摘　　要：针对铁路数据通信网分区域组网的现状,提出一种跨域铁路数据网综合组网设计方案,并在eNSP环境中进行仿真。方案在多AS区域、多协议作用场景中,实现了域内路由、域间路由、路由控制优化、跨域私网互通等高级路由控制。有效解决综合数据网设计、设备管理配置、结果分析测试、网络故障诊断等网络工程技术问题。方案可为设备维护人员提供技术帮助,为后续铁路数据网的线网建设提供有效依据和参考。In view of the current situation of railway data communication network in different regions,this paper proposes a design scheme of cross region railway data network integrated networking,and itis simulated in the environment of eNSP.In the scenarios of multiple as regions and multiple protocol interconnection,the scheme realizes advanced routing control such as internal domain routing,inter domain routing,routing control optimization,cross domain private network intercommunication,etc.It can effectively solve practical network engineering problems such as integrated data network design,equipment management and configuration,result analysis and test,network fault diagnosis,etc.This scheme can provide technical help for the engineers who maintain the real equipment of data network,and also provide effective basis and reference for the subsequent construction of the railway data network in the future.
