摘要
以铁路数据网MPLS VPN及铁路数据网路由规范为基础,结合广州局集团公司铁路数据网MPLS VPN部署的现状,研究了铁路数据网MPLS VPN的隧道,即标签转发路径(LSP)的原理、类型和建立策略。通过分析论证和网络实践,提出了LSP建立策略的优化方案,采用前缀列表等方法有效地控制全网LSP的数量,解决了因为路由器过多造成部分LSP无法建立,从而导致铁路数据网业务数据转发失败的问题。
Based on MPLS VPN and the specification on railway data network routing and combined with the current situation of the deployment of the railway data network MPLS VPN in Guangzhou Bureau Group,the principle,type and establishment strategy of the tunnel Label Switched Path(LSP)of the railway data network MPLS VPN are studied.Through analysis,demonstration and network practice,an optimization scheme of LSP’s establishment strategy of is put forward,in which the prefix list method is used to effectively control the number of LSPs in the whole network.Thus,the problem that some LSPs cannot be established and may lead to the failure of data forwarding in the railway data network due to excessive routers can be solved.
