摘　　要：为了解决网络广播风暴引起机房主机访问网站速度慢的问题,使用科来网络分析系统对网络流量、协议、数据包等进行分析,并结合ARP欺骗、ARP扫描、蠕虫、网络路由环路和物理环路的不同表征,逐一排查ARP病毒、蠕虫、网络路由环路三个可能导致广播风暴的原因,最终定位广播风暴是由网络物理环路和交换机配置错误所导致。通过修改交换机配置和网络拓扑的方式避免网络广播风暴,使机房主机访问网站速度恢复正常。To solve the problems of low website access speed which was caused by broadcast storm, the YOKLA network analysis system has been used to analyze the network flow, protocol and data packet. Three possible causes of broadcast storms which are ARP viruses, worms, network routing loop are excluded according to their different characteristics. On the basis of the above analysis, the problem of broadcast storm has been narrowed down to the physical network loops and switch configuration error.Having identified the problem, the network broadcast storm has been solved by modifying switch configuration and changing network topology. The website access speed has returned to normal.
