[0002] At present, almost all network communication equipment has the Simple Network Management Protocol SNMP, that is, Simple Network Management Protocol network management function. The SNMP network management system consists of a network management workstation NMS, that is, Network Management Station and a network management agent SNMPAgent running on the managed equipment. The SNMPAgent and NMS communicate through the standard SNMP protocol. The SNMP network management system and its construction method can complete functions such as configuration management, performance management and fault management of the managed equipment.

[0047] See also Figures 2 to 7 In a second aspect, the present invention further provides a method for constructing a virtual agent network management system based on the SNMP protocol, which is applied to the virtual agent network management system based on the SNMP protocol as described in the first aspect above, and is characterized in that it includes the following steps:

[0048] S01 database module 12 builds a database based on actual needs, and configuration file module 11 builds a configuration file based on actual needs;

[0049] In the embodiment of the present invention, unlike the real business, the proxy service is run in the device and manages the data in the device. The proxy service is a virtual service that runs in a personal computer or server, and saves device information through the database module 12 to simulate real device data. These simulated data saved in the database are used for network management development and testing. The configuration file module 11 is used to save the data characteristics of the current business, characterized in that the table name, field name, field type and OID of the business data are used by the proxy service to verify whether the SNMP request belongs to the current business and encapsulate the data information.

[0050] S02 constructs the data object module 13 based on the database and the actual demand, the data processing module 14 completes data processing based on the actual demand, and constructs the service mapping module 15 based on the configuration file;

[0051] In the embodiment of the present invention, the data object module 13 is used to receive the data object of the database, and the data processing process of the data processing module 14 includes but is not limited to querying, modifying and limiting data modification, and the data processing also includes joint table query and modification. And the corresponding data processing is performed according to the business requirements. The configuration file refers to the configuration file in step S1, and the service mapping refers to mapping the request to the corresponding data processing according to the OID information carried after the SNMP request is received.

[0052] S03 constructs a request service through the construction request service module 21, and then processes the service based on the business construction parameters through the business parameter configuration service module 22. Finally, the response request module 23 responds to the request.

[0053] In the embodiment of the present invention, a web browser constructs an HTTP request as an example to construct a web service for receiving a request to modify parameters. Add, delete, modify, and query data in the database according to actual needs. The HTTP request response data adopts the JSON format.

[0054] In order to better understand the present technical solution, the following embodiments are provided for further explanation:

[0055] Embodiment 1

[0056] This embodiment provides a technical solution: a design of an SNMP-based proxy service, including the following steps:

[0057] S1: build database;

[0058] S2: build configuration file;

[0059] S3: construct data object;

[0060] S4: Complete the data processing process;

[0061] S5: Construct service mapping module 15.

[0062] In step S1, a database table deviceAttribute is constructed based on known information, and the type and size of each field are specified. Figure 4 Database design.

[0063] In step S2, the case uses the JSON format to construct a configuration file. The configuration file design should provide table name and table OID information. The table name is used to obtain the OID information of the current group, and the table OID is used to determine whether the current request service is a legal request. The deviceAttribute table should contain five attribute information: name, serialNo, type, manufacturer, and comment, which should be consistent with the fields in the database design, and indicate the OID information, field name, field type, and whether the field is read-only for each field. The field OID information is used to determine whether the requested field OID is legal. The field name and field type are used for data disassembly and encapsulation. Whether the field is read-only is used to determine whether the current service request for the field is legal.

[0064] In step S3, the data object is used to receive the data object of the database. The type and name of the data are known through the configuration file, and a DeviceAttribute object is constructed, which includes five variables: name, serialNo, type, manufacturer and comment, and the variable type is specified. The name and type of the data object should be consistent with the name and type in the database.

[0065] In step S4, the data processing process includes but is not limited to adding, deleting, modifying, checking and linking table processing of data in the database, and also includes data initialization processing and data processing triggered during use.

[0066] In step S5, service mapping refers to mapping the received SNMP request to the corresponding data processing according to the carried OID information, and the data processing is to build the data processing service in step S4. When the SNMP request is received, the request data is first parsed to obtain the OID information carried in the request; then the currently requested service is determined according to the OID and the service mapping table, and then the corresponding data processing service is entered; finally, the obtained data is encapsulated and responded to the SNMP request.

[0067] After the service is built, the SNMP agent service process is as follows Figure 5As shown. After starting the virtual agent service, the network manager sends an SNMP request, and then the virtual service captures the SNMP request and verifies whether the request is reasonable according to the configuration file. If the verification fails, it responds with an error SNMP message. After the verification is successful, the corresponding service is found according to the service mapping function in step S5, and then the data is processed according to the data processing service in step S4, and finally the data is encapsulated and the SNMP message is responded.

[0068] In order to meet the needs of different services, the present invention provides a function of flexibly modifying service parameters. Figure 6 Schematic diagram of proxy service business adjustment. The network management sends HTTP requests through business parameter configuration. The service receives the corresponding request and distributes it to different services according to the request parameters. Finally, the business data is adjusted, the data is encapsulated and the HTTP request is responded.

[0069] S6: build request service;

[0070] S7: Processing services according to business construction parameters;

[0071] S8: Response request.

[0072] In step S6, taking the construction of an HTTP request by a WEB browser as an example, a WEB service is constructed to receive a request for modifying parameters.

[0073] In step S7, add, delete, modify and query the data in the database according to the requirements.

[0074] In step S8, the HTTP request is responded to, and the response data is encapsulated in JSON format. The response data includes a status code, response information, and response data.

[0075] The above disclosure is only a preferred embodiment of a virtual agent network management system and construction method based on the SNMP protocol of the present invention. Of course, this cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
