Description

The present invention relates to a subscriber line end station device and a setting reflection method.

In the field of networks, virtualization technologies such as SDN (Software Defined Network) and NFV (Network Function Virtualization) are being introduced.
The SDN separates the transfer function and the control function in the network into a data plane and a control plane, respectively. Then, the SDN converts the control function into software and arranges it in a cloud or the like on the control plane to control the communication device on the data plane. As a result, according to SDN, flexible configuration changes are possible, which is expected to improve the efficiency of network operation.
In addition, NFV softwareizes network functions including main signal processing in communication devices, and applies the network functions to general-purpose devices (for example, on PC (Personal Computer) servers, white box switches, etc.) or in the cloud. It is a technology to operate on. According to NFV, this will increase the degree of freedom in adding, deleting, and renewing network functions, and it is expected that CAPEX (Capital Expenditure) will be reduced by using general-purpose equipment and the cloud.
Then, based on the above-mentioned concepts of SDN and NFV, studies have been made on the application of virtualization technology to access devices (for example, Non-Patent Document 1 and Non-Patent Document 2).

First, a conventional access device will be described.
In general, a conventional access device is a dedicated device for each system or vendor using dedicated hardware (for example, a dedicated chip), so that the system of input commands (for example, Config command) in the setting of the access device is used. It depends on the system and vendor. Specifically, since the access device is a dedicated device, the MIB (Management Information Base) of CLI (Command Line Interface) and SNMP (Simple Network Manager Protocol) is different. Therefore, it is necessary to prepare a management system (for example, EMS (Element Management System)) for setting, monitoring, and controlling the access device for each access device of a different system or vendor. ..

FIG. 1 is a schematic view showing an example of the configuration of a conventional access device and a management system. As shown in the figure, there are an access device 50a-1 of vendor A, an access device 50a-2 of vendor B, and an access device 50a-3 of vendor C, and these three access devices are dedicated devices for each vendor. be. Therefore, the access device 50a-1, the access device 50a-2, and the access device 50a-3 store different MIBs (MIB (A company), MIB (B company), and MIB (C company)), respectively. .. Therefore, the access device 50a-1, the access device 50a-2, and the access device 50a-3 are managed by different management systems (management system 60a-1, management system 60a-2, and management system 60a-3). ..

Even if the communication carrier is the same system (for example, GE-PON (Gigabit Ethernet-Passive Optical Network)), the access device EoS (End of Sales) and EoL (End of) are considered based on the sustainability and stability of the service. Access devices from multiple vendors may be installed in preparation for risks such as Life) and malfunctions. As described above, when the communication carrier provides the service using the access devices of the plurality of vendors, the maintenance and operation methods are different for each access device, and the work becomes complicated.

In contrast to the above conventional technology, there is a management system that uses XML (Extensible Markup Language). XML is data that models a procedure and a processing target.

FIG. 2 is a schematic diagram showing the configuration of an access device and a management system that perform processing with conventional modeled data. As shown in the figure, there are an access device 50b-1 of vendor A, an access device 50b-2 of vendor B, and an access device 50b-3 of vendor C, and these three access devices are dedicated devices for each vendor. be. Then, the access device 50b-1, the access device 50b-2, and the access device 50b-3 all perform processing using XML which is modeled data.

However, since the XML structure differs depending on the OS (Operating System; basic software) installed in the access device, it is necessary for the management system side to deal with each access device having a different system or vendor as in the above-mentioned conventional technology. .. Therefore, as shown in FIG. 2, the access device 50b-1, the access device 50b-2, and the access device 50b-3 have different management systems (management system 60b-1, management system 60b-2, and management system, respectively). It is managed by 60b-3).

<First Embodiment>
Hereinafter, the first embodiment of the present invention will be described.
[Overall configuration of general-purpose equipment and management system]
Hereinafter, the overall configuration of the general-purpose device and the management system will be described with reference to the drawings.

FIG. 3 is a schematic view showing an example of the overall configuration of the general-purpose device 10a and the management system 20a according to the first embodiment of the present invention. As shown in the figure, two general-purpose devices (general-purpose device 10a-1 and general-purpose device 10a-2) and a management system 20a are connected. Hereinafter, when it is not necessary to distinguish between the general-purpose device 10a-1 and the general-purpose device 10a-2, the general-purpose device 10a-1 is simply referred to as the general-purpose device 10a. In FIG. 3, the number of general-purpose devices 10a is assumed to be two, but the number is not limited to this, and the number of general-purpose devices 10a is arbitrary.

The general-purpose device 10a includes, for example, a PC server. The general-purpose device 10a constitutes a virtual OLT (Optical Line Terminal; subscriber line terminal device) in which the functions of the access device are implemented as software on an OS such as Linux (registered trademark).

The OLT is a device that realizes communication with another communication device (for example, ONU (Optical Network Unit; subscriber line terminal unit)) by an optical signal passing through an optical communication network. The optical communication network to which the OLT is connected is, for example, a passive optical communication network such as PON (Passive Optical Network). The OLT is installed, for example, in a station building connected to an optical communication network. The ONU is a device that realizes communication with other communication devices by an optical signal passing through a communication network. The communication network to which the ONU is connected is, for example, an optical fiber network such as PON. The ONU is installed in the home of a user who receives a communication service, for example.

As shown in FIG. 3, the general-purpose device 10a constitutes a virtual machine XX-PON and a virtual machine YY-PON. Here, XX and YY represent the types of PON (for example, GE-PON, G-PON, etc.), and XX-PON and YY-PON are different types of PON.

The management system 20a operates a management application that manages the general-purpose device 10a on the OS and middleware. The management application of the management system 20a communicates with the general-purpose device 10a by, for example, a communication protocol such as NETCONF, and sets, controls, and monitors the virtual machine of the general-purpose device 10a. The management application gives an instruction to the virtual machine by transmitting instruction data generated in a data format such as XML.

The Cont unit (control unit) of each virtual machine of the general-purpose device 10a acquires the above-mentioned instruction data, and operates the main signal processing unit based on the instruction data.

As shown in FIG. 3, in the present embodiment, the function of the access device is made into a software component and configured as a virtual machine on the general-purpose device 10a. Therefore, if the same system (for example, XX-PON) is used, the same function is used. There is no need to prepare multiple software parts. For example, the XX-PON of the general-purpose device 10a-1 and the XX-PON of the general-purpose device 10a-2 can be managed by the same management application. When a newly managed system (for example, YY-PON) is added, it is necessary to add a function to the management application, but YY-PON of the general-purpose device 10a-1 and YY- of the general-purpose device 10a-2. Since it can be managed by the same management application as PON, it is not necessary to add a function to the management application for each general-purpose device 10a.

As described above, in the present embodiment, the function of the access device is made into a software component and configured as a virtual machine on the general-purpose device 10a, so that each vendor in the Config setting for the virtual machine configured on the general-purpose device 10a and the like. There is no difference. Therefore, in the present embodiment, it is not necessary to prepare the management system 20a for each general-purpose device 10a. Thereby, according to the present embodiment, a plurality of general-purpose devices 10a can be managed by one management system 20a.

[Functional configuration of general-purpose equipment and management system]
Hereinafter, the functional configurations of the general-purpose device 10a and the management system 20a will be described with reference to the drawings.
FIG. 4 is a diagram showing a functional configuration of the general-purpose device 10a and the management system 20a according to the first embodiment of the present invention. As shown in the figure, the management system 20a is connected to the general-purpose device 10a. For the sake of brevity, the number of general-purpose devices 10a is assumed to be one. For example, as shown in FIG. 3, a plurality of general-purpose devices 10a are connected to one management system 20a. It doesn't matter if you do.

As shown in the figure, the general-purpose device 10a includes an OS 100a, a common base unit 101a, and two functional units (functional unit A102a-1 and functional unit B102a-2). Hereinafter, when it is not necessary to distinguish between the functional unit A102a-1 and the functional unit B102a-2, the functional unit 102a is simply referred to as the functional unit 102a.

The general-purpose device 10a is a device that constitutes a virtual OLT (hereinafter, referred to as “virtualized OLT”) operated by the functional unit 102a implemented as software on the OS 100a.
The common base unit 101a reflects the setting request in the setting of the functional unit 102a based on the setting request from the management system 20a regarding the setting of the functional unit 102a. Further, the common base unit 101a includes a storage unit 1011 that stores a setting information table described later.

For instructions from the management system 20a to the general-purpose device 10a, a common base unit 101a is provided in the general-purpose device 10a to standardize the instruction format (instruction format), so that different functional units (for example, functional unit A102a-1) can be instructed. And the functional unit B102a-2) can also be performed by a common instruction format.

For example, as an example of the instruction format, as in the instruction format f1 shown in FIG. 4, the type of instruction such as whether to set for each function unit 102a or to acquire information from each function unit 102a can be determined. It is assumed that the instruction format is a combination of the command classification shown and the command (group) that encapsulates each command itself to each function unit 102a, and the instruction data based on the instruction format is transmitted from the management system 20a. It is transmitted to the common base unit 101a. By prescribing the command system (command size, order, etc.) for each functional unit 102a, the encapsulated commands for each functional unit 102a can be correctly decapsulated in the common base unit 101a. ..

Further, the general-purpose device 10a previously stores the information (setting information table) in which the command classification, the command, and the functional unit 102a corresponding to the command are associated with each other and listed are stored in the storage unit 1011 in the common base unit 101a. keeping. The setting information table may be stored in a storage device outside the common base unit 101a.
Thereby, the common base unit 101a can specify which function unit 102a the deencapsulated command corresponds to by referring to the above setting information table. Then, the common base unit 101a identifies, respectively, which function unit 102a the deencapsulated plurality of commands are for, and then distributes and notifies the corresponding function unit 102a of the specified plurality of commands. , The setting is reflected for each functional unit 102a.

In the virtualized OLT in which the function of the access device is implemented as software on the general-purpose device, it is necessary to set the function from the management system side in the prior art. For example, if the functional unit A of the general-purpose device 10a is created by the vendor A and the functional unit B is created by the vendor B, if each vendor freely creates the command, the command for setting the function is set. The system of commands (setting commands) will be different. Therefore, the specifications on the management system side that instruct the setting also differ for each functional unit. On the other hand, the general-purpose device 10a according to the present embodiment is characterized in that the functional parts of the general-purpose device 10a are standardized so as not to be vendor-dependent.

As described above, according to the present embodiment, even if a plurality of functional units 102a are created by different vendors, the instruction format transmitted from the management system 20a to the general-purpose device 10a is unified, and the command and the functional unit are unified. By having the storage unit 1011 of the common base unit 101a of the general-purpose device 10a hold the setting information table associated with the 102a in advance, the influence on the management system 20a side due to the difference between the vendors, that is, the management system No modification to 20a is required.

Hereinafter, a more specific description will be given. As shown in FIG. 4, the instruction format f1 of the instruction transmitted from the management system 20a to the common base unit 101a is headed with information indicating the command classification. In the command classification, for example, "Set" is arranged for the instruction of "setting" to the functional unit 102a, and "Get" is arranged for the instruction of "acquisition" of the information from the functional unit 102a. Then, after the information indicating the command classification, a command (group) in which a plurality of commands are encapsulated is placed. For example, a command (group) in which data in which a command for the functional unit A102a-1 and a command for the functional unit B102a-2 are arranged in order is encapsulated is arranged after the information indicating the command classification.

Upon receiving the instruction from the management system 20a, the common infrastructure unit 101a decapsulates the encapsulated command, and identifies which function unit 102a each command after decapsulation is for. The identification is performed based on the setting information table t1 illustrated in FIG. As shown in the figure, the setting information table t1 is a two-dimensional tabular data composed of a column of three items of "command classification", "command", and "corresponding functional unit".

For example, if the command classification of the instruction that received the instruction from the management system 20a is "Set" and one of the decapsulated commands is "XXX", the common infrastructure unit 101a has the setting information table t1. The value (that is, "functional unit A") of the "corresponding functional unit" corresponding to the command classification ("Set") and the command ("XXX") is acquired with reference to. Thereby, the common base unit 101a can specify that the command is a command for the functional unit A102a-1. Similarly, for example, if the command classification of the instruction that received the instruction from the management system 20a is "Set" and one of the decapsulated commands is "YYY", the common infrastructure unit 101a will use the command. Can be specified as a command for the functional unit B102a-2.

The common base unit 101a distributes and outputs the command classification and the command to the functional unit 102a specified above. At this time, for example, as in "Set_XXX", the command classification and the command are output to each function unit 102a as data linked by an underscore.

As described above, in the present embodiment, the instruction given from the management system 20a to each functional unit 102a is given via the common base unit 101a. Then, in the present embodiment, in order to prevent the management system 20a from being required to be modified each time the functional unit 102a is added, the command to each functional unit 102a is concealed (encapsulated). , Is transmitted from the management system 20a to the common base unit 101a.

By prescribing rules (instruction format) between the common infrastructure unit 101a and the management system 20a, the management system 20a does not need to interpret the data structure or recognize the command. , There is no influence on the management system 20a side due to the difference of the vendor who developed the functional unit 102a. Therefore, it is not necessary to modify the management system 20a.

[Operation of general-purpose device]
Hereinafter, the operation of the general-purpose device 10a will be described with reference to the drawings.
FIG. 5 is a flowchart showing the operation of the general-purpose device 10a according to the first embodiment of the present invention. This flowchart starts when instruction data based on a predetermined instruction format is transmitted from the management system 20a to the general-purpose device 10a.

(Step S001) The common base unit 101a of the general-purpose device 10a acquires instruction data transmitted from the management system 20a. After that, the process proceeds to step S002.
(Step S002) The common base unit 101a of the general-purpose device 10a recognizes the command classification included in the instruction data acquired in step S001. After that, the process proceeds to step S003.

(Step S003) The commands (groups) included in the instruction data acquired by the common base unit 101a of the general-purpose device 10a in step S001 are encapsulated. The common base unit 101a decapsulates the encapsulated command (group). Then, the common base unit 101a recognizes one or a plurality of deencapsulated commands. After that, the process proceeds to step S004.
(Step S004) The common base unit 101a of the general-purpose device 10a refers to the command classification, the command classification, and the setting information table t1 in which the command and the corresponding functional unit are associated with each other, and the command classification recognized in step S002 and step S003. Each command recognized in the above and the functional unit 102a corresponding to the above are specified. Then, the process proceeds to step S005.

(Step S005) The common base unit 101a of the general-purpose device 10a distributes and outputs the command classification recognized in step S002 and each command recognized in step S003 to the corresponding functional unit 102a specified in step S004. do. Then, the process proceeds to step S006.
(Step S006) Each functional unit 102a of the general-purpose device 10a acquires the command classification and the command output from the common board unit 101a in step S005, respectively. Then, the process proceeds to step S007.

(Step S007) Each functional unit 102a of the general-purpose device 10a executes the command classification acquired in step S006 and the processing based on the command.
This completes the processing of this flowchart.

[Additional example of functional part in general-purpose device]
Hereinafter, a case where a new functional unit 102a is added to the general-purpose device 10a will be described with reference to the drawings.
FIG. 6 is a diagram for explaining a case where the functional unit 102a-3 is added to the general-purpose device 10a according to the first embodiment of the present invention. As shown in the figure, the management system 20a is connected to the general-purpose device 10a.

As shown in the figure, the configuration of the general-purpose device 10a and the management system 20a shown in FIG. 6 is the configuration in which the functional unit C102a-3 is added to the general-purpose device 10a in addition to the configuration described in FIG.

When the functional unit C102a-3 developed by the vendor Hei is added to the general-purpose device 10a and an instruction is given to the added functional unit C102a-3, the management system 20a sets the functional unit C102a as shown in FIG. After encapsulating the command for -3, the instruction data based on the instruction format f1 is generated, and the instruction data is transmitted to the common base unit 101a.
This makes it possible to newly add the functional unit C102a-3 without modifying the management system 20a.

Further, as shown in FIG. 6, the common base unit 101a previously displays information in which the command classification, the command, and the functional unit C102a-3 (which is the corresponding functional unit) are associated with each other in the setting information table t1. By registering, even if the command included in the instruction data includes the command for the functional unit C102a-3, the common infrastructure unit 101a can refer to the setting information table t1. It can be specified that the command is a command for the functional unit C102a-3. As a result, the common base unit 101a can also distribute and output the command classification and the command to the functional unit C102a-3.

As described above, according to the present invention, since the function of the access device is made into a software component and mounted on the general-purpose device 10a, the vendor lock-in is eliminated. For example, if the management system 20a for operation is also made into a software component in the same manner as this, the function of absorbing the vendor difference, which is conventionally provided in the operation system, becomes unnecessary, so that the development cost of the management system 20a is Can also be reduced. In this way, by converting the dedicated device into a general-purpose device and making the function into a software component, the vendor-dependent function can be minimized or eliminated.

Specifically, by converting the functions of the access device into software parts and building them on the general-purpose device 10a, it is not necessary to prepare a plurality of software parts having the same function in the same system (for example, XX-PON). The access device can be managed by the same management system 20a. Since there is no difference for each vendor such as the control setting, it is not necessary to prepare the management system 20a for each access device, and the cost can be reduced.

As described above, according to the first embodiment, maintenance and operation can be facilitated even if unique settings are required for each device.

<Second embodiment>
Hereinafter, a second embodiment of the present invention will be described.
Since the overall configuration of the general-purpose device and the management system is the same as that of the first embodiment described with reference to FIG. 3, the description thereof will be omitted.

[Functional configuration of general-purpose equipment and management system]
Hereinafter, the functional configurations of the general-purpose device and the management system will be described with reference to the drawings.
FIG. 7 is a diagram showing a functional configuration of a general-purpose device 10b and a management system 20b according to a second embodiment of the present invention. The description of the configuration common to the first embodiment will be omitted.
In a plurality of functional units 102b configured on the general-purpose device 10b, the communication protocol that can be used for setting the functional unit 102b may be limited to a specific communication protocol in advance. For example, as shown in FIG. 7, the functional unit B102b-2 is a functional unit that can be set only by the NETCONF communication protocol.

In the second embodiment, as shown in FIG. 7, in the storage unit 1011 of the common base unit 101b, the command classification, the command, the corresponding functional unit, and the communication protocol (OPENFLOW, NETCONF, etc.) are associated with each other. The set setting information table t2 is held in advance.

In addition, the common infrastructure unit 101b describes not only the communication protocol but also the information group (instruction set group) of various information used in the instruction given to each function unit 102b, the command classification, the command, and the corresponding function unit. And, may be stored in the setting information table t2 in advance in association with.

The common infrastructure unit 101b stores the corresponding functional unit and communication protocol in the storage unit 1011 of the common infrastructure unit 101b, which corresponds to commands and command classifications based on the instructions transmitted from the management system 20b to the functional unit 102b. It is specified by referring to the table t2.
Further, in the second embodiment, the common base unit 101b includes a function setting unit 1012. The function setting unit 1012 of the common base unit 101b performs a process of converting the command into a command conforming to the specified communication protocol, and then outputs (transfers) to the corresponding destination function unit 102b.

As a result, according to the second embodiment, even if the vendor of the functional unit 102b is different, the command is transmitted from the management system 20b to the general-purpose device 10b without modifying the management system 20b. be able to.
As described above, in the past, for example, the method of instructing the OLT from the management system was different between the OLT of the company A and the OLT of the company B, according to the present embodiment, on the virtualized OLT side. The difference in the method of the instruction can be absorbed. As a result, according to the present embodiment, the management system 20b can be integrated into one, so that maintenance and operation can be facilitated, and the installation cost of the device can be reduced.

As described above, according to the second embodiment, maintenance and operation can be facilitated even if unique settings are required for each device.

In the first embodiment and the second embodiment described above, the version of the management system (20a, 10b) is registered in advance in the setting information table (t1, t2) for each functional unit (102a, 102b). It may be done. The version registered here is the version of the management system required for each functional unit. If the instruction format differs depending on the version of the management system (20a, 20b), the general-purpose device (10a, 10b) converts the instruction format and sets each function unit (102a, 102b). May be done.
In addition, the version of the communication protocol such as OPENFLOW may be registered in the setting information table t1 (or the setting information table t2).

Even if each functional unit 102a (or each functional unit 102b) operates only in a specific version of the virtual machine, the version of the virtual machine is set to the setting information table t1 (or setting information table t2). The settings may be made after being registered in advance in the above and converted into instructions suitable for each virtual machine by the common base unit 101a (or the common base unit 101b).
Further, the common base unit 101a (or the common base unit 101b) manages which virtual OS each functional unit 102a (or each functional unit 102b) is operating from, and from the management system 20a (or the management system 20b). The acquired instruction data may be converted into an optimum frame based on the setting information table t1 (or the setting information table t2) and then output.

The common base unit 101a and the common base unit 101b described above may be realized by passing them to an agent according to the software architecture. The processing based on the present invention is possible if it is mounted in the same OLT or on different general-purpose devices. In the past, it was necessary to absorb the difference between functions for each vendor, but this makes it possible to absorb the difference on a general-purpose device.

In another embodiment, when it is desired to set the VLAN ID (Virtual LAN Identifier) of a specific ONU to "1" (that is, to set it to the default VLAN), conventionally, for OLTs with different vendors. It was necessary to set each individually, but according to the virtualization OLT according to the present invention, the setting can be reflected by a common command, so that the setting work is made more efficient.

In the above-described embodiment, the general-purpose device 10a (or general-purpose device 10b) including the functional unit 102a (or the functional unit 102b) is provided with the common base unit 101a (or the common base unit 101b). However, the present invention is not limited to this, and for example, only the functional range of the common base unit 101a (or the common base unit 101b) may be implemented as a dedicated device.

Even if it is a common instruction, it is converted into an instruction suitable for each functional unit 102a (or each functional unit 102b) in the common base unit 101a (or common base unit 101b). From the management system 20a (or the management system 20b), the communication protocol is the same, and only the instruction to each function unit 102a (or each function unit 102b) is transmitted.

Even if the instruction set is the same, the parameters are different, so that the management system 20a (or the management system 20b) may need to be set individually. As an implementation in this case, there is also a method of sniffing and converting a signal for virtualized OLT.

Although the embodiments of the present invention have been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and includes designs and the like within a range that does not deviate from the gist of the present invention.
