Reliability Analysis of Next Generation Power Communication Network Based on SDN

Abstract

To provide basic support of information communication technology for the construction of the next generation power communication network, the reliability service support mechanism of SDN controller in the power communication network deployment scheme is studied in this paper. We analyze the security protection architecture design of power communication network based on SDN, and establish a mathematical model of controller deployment that conforms to the characteristics of power communication. Then, the inter community reliability analysis and backup method is introduced to solve the controller deployment problem in SDN network by optimizing the power of the controller in the community. In the simulation process, the network virtualization and controller are designed in detail. The experimental results show that the SDN controller placement algorithm based on community clustering ensures the reliable operation of the power grid, and it can effectively reduce the service transmission delay and packet loss rate.
