In recent years the Internet has been transformed from a special purpose network to a ubiquitous platform for a wide range of everyday communication services. To assure fast recovery from link and node failures in IP networks, the authors present Java based recovery scheme called Multiple Routing Configurations (MRCs). This paper guarantees recovery in all single failure scenarios, using a single mechanism to handle both link and node failures and without knowing the root cause of the failure. 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.
