铁路IP数据网优化方案探讨

Optimization Scheme of Railway IP Data Network

以京九线铁路IP数据网为例,从IP数据网存在的问题着手,探讨既有铁路IP数据网网络汇聚层和接入层的优化方案,制定IP数据网优化原则,包括系统优化原则、设备端口描述原则、路由协议选择原则和IP地址划分原则等,总结优化实施过程。

In studying the case of IP data network for Beijing - lems in IP data network and explore the optimization scheme of the IP data network for existing railway, we formulate the princ Kowloon Railway, we start fi＇om the prob- the convergence layer and access layer of es of IP data network optimization, in- cluding system optimization, device ports description, selection of routing protocol, and division of IP ad- dressing and summarize the implementation process of the optimization
