基于SDN的智能电网故障恢复策略
Fault Recovery Strategy for Smart Grid Based on SDN
摘要
Abstract
In order to solve problems of slow speed of end-to-end packet loss detection method and high packet loss rate in power communication network, this paper designs a kind of fault recovery algorithm for smart grid link based on software defined network (SND) which adopts Openflow framework of SDN to separate link control and data forwarding plane of the power communication network and rapidly realize fault detection and reporting mechanism of the power grid link.It also designs multicast recovery mechanism for the smart grid and proposes a kind of algorithm for fault recovery of the network link in three terms of link fault detection, pre-calculation on backup multicast tree and installation of rapid backup tree so as to realize minimization of overhead of control signal.It evaluates this algorithm on POX Openflow controller by using Mininet emulator.The results indicate compared with traditional end-to-end detection algorithms, time overhead of this algorithm has reduced 90% and signal overhead of the control plane has reduced 25%.In addition, when numbers of pre-installed backup multicast groups are no less than seven, superiority of this algorithm is more evident.关键词
