Abstract:
Link and node failure recovery is critical in any production network and recover the failures in times below 50 milliseconds is desired to maintain the quality of real time application. In this paper, we propose the Multi-Topology Recovery Protocol (MTRP) that provides network protection using pre-calculate routes and a multi-topology approach. The protocol was based on the state-of-the-art recovery and protection techniques. MTRP is based on Resilient Routing Layers (RRL) algorithm, used to generate the sub-topology. The MTRP prototype was implemented and tested in a virtualized environment, providing real IP stack in an actual operating system. The tests show that the MTRP provides a quick convergence, below few milliseconds, similar to ring protection protocol for partial mesh topology. MTRP evaluation shows that it also produces recovery paths with costs (distance) almost as low as the primary ones.
