摘要
该文阐述了当前网络故障管理存在的问题,针对公安局域网出现的故障必须及时准确处理的要求,提出了基于SNMP提供的代理端自动向管理端发送故障信息的设计思想,由于TRAP包的传输是基于不可靠的UDP协议,在线路不稳定等情况下极可能出现丢包的现象,所以,设计出了以多线程运行的后台监控服务程序。这样通过双重监控,彻底解决了现在网络故障管理存在的故障漏报误报的难题。
This paper introduced the problems for network trap management firstly.To solve the requirements for police LAN trap must be timely and accurately processed,the thinking for trap information was sent to the management by the agent automatically based on SNMP was proposed,Because the TRAP packet transmission was based on unreliable UDP protocol,it was likely to drop packages in unsta ble line.Therefore,the background monitoring service program of using multiple threads was designed.Through the double monitoring,the problems for missing and false alarms were completely solved.
