Fast IP Network Recovery Using MRC
Internet takes vital role in the communications infrastructure, due to slow convergence of routing protocols after network failure become a budding problem. To assure fast recovery scheme from link and node failure in networks, the authors present a new recovery scheme called Multiple Routing Configuration (MRC). Their anticipated scheme guarantees recovery in all single failure scenarios, using a mechanism to handle both link and node failures, and without knowing the root cause of the failure. MRC is strictly connectionless, and assumes only destination based hop-by-hop forwarding. MRC is based on keeping additional routing information in the routers, and allows packet forwarding to continue on an alternative output link immediately after the detection of a failure.
