摘　　要：结合虚拟路由器冗余协议及多实例生成树协议的工作原理,研究广州局承载GSM-R核心网GPRS系统的数据通信网出现的次优路由问题,提出最优路由优化方案,并予以实施,解决了因VRRP与MSTP联动产生次优路由,而影响网络正常运行的问题.Based on the working principle of Virtual Router Redundancy Protocol and Multi-Instance Generation Tree Protocol,a study was made on the suboptimal routing problem of the data communication network occurring to the GPRS system of the GSM-R core network of Guang-zhou Railway Administration.Therefore,an optimal routing scheme was proposed and implemented,which solved the problem that the normal operation of the network was affected due to the linkage of VRRP and MSTP.

关 键 词：数据通信网 虚拟路由器冗余协议 多实例生成树协议 通用分组无线业务 次优路由
