基于SNMP协议的网管系统的研究与设计

Research and Implementation of Network Management System Based-on SNMP

介绍了SNMP的基本原理,结合管理信息系统的相关知识,运用SNMP的轮询技术及多线程技术,设计了一个基于C/S模式的网络监控系统,包括用户管理、设备发现、实时监控、信息查询等工具模块。针对企业网和园区网的管理要求,实现了一个基于SNMP协议的综合网络监控系统。能够监控网络的实时变化,实现故障精确到具体用户,并将异常及时的通过日志、短信等方式反馈给网络管理员,大大提高了网络故障定位的准确性与网络管理的性能。

This paper introduces the principle of SNMP.By combining it with the management information system and using SNMP polling technology and multi-threading technology,a kind of Network monitor system based on Client/Server Mode is presented.These tool modules are included the user management,equipment,real-time monitoring,information query and so on.According to enterprise nets and the Campus Network,a comprehensive network monitor system based on SNMP is presented.It can monitor the network＇s real-time changes,realize the failure to specific users,and timely feedback the abnormal information to the network administrator through the log,SMS,etc.The testing result shows that this kind of system greatly improves the accuracy of network fault location and the performance of network management.
