Design And Implementation Of B/S Based Network Equipment Monitoring And Management System

The booming of Internet has not only raised new demands for network management technology but also provided new methods to realize it.B/S structure is gradually replacing C/S structure and WBM is becoming a new trend.Data visualization offers a better way to understand the massive data brought about by the Internet.This system set forth from three aspects--the monitoring of network conditions,the management of network configuration and the monitoring of network devices--to improve the stability of the system.With the visualization tools such as D3 and Echarts,the system can realize visual display of network data and alarm and troubleshoot network anomalies.To improve the situation of configuration file massiveness,high content coupling,high requirement for operator and error-proneness,the files are converted into abstract data structures,replacing direct human-modification with editable tables which analyze the content of the file and divide configuration information into editable and non-modifiable items,meanwhile,impose a limit of type,value range and regular expression to the modifiable item to avert manmade error.Repetitive work of configuration file modifications will be realized by program,new configuration files will be generated automatically based on user modifications,and XML Schema checks will be applied to updated configuration file.The system visualizes the connetions among network decices,and the display of interface traffic and date rate will quantitatively show the network delay.This system innovates the network configuration modification by combining it with visualization.Operator can relocate station coordinate position,add or delete or modify connection by manipulating visiual chart.Finally,the thesis conducted functional testing and client-server performance testing of the system.Testing shows that the consumption of resources such as CPU and memory is reasonable,and functional realization meets expected requirements.This thesis designs and realizes a network management system based on B/S structure with WBM mode,delivering easy,convenient and efficient network management services.
