摘要
针对5G时代下电力数据网络无法满足低时延、动态化等差异性业务服务,难以根据业务需求进行灵活切片,缺乏完整端到端路径管理等问题,文章提出一种全新的端到端网络架构设计方法。该方法将以太虚拟专网(Ethernet Virtual Private Network,EVPN)、边界网关协议(Border Gateway Protocol,BGP)、段路由策略(Segment Routing Policy,SR Policy)等网络技术应用于电力5G企业私网、全业务统一数据中心网络和数据中心骨干网络(Data Center Interconnection,DCI)。文章首先介绍网络功能互联—端到端全域网络架构思想,然后按域从数据中心网络到DCI骨干网进行分域架构和技术探讨,并列举特定场景应用,最后进行全网跨域流量路径管理分析。通过该网络架构设计方法可以实现电力5G企业私网、电力数据中心以及骨干网的统一化部署和管理。
To solve the problem that current electric power data network cannot meet the low-latency and dynamic requirement of differentiated services,this paper presents a new end-to-end network architecture design method.The method uses the mature network technologies such as Ethernet virtual private network,border gateway protocol and segment routing policy to the 5G private network in power enterprises,the all-service unified data center network and the data center interconnection backbone network.Firstly,this paper introduces the idea of network function interconnection end-toend global network architecture.Then,the architecture and technology from the data center network to the data center interconnection backbone network are discussed and the specific application scenarios are listed.At last,the cross-domain traffic path management is analyzed.By using the presented method,the unified deployment and management of the 5G private network,power data center and backbone network can be realized in power enterprises.
