Multi Topology Routing Based Failure Protection For Software Defined 5G Networks

The continuous increase in data traffic, heterogeneous access networks, and the diversity in the Quality of Service (QoS) requirements of the applications is expected to significantly increase the management complexity of 5G networks. Software Defined Networking provides an effective management architecture enabling more efficient utilization of 5G network resources. In this paper, a novel failure recovery technique, which quickly re-routes the disrupted traffic to alternate routes in case of link/node failures in the core network, is proposed to support the stringent QoS requirements of software defined 5G networks (SD5G). Experimental results show that our approach provides an efficient solution for fast failure recovery in SD5G.
