Design And Implementation Of Wired Communication Network Management System Based On SNMP

With the rapid development of embedded technology and the increasing maturity of wired communication technology,a massive number of embedded devices have been deployed in wired communication networks,making the network complex and difficult to maintain,which in turn affects communication quality and network performance.Therefore,it is of great significance to efficiently manage network devices,accurately grasp the network operating status,and promptly discover and deal with security risks in order to ensure the stable and reliable operation of wired communication networks.This thesis aims to meet the needs of network management in a certain enterprise’s research and development project for wired communication network communication equipment,combining with Simple Network Management Protocol(SNMP)and key technologies of embedded development,a wired communication network management system based on SNMP was designed and implemented,mainly achieving three system objectives of network information management,network fault management,and visualization of human-computer interaction interface.Firstly,the development objectives of the network management system were proposed based on the network structure and characteristics of the wired communication network,and the functional and non-functional requirements were analyzed.Secondly,according to the analysis results,the management architecture and system architecture of the system were designed,and the modular design approach was applied to detail the various sub-modules of the system,including the private management information base(MIB),SNMP v3 security model,and database.Thirdly,the network management system consisting of server and client was implemented.The server utilized the Net-SNMP network management suite to develop and transplant the embedded SNMP agent software;the client software used Qt technology to build the SNMP management module and human-computer interaction interface,realizing a control software that integrates network management and information visualization.Finally,an actual test environment was set up to verify the main functions of the network management system.The test results demonstrated that each module functioned correctly and could achieve the predetermined development objectives.The wired communication network management system has already been put into use,which meets the needs of network management for the wired communication network communication equipment developed by the enterprise.It is of certain reference value for the future development of similar network management systems.
