Research on the Application of Software Defined Network in Electric Power Data Communication Network

Software defined network (SDN) is a new architecture of network. The design concept of SDN is the separation of network control plane and forwarding plane and the realization of programmable control. Standford University put forward the concept of openflow in 2007, it provides standard interfaces and separates the data forwarding and routing control function of the traditional network communication equipment by the flow control method. The article makes a deep research on SDN from the aspects of technical connotation, equipment model and etc. It also makes a research on the actual demand and the existing problems of electric power data communication network of which the application of SDN in electric power data communication network is discussed.
