Achieving Fast BGP Reroute With Traffic Engineering Using Multiple Routing Planes

In today's BGP routing architecture, traffic delivery is in general based on single path selection paradigms. The lack of path diversity hinders the support for resilience, traffic engineering and QoS provisioning across the Internet. Some recently proposed multi-plane extensions to BGP offer a promising mechanism to enable diverse inter-domain routes towards destination prefixes. Based on these enhanced BGP protocols, the authors propose in this paper a novel technique to enable controlled fast egress router switching for handling network failures.
