technical field

The present application relates to the field of network operation and maintenance, and in particular to an operation and maintenance operation method, system and network equipment.

Background technique

Operators can automate network operation and maintenance management through the operation support system (OSS). However, network operation and maintenance management may have multiple scenarios. This is because the operation and maintenance operation of the same network management function can be realized through various technologies, such as network connectivity test operation, loop back (LB) through operation administration and maintenance (OAM) of Ethernet (ethernet) ) commands, link trace (LT) commands, and connectivity check (CC) commands can all be implemented, but there are differences in the command lines or docking interfaces corresponding to the same operation and maintenance operations on network devices in different fields. For example, there are differences between the network connectivity test commands of the access domain and the network connectivity test commands of the transport domain.

For example, network devices in different network domains or from different manufacturers have different input parameters, output parameters, and coordination parameters for the command line or interface of the same operation and maintenance operation. If a network includes network devices of multiple network domain types, it will result in the need to customize interfaces for various operation and maintenance operations on the network operation and maintenance system or OSS system. This leads to more complex implementation of operation and maintenance operations, and lower performance of its operation methods. Therefore, there is an urgent need for a general operation and maintenance operation method.

Application Scenario

As shown in FIG. 1 , it is a schematic diagram of a system architecture to which an operation and maintenance operation method provided in the embodiment of the present application can be applied.

The system architecture may include: an operation support system (operation support system, OSS), a first network device, and a second network device. In Fig. 1, the first network device takes a top-level controller (top-level controller, TC) as an example, and the second network device takes a domain controller (domain controller, DC) or an in-domain device (in-domain device, DD) as an example for illustration. The architecture can select the devices in the architecture according to specific scenarios. For example, the devices in the architecture can only include TC, DC, and DD, or can include OSS, TC, DC, and DD, and can also include OSS running devices (TC is a component of OSS) , DC and DD. The "domain" in the above description refers to a network area divided by a certain standard, such as a network area that uniformly uses a certain technology, then the network devices in this network area can achieve efficient intercommunication between network devices because there are no technical barriers.

Wherein, the functions of each device in the architecture may be: the OSS is used to deploy network services. For example, the OSS may deliver a service deployment request to the top-level controller by sending an OSS operation request to the top-level controller. Network services include network operation and maintenance services, such as connectivity detection services, which are used to detect connectivity between network devices. The top-level controller obtains the service request to be deployed by obtaining the first message. The first message may come from the service deployment configuration input by the user on the top-level controller interface. The first message may also come from a service request sent by a third-party system, for example, an OSS operation request sent by the OSS. The first message may be in the form of a message, such as a northbound interface message sent by the OSS. The first message indicates a first operation and maintenance operation, for example, the OSS requires the top-level controller to perform an operation and maintenance operation of path connectivity detection. In order to perform the operation and maintenance operation of the path connectivity detection described above, the top-level controller needs to send multiple operation and maintenance operations to multiple domain controllers and/or multiple intra-domain network devices under the top-level controller. The operation and maintenance operation of the path connectivity detection can be realized only after the above multiple operation and maintenance operations are executed. Then the first operation and maintenance operation includes the operation and maintenance operation that needs to be performed by the domain controller or the device in the domain. The first message acquisition method may be obtained according to the OSS operation request sent by the OSS running device, or may be obtained according to the local input information of the top-level controller. If the operation and maintenance operation commands or interfaces of the above-mentioned domain controllers or devices in the domain are different, the top-level controller needs to deploy operation and maintenance operations to the above-mentioned domain controllers or devices in the domain according to the operation and maintenance operation commands or interfaces. In this embodiment, the top-level controller converts the first operation and maintenance operation into the second message according to the conversion relationship between the first operation and maintenance operation and the operation and maintenance template. The second message may be in the form of a message, which may be called a southbound operation command or a southbound interface message. When the first message includes the first input parameter, converting the first input parameter into a second input parameter of an operation command specifying a domain. The second message includes a second input parameter. The top-level controller is also used to send the second message to a domain controller or an intra-domain device. The second message is used to invoke the domain controller of the specified domain to invoke an application programming interface (application programming interface, API) to execute the operation and maintenance operation corresponding to the API. The second message can also be used to deliver operation and maintenance operation configurations to domain controllers or devices in the domain based on network operation and maintenance protocols. Network operation and maintenance protocols include Netconf, SNMP, etc. or proprietary protocols, which are not limited here. The domain controller of the designated domain is configured to receive the second message and execute the operation and maintenance operation indicated by the second message. The domain controller of the designated domain is further configured to send the second message to the devices in the designated domain, and the devices in the domain implement service functions according to the second message. In some embodiments, after the controller of the designated domain executes the operation and maintenance operation indicated by the second message, it will send a response message of the second message to the top-level controller. The top-level controller obtains the response message and determines the execution status of the operation and maintenance operation according to the information carried in the corresponding message. When the response message includes the second output parameter, after the top-level controller receives the response message, the top-level controller converts the second output parameter into the first output parameter according to the operation and maintenance template.

It should be noted that the functions of each device in the above architecture are only examples, and the specific functions of each device can be flexibly adjusted according to actual application scenarios. For example, when processing the first message, the first output parameter may not be involved and the second output parameter, that is, after the device in the domain executes the operation command according to the second input parameter, it does not need to obtain the second output parameter, and the response message does not need to include the second output parameter.

Various operation and maintenance operations can be realized in this architecture. Since any operation and maintenance operation may have many different scenarios, the messages are also different. In the embodiment of this application, the operation and maintenance template corresponding to any operation and maintenance operation is pre-arranged. The conversion relationship required in various scenarios is defined. For example, the operation and maintenance template includes the conversion relationship between the first input parameter and the second input parameter, and the conversion relationship between the first output parameter and the second output parameter. In this way, regardless of the first message in any scenario, both the top-level controller and the domain controller can receive the first message through a unified interface, and perform corresponding processing step by step according to the operation and maintenance template and the first message. It should be noted that after the top-level controller converts the first message into the second message, the second message can be executed directly when it arrives at the device in the domain, so that the device in the domain can implement operation and maintenance operations. When it comes to cross-domain scenarios, you can Break through the technical barriers between different technical domains through the conversion of the top-level controller.

In addition, for the second operation and maintenance operation that needs to be performed, the second network device involved can preload the second operation and maintenance operation, so that the second network device (such as a device in the domain) can receive the corresponding second operation and maintenance operation , it can be determined that it is the second operation and maintenance operation of pre-mounting, and then the second operation and maintenance operation can be executed. The services realized by the above architecture can be intra-domain services or cross-domain services. For intra-domain services, intra-domain devices performing service functions only involve intra-domain devices in one network area; for cross-domain services, intra-domain devices performing service functions need to involve intra-domain devices in multiple network areas. For example, for the architecture shown in Figure 2, if the connectivity detection is performed in a local area network, then the second operation and maintenance operation of the connectivity detection needs to be mounted in this local area network, so that the second operation and maintenance operation of the connectivity detection is in The execution in the local area network is legal. When the OSS outputs an OSS operation request for connectivity detection to the top-level controller, the top-level controller converts the first input parameter of the connectivity detection in the OSS operation request into connectivity by executing the OSS operation request. The second input parameter detected, and then the domain controller sends the second input parameter of connectivity detection to the devices in the local area network, and the second input parameter is included in the second message of connectivity detection, then the devices in the local area network will According to the second input parameter, the operation command of connectivity detection can be successfully executed; for cross-domain services, such as Internet packets between passive optical network (passive optical network, PON) and optical transport network (optical transport network, OTN) The explorer (packet internet groper, PING) operation can be realized through the link trace (LT) technology, then it is necessary to mount the respective second operation and maintenance operation (LT operation command) in both the PON domain and the OTN domain , so that the execution of the second O&M operation in both the PON domain and the OTN domain is legal. When the OSS needs to perform link tracking between the PON domain and the OTN domain, it will issue the second Second operation and maintenance operation (may include the corresponding second input parameter of LT), the intra-domain devices in the PON domain and OTN domain execute the corresponding link tracking operation command to realize the link tracking function between the PON domain and the OTN domain.

More specifically, a schematic diagram of the software architecture inside the top-level controller in FIG. 1 or FIG. 2 is shown in FIG. 3 . Specifically, the top-level controller can include the following software modules:

(1) Business logic processing system, including the following components:

The service designer is used to bind the operation and maintenance template and the business model, and generate operation application strategies, which are used to control network operation and maintenance operations in different situations. The business model is the model of the encapsulated network operation and maintenance function, which is used to realize the general network operation and maintenance function. The business model can combine different application scenarios of an operation and maintenance operation together.

A northbound application programming interface (application programming interface, API) is used to receive the first message, such as an OSS operation request, and trigger the operation executor to generate the first operation and maintenance operation according to the operation application policy.

A business graphical user interface (graphical user interface, GUI) is configured to receive a first message, such as a user operation request, and trigger an operation executor to execute and generate a first operation and maintenance operation according to an operation application policy.

Logic processor: used to perform business logic processing according to the set business logic.

(2) The operation designer is used to generate operation and maintenance templates according to operation requirements, and manage operation and maintenance templates through the operation and maintenance template library.

(3) The operation and maintenance template library is used to maintain the operation and maintenance template, wherein the maintenance includes storing, modifying, querying and adding the operation and maintenance template, etc.

(4) The operation executor is used to generate the second message according to the operation and maintenance template, display the input interface and output interface, receive the request, and display the processing result, and is also used to analyze the content of the first message according to the definition of the parameter model in the operation and maintenance template The parameters are input and passed to the southbound adapter module, distributed to each domain controller, and used to parse and display the return of each domain controller according to the definition of the output parameter model in the operation and maintenance template.

(5) Southbound adaptation module, used for communication protocol conversion with each domain controller.

It should be noted that the software architecture of the top-level controller shown in FIG. 3 is only an example, and various software modules can be flexibly organized and functions of each software module can be designed, which is not limited here.

Step 401: Arranging an operation and maintenance template for operation and maintenance operations.

Step 402: Bind the operation and maintenance template of the operation and maintenance operation to the business object, and set the operation application strategy.

Step 403: Execute operation and maintenance operations.

In step 401, for example, the operation and maintenance operation is a PING operation from the PON device to the OTN device, and the PING operation can be implemented by using the LT technology.

The O&M template includes: O&M operation identifier, operation application policy, and basic operation information.

Wherein, the operation and maintenance operation identifier is used to indicate the operation and maintenance operation, and also identifies an operation and maintenance template. The operation and maintenance operation identifier includes but is not limited to the name of the operation and maintenance operation, the sequence number of the operation and maintenance operation, etc.

The operation application strategy refers to the situation where the operation is applicable. The operation application strategy can include the operation and maintenance operation mode. The operation and maintenance operation mode refers to the execution flow mode of the operation and maintenance operation, including synchronous mode, asynchronous mode and reporting mode. The network equipment for maintenance operation needs to wait for the response message (response message) of the operation message (second message) until it receives the response message before performing other operation and maintenance operations; in asynchronous mode, the operation and maintenance operation The network device can execute other operation and maintenance operations asynchronously while waiting for the response message of the operation message; Need to wait for the response message. The operation application policy can also include a business object, which specifies the equipment for which the operation and maintenance template takes effect; the operation application policy can also include information such as the type of equipment, the version of the operation and maintenance operation, and other operational adaptation situations.

Wherein, the input parameter model includes a southbound model and a northbound model defining the input parameters of the operation, the northbound model of the input parameters is the message body model of the input parameters, and the southbound model of the input parameters is used to indicate the first operation and maintenance operation The conversion relationship between an input parameter and the second message, such as the model of the input parameter to the specified message body of the external system, for example, in the top-level controller, the first input received by the top-level controller can be realized based on the mapping file The parameter conversion is to satisfy the second input parameter of the domain controller, that is, the output message of the top-level controller, and the format of the output message is to meet the specified format required by the input message of the domain controller (that is, the format of the second input parameter ); correspondingly, the output parameter model is similar to the input parameter model, and the output parameter model can refer to the description of the input parameter model, and the output parameter model is used to indicate that the first output parameter of the first operation and maintenance operation is different from the second operation and maintenance operation The conversion relationship of the second output parameter of the operation will not be repeated here. It should be noted that the input model or the output model does not have to be included. The operation and maintenance template of the operation and maintenance operation can only have the input model but no output model, and some operation and maintenance operation templates can also only have the output model. Participating in the model but not in the participating model, or both, and neither, there is no limitation here, and it needs to be designed according to the operational characteristics of the operation and maintenance operation. Both the input parameter model and the output parameter model can flexibly select the specific data definition format, such as the JsonSchema definition format, or the mapping file, which can map the input operation message to the second input parameter in the format specified by the domain controller. The mapping file can be Implemented using FreeMarker extended syntax. The design of the operation and maintenance template can be completed through the online system, and stored in the operation and maintenance template library, the validity of the operation and maintenance template can be verified, and the operation and maintenance template can be released.

Specifically, take the PING operation from the PON device to the OTN device as an example. The PON device and the OTN device need to define two O&M templates respectively, and use different operation and application strategies to control the application of different O&M templates in different technical fields. Taking the PON device side as an example, the operation name is PING, and both OSS and GUI perceive the PING operation of the common interface. The operation and maintenance template can be defined through the Json file, and the structure of the operation and maintenance template can be as follows:

Template identifier (id), operation application strategy (commandRestraint), and basic operation information (commandBasciInfo); the basic operation information includes: operation name (operationName), input parameter model (commandConfigure) and output parameter model (commandStatus).

A sample of the O&M template is as follows:

It should be noted that in the structure of the above template example, some variables may include multiple layers, and the content in "{}" and \ or "[]" after the variable indicates the specific definition of a variable, and the variable can also be nested Variables, that is, variables described with "{}" and \ or "[]" can also include variables described with "{}" and \ or "[]", such as "rootRestraints" and "applyObjects" in commandRestraint , and each variable defined in "{}" and \ or "[]", the scope of its value is only within the "{}" and \ or "[]", such as "value in "commandConfigure" ", its scope is only in "commandConfigure", the scope of "value" in "commandStatus" is only in "commandStatus", the Chinese characters in the above template samples are all code comments.

As can be seen from the above O&M template sample, where id is the template identifier of the O&M template. In the example, the value of id is "NCEFANEthernetOamLTCommandTemplate ID"; description is the description of the O&M template, which is used to describe the operation and maintenance template The business function realized; operStatus is the release status of the operation and maintenance template, which can be deployed (deployed) or undeployed (undeployed); commandRestraint is the operation application strategy, in which rootRestraints defines the applicable application scenarios of the operation and maintenance operation, "scenario ":"OTN_P2MP" indicates that the operation and maintenance template is applied to the OTN domain and the point-to-multipoint master (point 2 multiple point, P2MP) technology, "subScenario":"TP" indicates Termination Point, and the description of this operation is for the port level Yes, vendors is the manufacturer, device type and version information that the operation and maintenance operation can run, processMode is the operation mode, "syncMode" in the sample indicates the synchronization mode, applyObjects is the application object of the operation and maintenance operation, "objectType" is the object type, " "COMPOSED-AC" means the combined service access point, means the access point of the end-to-end business, "validScopes" means the detailed operation application constraints, validScopes is a list of name-value pairs, "name" in "validScopes" is the parameter name, "workingLayer" indicates the working layer, which refers to the layer where this operation takes effect, "value" in "validScopes" is the parameter value, and "LR_Ethernet" indicates that the Ethernet service is allowed to start. If the working mode of the access point is not Ethernet, it is not allowed to start this command; commandBasicinfo is the basic information of the operation, and operationName is the general operation name. For example, the manufacturer’s connectivity detection operation is Ethernet OAM LT operation, but the operation name (operationName) is uniformly packaged as PING (transmission, access, and data communication), and the operationName can be "PING" at this time; commandConfigure is an input parameter model, and "name" in commandConfigure points to the name of a specific input parameter model. The input model is implemented through the input definition component and component mapping file, and the "value" in commandConfigure is the unique ID corresponding to the input template. Specifically, an example of defining a component structure can be as follows:

Defining the component structure may include two parts: a component template and a component mapping file, wherein the component template describes the input and constraints of parameters through JsonSchema.

Specific examples of component templates are as follows:

Component mapping file: it is to translate the first message (northbound interface message) into the second message (southbound interface message) input to the domain controller. The sample fragment is as follows:

The input parameter model is defined through commandConfigure, the output parameter model is defined through commandStatus, and the northbound interface component name points to a northbound interface component and mapping file defined by JsonSchema. The JsonSchema defines the necessary input parameters for the PING operation, such as the identity of the source end maintenance entity group end point (MEP), the time to live (Time To Live, TTL) and other values; the "name" in the output parameter model (commandStatus) ", "value" are similar to commandConfigure, you can refer to the description of the input parameter model.

By arranging operation and maintenance templates, any operation and maintenance operation can be abstracted into a scalable general operation and maintenance template, and the development workload of operation and maintenance operations can be greatly reduced by arranging operation and maintenance templates in real time. This is because the situation in each scenario is abstracted through the operation and maintenance template, and the interface, input parameters, output parameters, and different operation modes in different scenarios will be automatically generated in the operation and maintenance template, without repeated arrangement in each scenario, so The workload will be reduced. The operation mode can be abstracted into a synchronous interface for general operations and an asynchronous interface for operations. The application logic obtains the process mode from the operation and maintenance template, calls the unified synchronous interface or asynchronous interface, and uses the mapping file of the bound business object in the unified interface. The first input parameter is converted into the second input parameter, and the second output parameter is converted into the first output parameter. By associating the operation and maintenance template with the operation application strategy, the service-level abstract interface is provided to the OSS.

In step 402, the service object may include each access point (for example, two access points) realizing the service connection and a network path between the access points. If the operation and maintenance template of the operation and maintenance operation is directly bound to the business object, then since the operation and maintenance operation of a business requires the cooperation of each access point, the operation and maintenance operation will be decomposed into operation commands on each access point, O&M operations need to be performed on each access point. For example, each access point is specifically a designated PON device in the PON domain and a designated OTN device in the OTN domain. The operation and maintenance operation is a node activation operation, and the node activation operation is to register a node in a designated network area. In this example, If you specify a PON device and a designated OTN device, when the node activation operation is executed, the corresponding node activation commands need to be executed synchronously on the designated PON device and the designated OTN device respectively.

The business object can also be only the access point, so the operation and maintenance operation can only be initiated by a certain access point without synchronous execution. For example, if the operation and maintenance template is bound to the specified PON device and the specified OTN device, and the operation and maintenance operation is a delay detection operation, then the delay detection command (southbound operation command) can be initiated from the specified PON device, and the specified The PON device side only needs to wait for the response from the designated OTN device, and can initiate a delay detection command (southbound operation command) from the designated OTN device, and the designated OTN device side only needs to wait for the response from the designated PON device.

It should be noted that how the above operation and maintenance operations are performed in different situations is constrained by the operation and maintenance operation policy. Before the top-level controller converts the first message into the second message, it is necessary to judge whether the OTN device and PON device have enabled the corresponding operation and maintenance operation through the operation and maintenance operation strategy. The operation and maintenance operation strategy of the operation and maintenance template also includes business objects. In the business object, one end and multiple ends can be specified, and the operation and maintenance operation strategy can also specify the effective device type, the effective version of the specified operation command, etc., which can be flexibly designed according to the specific operation and maintenance operation; among them, for the division of source and sink One-segment business, one-segment validation can be effective at the source end and the sink end, and multi-terminal activation can be effective at both ends.

In the example of the PING operation from the PON device to the OTN device, the operation and maintenance operation strategy can be defined through the Json file. Specifically, the operation and maintenance operation strategy can be as follows:

Among them, CommandTemplate is the operation and maintenance template identifier, which is used to bind the operation and maintenance template name; CommandOperateName is the name of the operation command displayed corresponding to the operation and maintenance operation; GUIHookPoint is the interface hanging node, which is used to indicate the business object mounted by the operation and maintenance operation; ValidObjectCfg is the operation validation strategy, specifying the source to take effect; BindingBusinessObjects is the application object, which is used to control which business objects the operation and maintenance template takes effect on, and fdName is specifically the name of the bound business object.

An example of an operation and maintenance operation policy is as follows, which may specifically include the following fields:

The following takes the first network device as the top-level controller as an example and the second network device as the domain controller as an example to describe in detail the process of step 403 when the top-level controller controls any designated domain to perform operation and maintenance operations. For specific steps in 403, reference may be made to FIG. 5 , which is a specific flowchart for performing operation and maintenance operations.

Step 501: The top-level controller obtains the first message.

Specifically, the first operation and maintenance operation may be an operation in a single domain or a cross-domain operation, the first message indicates the first operation and maintenance operation, and the first operation and maintenance operation includes the need for the second network device The second operation and maintenance operation is performed, the second operation and maintenance operation is obtained according to the first operation and maintenance operation and the operation and maintenance template, and the execution of the second operation and maintenance operation by the second network device can be performed by the second The message indicates that the operation and maintenance template includes an operation and maintenance operation identifier and a conversion model, the operation and maintenance operation identifier indicates the first operation and maintenance operation, and the conversion model indicates the relationship between the first operation and maintenance operation and the second operation and maintenance operation. The conversion relationship of the dimension operation.

It should be noted that the first message may include the first input parameter. If the operation and maintenance template corresponding to the operation and maintenance operation includes the input parameter model, then the first input parameter needs to be obtained according to the specification in the input parameter model. When obtaining the first input parameter, in step 501, the operation interface of the client may be generated according to the input model in the operation and maintenance template of the operation and maintenance operation, and the first input parameter of the operation and maintenance operation may be determined according to the input information of the operation interface of the client. As shown in Figure 6, according to the JsonSchema definition of the input parameters, a Json operation interface can be generated to obtain the input information of the Json operation interface, or the top-level controller can also extract operation The first input parameter of the dimension operation; step 501 can be implemented by the operation executor in FIG. 3 .

Step 502: The top-level controller determines whether the operation and maintenance operations executable by the domain controller include the second operation and maintenance operation according to the operation and maintenance operation policy.

If yes, execute step 503; otherwise, end the process directly.

Step 503: the top-level controller generates a second message according to the first message, and determines the operation mode in the operation and maintenance template.

For example, the first message is an OSS operation request, which is directly converted into a Json message according to the input parameter model model. The details of the Json message can be as follows:

CommonCommand

operationName: ping

commandConfigure hanging node

|--name:PONEthernetOamLTCfg

|--value: "{{\"remoteMepId\":2,\"ttl\":62}}"

Among them, commandConfigure is the input parameter model, PONEthernetOamLTCfg indicates that, remoteMepId indicates the ID of the remote MEP point, and TTL indicates that the lifetime is 62 milliseconds (ms).

Specifically, when the pending operation request includes the first input parameter, the top-level controller can convert the first input parameter into the second input parameter according to the mapping file of the input parameter model in the operation and maintenance template, and according to the second input parameter A southbound interface message is generated, and the format of the second input parameter in the southbound interface message is the specified format required by the domain controller for input parameters; step 502 can be implemented by the operation executor in FIG. 3 .

If the operation mode is synchronous mode, execute step 504; if the operation mode is asynchronous mode, execute step 505; step 503 can be implemented by the logical processor in FIG. 3 .

Step 504: the top-level controller sends the southbound interface message to the designated domain controller, and waits for a response message of the southbound interface message.

If the response message is obtained, go to step 507.

Step 505: the top-level controller sends the southbound interface message to the designated domain controller, and obtains the task identifier.

The task identifier is used to mark the domain controller as a task for processing southbound interface packets.

Step 506: The top-level controller waits for the response message of the southbound interface message according to the task identifier.

If the response message is obtained, go to step 507. It should be noted that, when step 506 is executed, the top-level controller may also execute other operations in parallel.

Step 507: The top-level controller performs further processing according to the response message.

If the operation and maintenance template of the operation and maintenance operation includes the output parameter model, the devices in the domain will get the second output parameter. If the operation and maintenance template of the operation and maintenance operation includes the input and output parameter model, the devices in the domain can get the second output according to the second input parameter parameter, in this case, the response message will include the second output parameter, then the top-level controller can convert the second output parameter output by the domain controller into the first northbound output parameter according to the mapping file of the output parameter model, The format of the first output parameter conforms to the specified format required by the OSS, so that the first output parameter can be returned to the OSS or the operation interface output of the client.

The following is described with a more specific example. For example, the operation and maintenance operation is the PING operation from the PON device to the OTN device on the PON device. The PING operation can be realized through the LT command. The operation and maintenance template of the PING operation includes an input parameter model and an output parameter model. . The specific steps can be shown in Figure 6, specifically as follows:

Step 601: The top-level controller obtains the northbound interface message of the PING operation.

For example, the top-level controller can generate a Json view interface of the client according to the JsonSchema definition of the input parameter model of the PING operation, and directly convert the input information of the client's operation interface into a northbound interface message in Json format, and the northbound interface The message includes the first input parameter.

Step 602: The top-level controller converts the northbound interface packet into the southbound interface packet.

For example, the top-level controller converts the first input parameter into the second input parameter through the mapping file of the input parameter model. The second input parameter is the format of the input parameter required by the domain where the PON device is located. The second input parameter is included in the to the interface message.

Step 603: The top-level controller determines that the operation mode defined in the operation and maintenance template of the PING operation is a synchronous mode.

It should be noted that, here, it is determined that the operation mode defined by the PING operation is the synchronous mode, and then step 604 is executed. If the defined operation mode is not the synchronous mode, there may be other branches.

Step 604: The top-level controller sends the converted southbound interface message to the domain controller where the PON device is located through the southbound adaptation module, and waits to obtain a response message.

Step 605: the domain controller sends the southbound interface message to the PON device.

It should be noted that, in this example, it is pre-determined that the PING operation is the operation and maintenance operation on the PON device, so step 605 is executed. However, in some other situations, the domain controller may also determine that the southbound interface report If the operation and maintenance operation corresponding to the document is the operation and maintenance operation on the domain controller, then the southbound interface packet is directly executed to realize the operation and maintenance operation on the domain controller.

Step 606: The PON device executes the southbound interface message, and obtains the second output parameter according to the second input parameter.

Wherein, the second output parameter is included in the response message.

Step 607: the PON device sends the response packet to the domain controller.

Step 608: the domain controller sends the response packet to the top-level controller.

Step 609: The top-level controller converts the second output parameter into the first output parameter according to the mapping file of the output parameter model of the PING operation.

After step 609, the top-level controller may convert the first output parameter into OSS or output it on the operation interface of the client.

The above method only needs to update the operation and maintenance template to realize the online expansion function of the operation and maintenance operation, without reloading the program package, and realizes version-free release. The above method implements a technology for building an ecology. OSS and clients do not need to understand complex processing logic. They only need to arrange operation and maintenance templates according to this kernel framework to obtain various operation and maintenance functions of cross-domain business, thereby solving cross-technical domain The end-to-end operation and maintenance function can quickly adapt to the special requirements of different technical domains, and solve the current cross-technical end-to-end operation and maintenance shortcomings.
