基于MPLS VPN的电力数据通信网与ASON的互联互通

电力数据通信网是服务于电力生产、管理系统等联网应用的数据承载平台。石狮电力数据通信网采用三级分层IP/MPLS技术,采用环形和星形相结合的网络拓扑结构,网络层次分别包括骨干节点、汇聚节点和接入节点。为解决接入节点单链路的不可靠问题,文章研究利用ASON开通以太网虚拟专线,建设数据通信网备份链路,实现了ASON链路上多VPN业务的传输,以及数据通信网和ASON光传输网的互联互通,提高了数据通信网的运行可靠性。

The Interconnection Between Power Data Communication Network and Automatic Switched Optical Network Based on MPLS VPN

Power data communication network is an important data bearing plattbrm for power system production and management. Shishi power data commtinication network uses the third layer IP/MPLS technology. The network is a ring and star combined topology, including backbone node, the sink node and access node. To solve the unreliable problem of the single link of accessing nodes, this paper uses ASON to construct Ethernet virtual private line as a data communication network backup link, realizes the transmission of VPN businesses through ASON, and achieves the interconnection between data communication network and ASON optical transmission network, enhances the operation reliability of data communication network.
