[0002] A network management system (NMS) is a system used to monitor, manage and maintain network devices and their connection status. Its main functions include network device configuration management, fault management, performance management, security management and billing management.

[0003] In the existing network management system, there is no good response measure for the scenario where there are various communication modes in the network. It only manages a single network mode. Various network links have different uses and are difficult to replace each other. In addition, each network protocol defines its own communication standard, which makes it impossible for devices between different networks to directly exchange data, resulting in a situation where heterogeneous networks operate independently. It is necessary to design a practical network management system to monitor heterogeneous network links.

[0004] The OpenWRT system has the advantages of low cost, high flexibility, wide compatibility, and scalability. It can adopt a heterogeneous network management system based on OpenWRT, which not only supports multiple network protocols, but also has powerful expansion capabilities. It can meet different network environments and management requirements, and as a solution based on an open source platform, it is gaining more and more attention. Summary of the invention

[0006] The data layer includes MongoDB and MySQL databases;

[0007] The management layer includes a system management module, a network management module and a link management module;

[0008] The application layer includes a data parsing module and a protocol conversion module, which are used to realize data exchange between different subnets;

[0009] The presentation layer provides a visualization module.

[0010] Furthermore, the system management module is used for network management server equipment information management, network management server status monitoring and network management server system log recording.

[0011] Furthermore, the system management module can add, delete, modify, check and save the configuration of the network management server, and has an alarm prompt function to provide feedback when an abnormality occurs in the server or system.

[0012] Furthermore, the network management module performs basic network parameter configuration according to the task scenario requirements, performs real-time monitoring of the global network topology and local network topology, and simultaneously performs real-time monitoring of subnets, node status, data traffic, and routing planning and routing strategy settings between communication nodes or subnets.

[0013] Furthermore, the link management module can perform access management and wireless resource management of link devices.

[0014] Furthermore, the link management module supports querying and configuring device firmware information, and can use a variety of methods to configure and optimize link operating parameters.

[0015] Furthermore, the functions of the visualization module include network configuration through human-computer interaction, network topology by displaying information connected to servers and nodes, log system display by writing information into the log system, and status display by displaying server device information.

[0016] Furthermore, the data layer is used to store device information status, add, delete, modify and check network device configuration parameters, and store and process historical data network logs.

[0017] Furthermore, the application layer supports a QoS-oriented information forwarding multi-route optimization mechanism for data parsing and protocol conversion between multiple heterogeneous networks.

[0018] Furthermore, the data exchange between different subnets of the application layer includes:

[0019] (1) The device in the source link transmits the data to the corresponding network management server system A through the corresponding interface. The network management server system A analyzes the data content in the source link through the data analysis module and parses the target address from the message content;
