协议分析法在局域网故障分析与维护中的应用

On the application of the protocol analysis method in LAN fault analysis and maintenance

针对故障维护在局域网安全中的重要性,提出了一种能准确、快速定位并排除局域网故障的方法——协议分析法.通过该方法从网络整体性能、计算机病毒、DoS、MAC泛洪攻击、网络带宽滥用、异常广播等方面分析局域网的故障并提出了相应的维护措施,实践证明,该方法的应用提高了局域网的稳定性和安全性.

Aiming at the importance of the fault maintenance in LAN security, the paper put forward a kind of accurate, rapid positioning LAN fault method named protocol analysis method. This paper adopts the method from the aspects of the whole network performance, computer virus, denial of service, MAC flood attacks, network bandwidth abuse, abnormal radio to analyze the LAN fault, and put forward the corresponding solving measures, and has achieved good maintenance effect, which improved the stability and security of the local area network.
