common regardless of services, they are implemented on the FASA infrastructure.

  As another example, FIG. 27 shows that the DBA function included in the PON access control function “responding to a service request (eg, low-latency request for mobile provision)” is realized as a FASA application. For example, there are cases where low latency is provided depending on the provided services and cases where bands are efficiently allocated to a large number of users. In order to satisfy different requirements for each service, it is desirable to separate the bandwidth allocation procedure and policy as a FASA application from standard processing (conversion to the BWmap format, etc. defined in the standard).

  Even if the target of the service to be provided is for the same mass, it is conceivable that the fairness policy is different, for example, the response policy for heavy users differs depending on the communication carrier. Specifically, for example, a telecommunications carrier that requires fair control with a small granularity, such as a PON unit, performs fair control even within the DBA application, and a telecommunications carrier that performs fair control only with a large granularity, such as an access device unit, has a concentrating function. It is assumed that each QoS specification is satisfied by using.

  Thus, in FASA, since different requests are realized by replacement of the FASA application, a means for replacing the FASA application is required, but what is adopted as the replacement means varies depending on the telecommunications carrier and the operation. For example, when an existing maintenance operation system used by a telecommunications carrier uses TFTP (Trivial File Transfer Protocol) for software update, it is equipped with TFTP and is updated from outside the maintenance operation system using SFTP (SSH FTP). In some cases, SFTP is provided.

  In the future, it is assumed that discussions on standardization regarding the interface between the device and the controller will progress, and it is necessary to consider additions and changes to the interface following the progress of standardization. For this reason, other systems to which the access device is connected and functions that require customization in accordance with the operation thereof may be realized as FASA applications.

  In addition, in FASA, not only protection performed by fully duplicating the entire FASA infrastructure but also protection performed only by a part of the FASA infrastructure is assumed. For example, when the FASA base is equipped with an optical switch and supports PON protection, when a single PON is equipped with multiple wavelengths and supports wavelength protection, when only the switch is duplicated, or when these are combined A plurality of redundant configurations are conceivable. By implementing the protection function as a FASA application, it is possible to cope with the expected redundant configuration, and it is possible to easily cope with various redundant configurations by reusing the corresponding part.

  Further, a function to be converted into a FASA application, that is, an extended function, may be an extended function according to the importance of realizing the update frequency of the function, unique specifications, etc., among the functions that can be converted to software. It is preferable to use the middleware for FASA application API other than the basic function and the device-independent application, device-dependent software, and hardware that have a low update frequency or a low requirement for realizing the original specification or the like. In particular, it is preferable to leave the functions that are limited by the processing capability of the software as hardware. For example, a function that contributes to service differentiation or a high frequency of renewal such as DBA to improve main signal priority processing and line usage efficiency, or management that is closely related to the operator's work flow and requires unique specifications for each operator From control functions to extended functions.

  Here, the evaluation of whether or not the software can be made is an example on the assumption that the processing capability of the OLT assumed around 2018 and the application of the soft switch is not assumed. It may be changed as appropriate assuming an assumed processing capacity and application of a soft switch. Further, the internal configuration of each function may be another configuration as long as the same function can be realized.

  As shown in the figure, the algorithm is the main software area. A function defined as a software area is a device-independent application on a device-independent API. For example, algorithms in the ONU registration authentication function, DWBA (DBA + DWA) 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, a function that contributes to service differentiation or a high frequency of renewal such as DBA to improve main signal priority processing and line usage efficiency, or management that is closely related to the operator's work flow and requires unique specifications for each operator From control functions to extended functions. An example of the architecture based on FIGS. 27 to 29 is shown in FIG.

  FIG. 8 is a diagram illustrating an example of the configuration of an optical access system. The OLT shown in the figure is an example of the communication device 100. In the optical access system according to FIG. Complies with 989 series. In FIG. 8, the controller and the external device are not included in the OLT, but are described in order to illustrate communication with the FASA application API.

  The logical model includes a FASA application and a FASA base that provides the FASA application with a FASA application API. The FASA infrastructure includes middleware for the FASA application API. The FASA application API middleware absorbs differences in hardware and software vendors and methods that make up the FASA infrastructure. A FASA application API set independent of vendors and systems is defined on the middleware for the FASA application API, and necessary functions are realized for each service or each communication carrier by replacing the FASA application. Communication between FASA applications and setting management by a controller or the like are performed via the FASA application API middleware. Note that FASA application API middleware may not be used. The FASA application API set is a common API group used in the FASA application, and an API required for each FASA application is selected from the API set and used.

As an example of function sharing, processing by an application can be performed except for hardware Config, and processing by an application on the external server 16 in FIG. 7 can be performed without having software and setting data in an ONU or OLT. It can also be realized by unifying commands and defining sequences.

  FIG. 14 is a diagram illustrating a second example of the function configuration of the maintenance operation function unit 330. The processing that constitutes the functions of the maintenance operation function unit 330 includes apparatus state monitoring (CPU / memory / power supply / switching), traffic monitoring, alarm monitoring (ONU abnormality, OLT abnormality), and test (loopback).

Further, in the main function of the PON multicast function unit 350, it is required that the zapping performance (Zapping performance) (JOIN latency) conforms to a rule such as an average of 1.5 seconds or less as packet processing.

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

  FIG. 17 is a diagram illustrating an example of a functional configuration included in the power saving control function unit 360. The processing that constitutes the functions of the power saving control function unit 360 includes sleep proxy / traffic monitoring, ONU wavelength setting, and transition between wavelength settings.

The power saving control state transition management (driver unit) requires speed, but can also be processed by an application. For the traffic monitor, only the configuration can be processed by the application.

  FIG. 18 is a diagram illustrating an example of a functional configuration of the frequency / time synchronization function unit 370. The OLT subordinately synchronizes its own real-time clock (RTC) to the host device by SyncE (Synchronous Ethernet (registered trademark)) (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.

It is required to comply with regulations such as 987.3). As an example of function sharing, the real-time clock itself is the device-dependent unit 110, and the time adjustment calculation to the higher-level device can be processed by an application (the device-dependent unit 110 can also be used depending on accuracy).

  FIG. 19 is a diagram illustrating an example of a functional configuration of the protection function unit 380. As a process constituting the protection function of the protection function unit 380, redundant switching (CT, SW, NNI, CONT, PON (Type A, B, C)) is provided. These processes may be configured by 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 milliseconds or less. As an example of function sharing, processing by an application can be performed except for hardware switching trigger detection and switching processing such as failure detection. When a redundant path is not set in advance and an instruction is given to (from) the EMS when a switching trigger is detected, it is device-dependent.

  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 assumed to be a device-independent application unit 130 on the device-independent APIs 21 and 22. For example, algorithms in the ONU registration or authentication function, DWBA function, setting / management / monitoring control function, and power saving control function that contribute to the differentiation service are handled as the extended function unit 131 in the device-independent application unit 130. The MLD proxy application includes a multicast function.

  The extended function unit 131 is set as the extended function unit 131 in accordance with the importance of the update frequency of the function, the implementation of the original specification, etc. in the application. Those having a low update frequency or a low requirement for realization such as original specifications are middleware units 120 other than the basic function unit 132 and device-independent application unit 130, device-dependent software, hardware unit 111 (PHY), and hardware unit 112 ( MAC). In particular, it is preferable to leave the hardware unit 111 (PHY) and the hardware unit 112 (MAC) as functions that have limitations due to software processing capabilities. For example, a function that contributes to service differentiation or a high frequency of renewal such as DBA to improve main signal priority processing and line usage efficiency, or management that is closely related to the operator's work flow and requires unique specifications for each operator The extended function unit 131 is designated as the control function.

The NE control 115b is connected to a low-speed monitoring application (EMS-IF).

  FIG. 21 is a diagram illustrating a flow of signals / information between functional units in the communication apparatus. This figure shows the flow of signals / information between functional units in the communication apparatus, focusing on OLT In / Out. As shown in the figure, the OLT as a communication apparatus is composed of an API lower processing entity (FASA platform) and an application (FASA application).

The lower API processing entity includes an MPCP / DBA processing entity in which the OLT input / output target is a transmission instruction and reception notification for MPCP transmission / reception, an OAM processing entity in which the OLT input / output target is OAM transmission / reception, and an OLT input / output target in ONU authentication transmission / reception. One ONU authentication processing entity, MLD / IGMP processing entity whose OLT input / output target is MLD / IGMP transmission / reception, Other protocol processing entity whose OLT input / output target is other protocol transmission / reception, OLT input / output is main signal processing such as bridge / encryption The main signal setting processing entity for setting, reference / status acquisition, and the device management processing entity for which the OLT input / output target is OLT hardware / IF / OS are illustrated. Here, it is desirable that the transmission instruction and the reception notification for MPCP transmission / reception should be something like send_frame (* raw_frame);
In the figure, DBA, ONU management, line management, multicast, EtherOAM, redundancy, device management, alarm management, Netconf agent, and application management are illustrated as applications.

  OLT In / Out is roughly divided into three types: input / output to the ONU, setting / notification to the OLT itself, and input / output to / from the EMS. When viewed from the application above the API, it is (a) simpler (convenient) and (b) common (between multiple types) compared to the process of hitting the driver for the lower API processing unit. (C) It is desirable that there is a processing entity for convenient processing.

  The function sharing of the API lower processing entity will be exemplified below. The app has a corresponding process. The function sharing between the API lower processing entity and the application may be any of the following, or may be different, and may be different for each processing actual state.

(0) Message Through: The message is passed through the upper part of the API and the ONU / upper NW.

(1) Framing: The message is provided to the upper part of the API by removing the frame and disassembling or processing the message as necessary. Information is passed from the upper part of the API to the lower part of the API. The API lower processing entity performs framing. Since the API is highly dependent on each protocol, it may be included in the device-dependent application unit. Fixed parameters (such as type values) are preferably set and retained from the top of the API at the time of initialization. The setting parameter is returned in response to the reference from the upper part of the API.

(2) Automatic response: The processing entity is responsible for message transmission and reception that does not require judgment, such as periodic transmission and fixed response. It is desirable to set the operation in advance from the top of the API. For example, response period. The result is notified only when notification to the upper part of the API is necessary.

(3) Autonomous judgment: A process entity also handles a process involving judgment. A policy is set in advance from the top of the API.

  This figure is described in conformity with IEEE-compliant 10GEPON, but the same applies to ITU-T and other compliant devices as long as the corresponding functions and processes are read. The functions and actual processing are examples, and may be appropriately added, deleted, replaced, and changed according to conditions.

  FIG. 22 is a diagram illustrating an example of an application executed by the communication device. CPU processing is classified into three groups. The three groups are a CPU for Cont, a CPU for OSU, and a CPU for SW. The CPU processing for the Cont is a process for executing a low-speed monitoring application (OMCI), a low-speed monitoring application (EMS-IF), and a setting / management application. The process of the CPU for SW is a process of executing the MLD proxy application. The CPU processing for the OSU is a process for executing a power saving application, a protection application, a high-speed monitoring application, a DBA application, a DWBA application, and an ONU registration authentication application. The device setting IF may be a part of the EMS-IF or may be equivalent to the device-dependent API 25.

  This is an example in which each application is processed by a CPU on a CPU package. In FIG. 22, each application is directed to a control package (Cont.

The OSU group is a power saving application, a protection application, a high-speed monitoring application, a DBA application, a DWBA application, an ONU registration authentication application, a SW group is an MLD proxy application, a Cont group is a low-speed monitoring application (OMCI), and a low-speed monitoring application (EMS- IF), a setting management application. Further, although centralized control by the CPU is assumed, the classified applications of each group may be distributed and arranged in each package (Cont, OSU, SW). Moreover, you may arrange | position on either of Cont, OSU, SW, or those some combination irrespective of said classification | category. 22 may be a part of the EMS-IF or may be equivalent to the device-dependent API 25 of 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 other embodiments.

  FIG. 23 shows an example in which an application is arranged on a server or the like instead of the CPU package. The application is processed on a server or the like, and the processing result of the application arrives at the OLT after being transmitted on the transmission line in a format that can be transmitted on the transmission line such as an Ethernet (registered trademark) frame. Here, as a format that can be transmitted through the transmission path, a frame other than the Ethernet (registered trademark) frame, transmission of TDM, or the like may be used. The processing result is transmitted via a converter (Conv. In FIG. 23). However, if the OSU, SW, or λ card can receive the processing result of the application without passing through the converter, the conversion is performed. No machine is required. The server or the like may be equivalent to the external server 16 in FIG. 7 or may be equivalent to the proxy unit 15.

The CPU shown in FIG. 25 may be the CPU package shown in FIG. 23, the server shown in FIG. The OSU MAC assumes a dedicated LSI that performs OSU processing, but a general-purpose LSI may be used as long as equivalent processing is possible.

  In the example of FIGS. 2 and 3, the software area is the basic function unit 132, the management / control agent unit 133, the extended function unit 131, and the middleware unit 120. However, the software area is a service adaptation (encryption). Fragment processing, GEM framing / XGEM framing, PHY adaptation FEC, scramble, synchronous block generation / extraction, GTC (GPON Transmission Convergences) framing, PHY framing, SP conversion, and coding method may also be targeted. An example of implementation of a software function of the architecture and an example of function deployment corresponding to the hardware unit 111 (PHY) and the hardware unit 112 (MAC) will be described. With functionality .

  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, the middleware unit 120 is mounted on each OSU and switch, and a software 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 OSU extended function unit 131, a switch extended function unit 131, and a control unit extended function unit 131. The OSU extended function unit 131 is, for example, a power saving application, a protection application, a DBA application, or an ONU registration authentication application. The extended function unit 131 for switches 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), or a setting / management application. The EMS is, for example, an OSS (Operation Support System).

  G. In the case of 989.3, for example, as shown in FIGS. In the case of a DBA application, the middleware unit 120 shown in FIGS. 2 and 3 or the basic function unit 132 shown in FIGS. 4 and 5 is an embedded TC layer hardware unit 111 (PHY) and hardware unit 112 (MAC). The OAM engine (Embedded OAM Engine) is operated. And the transmission / reception part which is the hardware part 111 (PHY) of the PMD layer and the hardware part 112 (MAC) receives according to the DBA application. When the transmission / reception unit receives an upstream signal that does not comply with the DBA, the transmission / reception unit may not comply with the DBA application.

  The information processing unit is not limited to these software functions, and may have other software functions. The hardware unit 111 (PHY) and the hardware unit 112 (MAC) are not limited to a transmission / reception unit, an OSU, a switch, a control unit, and an 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. As shown in FIG. 7, a proxy unit or an external server that processes signals input to and output from the switch may be provided on the NNI (Network-Network Interface) side of the switch. The external server 16 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 capability or processing delay. The OSU may include the switch unit 12 or the switch unit 13, or may include a switch (the switch unit 12 in the case of including the switch unit 13) 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, 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 in accordance with the status of deployment of the extended function unit 131, the computing capability of the location where computation is possible, the computation load, power consumption, and the like.

  The main functions related to the main signal processing of the OLT and the relationship between the functions will be described. 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 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 before the shaper, Max or Demux (Mux / DMux) and queue, and a shaper before framing.

  A multicast function such as a copy function at the front stage of the shaper and an MLD proxy used for copying is provided in the switch. In this way, the PON basic function unit is reduced by providing the PON main signal processing function and the PON access control function 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, as an example of the function of the switch, Classifier (Classifier), Modifier (Modifier), Policer / Shaper (Policer / Shaper), Cross Connect (Cross Connect), Queue (Queue), Scheduler (Scheduler) However, you may change suitably. 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 The terminal may be used only for termination, and all functions of Classifier, Modifier, Policer / Shaper, Cross Connect, Queue, and Scheduler may be implemented by the switch, or only Modifier, Cross Connect, Queue, and Scheduler may be implemented by the switch.

  Furthermore, if a VID or the like describing 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, Scheduler can be placed in the qua Modifier, Queue, Policer / Shaper, Cross Connect, and Scheduler may be used, or Classifier, Queue, Polymer / 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, Policer / Shaper It is desirable to execute processing by Policing / Shaping after leveling with Queue in the previous stage.

  In the state transition to a specific state, the subject such as the sleep operation stores the instruction of the subject such as the sleep operation (equipment included in the communication device) outside the subject independent of the subject such as the sleep operation, It is possible to inherit the behavior. The specific state is, for example, a sleep state, a switching state of an active communication device, a user accommodation switching state, or a multicast state. Since the information is held outside the communication device, it is possible to prevent loss of inheritance such as a sleep operation when switching to another communication device. The communication device can ensure inheritance of information held by the device.

  In addition, by diverting a general-purpose and softwareized switch as an execution unit, it is possible to realize an OLT that can add functions inexpensively, flexibly and quickly to a general-purpose and softwareized switch.

  The configuration according to Embodiment 1-1 shown above is the same in the following embodiments, and may be combined as appropriate. For example, FIG. 2 illustrates a case where the configuration of the execution unit is only the transmission / reception unit 11 (TRx), the switch unit 12 and the switch unit 13 in FIG. 2, but the transmission / reception unit 11 (TRx), the switch unit 12 and the switch unit are illustrated. A place other than 13, a place other than that, a place where the PON ends, and the control unit 14 may be the execution unit.

(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. In the WDM-PON, except that the function of time-division multiplexing the bandwidth resources of the PON section of the ONU-OLT between the ONUs such as the DBA is not required, the embodiment 1-3 is the embodiment 1-1. It is the same.

(Embodiment 1-4)
This embodiment is a combination including OFDM (Orthogonal Frequency Division Multiplex) -PON, CDM (Code Division Multiplex) -PON, SCM (Subcarrier Multiplex) -PON, and core division multiplexing.

  In the embodiment 1-1, the configuration used for the TWDM-PON is exemplified, but it may be applied to a PON sharing resources other than the wavelength and time. 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. Multiplexing may be used together, spatial division multiplexing using a multi-core fiber or the like may be used together, or wavelength division multiplexing may not be used. 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 second 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 so that the GEM frame is conducted between the switch and other portions. By transferring to the switch until the GEM encapsulation, the L2 function unit can be excluded from the protocol stack of the other part, and the L2 function unit can be prevented from being overlapped by the switch and the other part.

  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 third 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 inputting and outputting control information via a switch, there is an effect that processing other than the switch is lightened. In addition to the transfer of the third 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.
