浙江省电力公司信息网组播部署

浙江省电力公司信息网由骨干网、城域网与接入网组成,经多年建设已具备一定规模。为更好支持视频等新业务的开展,浙江省电力公司将按照现有信息网多域设计进行相应组播部署,域内运行PIM SM协议,域间通过MBGP传播组播拓扑信息、通过MSDP传播组播源信息,从而实现相同数据流的客户端通过加入相同的组而共享同一数据流,不仅节省了网络带宽,还减轻了服务器的负载。

Muiticast Deployment for Zhejiang Electric Power Corporation's Network

After years of construction, network of Zhejiang Electric Power Corporation has a certain scale, which consists of backbone network, metropolitan area network and access network. In order to greatly support the development of new services such as video service, multicast deployment is imposed on corporation＇s network according to the idea of multiple domain design, in which intra-domain runs PIM SM protocol and inter-domain runs MBGP and MSDP protocol to broadcast multicast topology data and multieast source data respectively. Because clients can share the same data stream by joining the same group, it is helpful to save network bandwidth and reduce servers＇ workload.
