Description

Technical Field

[0001] This invention relates to the field of network management software technology, and in particular to a virtual agent network management system based on the SNMP protocol and its construction method. Background Technology

[0002] Currently, almost all network communication devices have Simple Network Management Protocol (SNMP) network management functionality. An SNMP network management system consists of a Network Management Station (NMS) and a SNMP Agent running on the managed device. The SNMP Agent and the NMS communicate using the standard SNMP protocol. The SNMP network management system and its construction method can perform functions such as configuration management, performance management, and fault management for the managed device.

[0003] Generally, SNMP agents run on devices to manage device information and respond to network management requests. However, in actual development, there are often situations where there is a need for networking a large number of devices; network management developers cannot obtain usable devices in a short time; or the devices are too expensive for network management developers to learn how to use. How to conduct related business without devices has become an urgent technical problem to be solved. In "Design and Implementation of SNMP-based Network Management Agent Simulation Software," Wang Lide proposed an SNMP-based agent software for testing network management information in the absence of devices.

[0004] While the aforementioned research can test the SNMP information transmission and reception of network management systems without the need for equipment, the service relies heavily on human-computer interaction, has a low degree of automation, and cannot simulate real business scenarios. Summary of the Invention

[0005] The purpose of this invention is to provide a virtual agent network management system and its construction method based on the SNMP protocol, which aims to solve the problems of network management services relying on human-computer interaction, low automation, and inability to simulate real business scenarios.

[0012] The service mapping module is used to map SNMP requests to the corresponding services to ensure that the requests can obtain the correct request data.

[0013] The data features include table name, field name, field type, and OID information.

[0014] The business adjustment service subsystem includes a construction request service module, a business parameter configuration service module, and a response request module, which are connected sequentially.

[0015] The construction request service module is used to receive requests to modify business parameters and obtain modification requests;

[0016] The business parameter configuration service module modifies the business parameters based on the modification request, implements the parameter processing logic in this embodiment of the invention, and persists it to the database;

[0034] Please see Figure 1 In a first aspect, the present invention provides a virtual agent network management system based on the SNMP protocol, including a virtual agent service subsystem 1 and a service adjustment service subsystem 2, wherein the virtual agent service subsystem 1 and the service adjustment service subsystem 2 are connected.

[0035] The business adjustment service subsystem 2 is used to modify business parameters and provide diverse simulation data for SNMP network management.

[0036] The configuration file module 11 is used to indicate the data characteristics of the current business;

[0037] The database module 12 is used to persist all business data, replacing the MIB file in the device for use by the agent;

[0038] The data object module 13 is used to receive data queried from the database module 12;

[0040] The service mapping module 15 is used to map SNMP requests to the corresponding services to ensure that the requests can obtain the correct request data.

[0041] In this embodiment of the invention, the business adjustment service subsystem 2 is used to modify business parameters and provide diverse simulation data for SNMP network management; the virtual agent service module, running on a server or personal computer, provides agent services for SNMP network management. Specifically, the configuration file module 11 is used to indicate the data characteristics of the current business, the database module 12 is used to persist all business data, replacing the MIB file in the device for agent use, the data object module 13 receives data queried from the database module 12, the data processing module 14 is used to process the data in the database module 12 and special business data processing, and the service mapping module 15 is used to map SNMP requests to the corresponding services to ensure that the requests can obtain the correct request data.

[0042] Furthermore, the business adjustment service subsystem 2 includes a construction request service module 21, a business parameter configuration service module 22, and a response request module 23, which are connected in sequence.

[0047] Please see Figures 2 to 7 Secondly, the present invention also provides a method for constructing a virtual agent network management system based on the SNMP protocol, applied to the virtual agent network management system based on the SNMP protocol as described in the first aspect above, characterized by comprising 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 this embodiment of the invention, unlike real business operations, a proxy service runs on the device and manages the data within the device. The proxy service is a virtual service that runs on a personal computer or server and stores device information through the database module 12 to simulate real device data. This simulated data stored in the database is used for network management development and testing. The configuration file module 11 is used to store the data characteristics of the current business, characterized by information such as the table name, field name, field type, and OID of the business data, which are used by the proxy service to verify whether an SNMP request belongs to the current business and to encapsulate the data information.

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

[0051] In this embodiment of the invention, the data object module 13 is used to receive data objects from the database. The data processing module 14's data processing process includes, but is not limited to, querying, modifying, and restricting data modification. The data processing also includes join queries and modifications. It performs corresponding data processing according to business requirements. The configuration file refers to the configuration file in step S1, and service mapping refers to mapping the received SNMP request to the corresponding data processing based on the carried OID information.

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

[0053] In this embodiment of the invention, taking the construction of an HTTP request by a web browser as an example, a web service is constructed to receive requests to modify parameters. CRUD operations are performed on the data in the database according to actual needs. The HTTP request and response data are in JSON format.

[0054] To better understand this technical solution, the following embodiments are provided for further explanation:

[0055] Example 1

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

[0057] S1: Build the database;

[0058] S2: Build the configuration file;

[0059] S3: Construct data objects;

[0060] S4: Complete the data processing process;

[0061] S5: Build the service mapping module 15.

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

[0063] In step S2, the example uses JSON format to construct the configuration file. The configuration file design should provide table names and table OID information. The table name is used to retrieve the OID information of the current group, and the table OID is used to determine whether the current service request is legitimate. The `deviceAttribute` table should contain five attributes: `name`, `serialNo`, `type`, `manufacture`, and `comment`, consistent with the fields in the database design, and specify 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 legitimate; the field name and field type are used for data decomposition and encapsulation; and whether the field is read-only is used to determine whether the current service's request for the field is legitimate.

[0064] In step S3, the data object is used to receive data objects from the database. The type and name of the data are known through the configuration file. A DeviceAttribute object is constructed, which contains five variables: name, serialNo, type, manufacturer, and comment. The variable types are 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 includes, but is not limited to, adding, deleting, modifying, querying, and joining data in the database. It also includes data initialization and data processing triggered during use.

[0066] In step S5, service mapping refers to mapping the received SNMP request to the corresponding data processing service based on the OID information it carries. Data processing involves constructing the data processing service in step S4. Upon receiving an SNMP request, the request data is first parsed to obtain the OID information carried in the request; then, the service requested is determined based on the OID and the service mapping table, and the corresponding data processing service is entered; finally, the obtained data is encapsulated and the SNMP request is responded to.

[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 management system sends an SNMP request. The virtual service then captures the SNMP request and verifies its validity according to the configuration file. If the verification fails, it responds with an error SNMP message. If the verification is successful, it finds the corresponding service using the service mapping function in step S5, processes the data using the data processing service in step S4, and finally encapsulates the data and responds with an SNMP message.

[0068] To address the needs of different business operations, this invention provides a function for flexibly modifying business parameters. The process for modifying business parameters is described below. Figure 6 Schematic diagram of proxy service business adjustment. The network management system sends HTTP requests based on business parameter configurations. The service receives the corresponding requests, distributes them to different services according to the request parameters, and finally adjusts the business data, encapsulates the data, and responds to the HTTP request.

[0069] S6: Build the request service;

[0070] S7: Build parameter processing services based on business requirements;

[0071] S8: Response to the 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 requests to modify parameters.

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

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

[0075] The above description is merely a preferred embodiment of the virtual agent network management system and construction method based on the SNMP protocol of the present invention. Of course, it should not be construed as limiting the scope of the present invention. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of the present invention still fall within the scope of the invention.
