摘要
探讨了铁路数据通信网MPLS/BGP VPN体系中CE双归可能带来的问题,分析了CE双归场景下2种主要的业务接入方式,并对流量承载方式及倒换时间进行了研究;针对不同特点的业务提出差异化的接入建议,对数据通信网业务接入方式的选择具有一定的参考意义。
The issue caused by CE Dual-Homing in MPLS/BGP VPN structure of the data com- munication network for railway is explored. Two main access methods for main services in CE Dual-Homing scenario are analyzed and the traffic carrying modes and switching duration are also studied. It is proposed that differentiated access methods be adopted for services with different characteristics, offering reference for the choice of access modes of data communication network.
