Özet

Real-time services in IP networks require a fast switching of disrupted traffic to alternate paths in case of link/node failures to satisfy their stringent Quality of Service requirements. Multi Topology Routing (MTR) based IP Fast Re-route (IPFRR) technologies rely on virtual topologies to seamlessly forward the IP packets during network failures by activating the proactively computed alternate routes which avoid the failed component. Multiple Routing Configurations (MRC) is a widely studied MTR based IPFRR technique which provide full protection against network failures. In this paper, a new MRC-based fast re-route technique for Software Defined Networks (SDN) is proposed. Our experimental results show that our approach considerably reduces the recovery time from network failures compared to the reactive Shortest Path First (SPF) routing.
