一种SDN中基于SR的多故障恢复与规避机制
A Multi-fault Recovery and Avoidance Mechanism of Software-Defined Network Based on Segment Routing
摘要
Abstract
Considering the multi-fault problem in Software-Defined Network (SDN),a segment routing based multi-fault recovery and re-breakdown avoidance mechanism is proposed.In order to achieve fast recovery of failures,a linkageloop backup system aiming at fast recovery for multi-fault problem is proposed with SR technology in dataplane.To avoid second failure caused by breakdown in some links due to the overload problem in failure recovery,an optimal traffic smoothing algorithm is proposed to balance the traffic among links where the traffic goes beyond the threshold.Experiments result show that compared with the schemes OAM-Based and Fast Failover,the proposed scheme improves the success rate of failure recovery by 6.7％ and 8.5％,and the cost in controller is only 9％ of the traditional OpenFlow scheme.At the same time,the proposed scheme also deals with the overload problem in failure recovery,which protects the network in failure avoidance scope.关键词
