Research And Implementation Of Visualized Management Of Campus Network Operation And Maintenance

With the continuous in-depth development of education informatization,almost all of the business of colleges and universities is carried out online,resulting in the continuous increase of equipment deployed on the campus network,and the types and selected manufacturers are also more diverse.This aspect has promoted the continuous development of campus networks and Technology updates,on the other hand,have also increased the load and complexity of the campus network.In daily operation and maintenance work,many devices only accept command line operations,which brings great difficulties to operation and maintenance personnel.The development of a system that can graphically manage all network devices on a unified platform can greatly reduce the workload of operation and maintenance personnel and greatly improve the efficiency of network operation and maintenance.In this regard,this article developed a network operation and maintenance management system based on the SNMP protocol.The system combines SNMP++ technology and MySQL database with a completely visual interface.The main work is as follows:(1)Collection of operating status information of network equipment.Through the development of SNMP++ technology,the functions of get,set and trap are realized,the information objects stored in the MIB library of the network equipment are collected,and the obtained information objects are stored in the database to facilitate the use and display of equipment status information.(2)Network topology discovery,through the collected equipment routing information,combined with the algorithm to discover the network topology,so as to facilitate the operation and maintenance personnel to understand the network connection.(3)The problem of redundancy of useless information and fusion and addition of useful information for different devices in the same system platform is solved,so that the situation that one system platform manages different devices and is difficult to manage information objects no longer occurs.(4)Graphically display and operate the operation and maintenance management work,so that part of the dynamically changing status information of the network equipment can be dynamically displayed graphically,and intuitively see the changes in the status information over a period of time,so that the equipment information is A more comprehensive understanding..The developed operation and maintenance management system realizes the operation and maintenance management of multiple types of equipment on a unified platform,and realizes the visual management of operation and maintenance operations and information viewing,which improves the efficiency of campus network operation and maintenance.
