摘要
作为信息通信技术的基础支撑部分,下一代电力通信网的建设需具备开放、泛在、智能、互动、可信等特征,实现信息通信从内部支撑电网业务为主,向"对内支撑业务,对外服务大众"并重转变。文章针对传统电力通信网在网络体系架构、业务支撑能力和运维效率等方面的问题,基于软件定义网络(Software Defined Networking,SDN)的概念与特征,分析SDN在下一代电力通信网的应用场景,并给出了SDN在数据中心互联场景下的应用部署方案。该方案通过流量工程可以灵活控制各链路数据传输速率,提升带宽利用率。
As the foundation of information communication technology, the next generation electric power communication network should be open, ubiquitous, intelligent, interactive and credible, which can not only support internal services, but also serve the public. This paper aims at the problems of traditional power communication network in the network architecture, business support capabilities and operational maintenance effi ciency, introduces the concept and characteristics of software defi ned networking（SDN） to analyze application scenarios of the next generation power communication network and presents an SDN application deployment scheme for the scenario of data center interconnection. The scheme can control the data rate of each link in a fl exible way through traffi c engineering to improve the bandwidth utilization.
