针对西气东输江都－如东线频繁出现网络故障的情况，基于江都－如东线现有网络架构，分析了网络系统存在的不足，对网络架构进行了优化，重新划分了局域网，处理了网络环网，禁用了路由器的多余广播，进行了风暴控制，优化了 ESD 系统参数，提出了在江都－如东线进行网络架构优化的方案。通过对思科交换机、思科路由器、SIXNET 交换机和 ESD 系统的配置进行修改，以及为期1年的试运行，实现了网络故障零发生的目标，提高了网络通讯的质量，保证了系统的可靠性和安全性。

With respect to frequent network faults occurring on the Jiangdu-Rudong pipeline of the West-East gas transmission project,on the basis of the existing network architecture of the pipeline,this paper analyzes inadequacies of the network system,optimizes the network architecture,divides the LAN again,regulates the network loops,prohibits superfluous broadcasting of the router,conducts storm control,optimizes ESD system parameters,and proposes an optimization scheme for the network architecture of the pipeline. Through modification of Cisco switch,Cisco router,SIXNET switch and ESD system configuration,as well as one year trial operation, we have achieved the goal of zero network failure,improved the quality of network communication and guaranteed system reliability and safety.
