With the rapid development of Internet, the network traffic explosively grows with the emergence of new network business.The existing electric power communication networks still have the traditional architecture that is the closed system highly integrated with devices and software, which cannot satisfy the development requirements of smart grids.In this paper, we combine the electric power communication networks with Software Defined Network (SDN) that includes the NOX controller in the control plane, switches in the data forwarding plane, and the OpenFlow protocol supporting the communication between controller and switches.Especially for the scenario of the network expansion, the NOX controller dynamically configures end-to-end paths, and we then demonstrate the feasibility of our design by checking the flow tables in switches.Additionally, the CPU utilization of the NOX controller and end-to-end delay are both analyzed in our experimental platform.
