摘要
数据通信网边缘路由器(PE)与用户边缘路由器(CE)设备采用"口"字型对接的静态路由。由于静态路由易产生非对称路由,当铁路数据通信网组网方式发生改变,或设备商在CE侧进行业务主备切换时,可能导致业务中断。为此提出网络优化建议,以改善了网络安全性、冗余性和健壮性,确保业务安全可靠运行。
The edge router(PE)of the data communication network and the user edge router(CE)device are docked with hollow square type connector and the PE device and CE device are routed statically.Since static routing is prone to generate an asymmetric routing,it may cause service disruption when the networking mode of railway data communication network changes or the operator conduct main/backup switching of services on the CE side.To this end,the proposal of network optimization is presented for improving the security,redundancy and robustness of the network,and ensuring the safe and reliable operation of the services.
