摘要:Internet plays a vital role in our communications infrastructure, due to slow convergence of routing protocols after network failure become a growing problem. To guarantee fast recovery from link and node failure in networks, we propose a new recovery scheme called Multiple Routing Configuration (MRC). Our proposed scheme guarantees recovery in all single failure states, using a mechanism to handle both link and node failures without knowing the actual cause of the failure. MRC is strictly connectionless, and assumes only hop-by-hop forwarding from source to destination. MRC is based on maintaining additional routing information in the routers, and allows packet forwarding to carry on an alternative output link immediately after the detection of a failure. In this paper we present MRC, and examine its performance with respect to load distribution after a failure. We also present how an estimate of the traffic demands in the network can be used to improve the distribution of the recovered traffic, and thus reduce the chances of congestion in the network
