The design of SDN technology application in power communication access network

Introducing the concept of SDN technology, this paper proposed to establish, combining with the current business of the power communication access network in Liaoning Province, a unified SDN-based control platform which defines the OpenFlow as the standard communication protocol between the control layer and forwarding devices. According to the network programmability, this paper realizes a balanced planning of the limited resources. In Liaoning Province power communication access network, we build a multi-level flow table in OpenFlow forwarding model to enhancing the capability of Intelligent Edge forwarding in control layer, the efficient carrying capacity of backbone network, and network openness and interoperability, and to realize the unified management and control of power communication equipments.
