Multiple Routing Configurations for Fast IP Network Recovery
Multiple Routing Configurations.pptx (Size: 200.21 KB / Downloads: 11) Abstract As the Internet takes an increasingly central role in our communications infrastructure, the slow convergence of routing protocols after a network failure becomes a growing problem. To assure fast recovery from link and node failures in IP networks, we present a new recovery scheme called Multiple Routing Configurations (MRC).. It can be implemented with only minor changes to existing solutions. In this paper we present MRC, and analyze its performance with respect to scalability, backup path lengths, and load distribution after a failure. Existing System Existing work on load distribution in connectionless IGP networks has either focused on the failure free case or on finding link weights that work well both in the normal case and when the routing protocol has converged after a single link failure Many of the approaches listed provide elegant and efficient solutions to fast network recovery, however MRC and Not-via tunneling seems to be the only two covering all evaluated requirements. However, we argue that MRC offers the same functionality with a simpler and more intuitive approach, and leaves More room for optimization with respect to load balancing Proposed System Our proposed scheme 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 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 Client Module This module is used to send the data to server through routers It will provide user friendly interface to send the data to the required destination Routers module This are placed in between server and client to transfer the data. Whenever client send the data to the server it will pass through any one router. If the router is failed the data will be transferred through another router to reduce the system failure. Conclusion We have presented Multiple Routing Configurations as an approach to achieve fast recovery in IP networks. MRC is based on providing the routers with additional routing configurations, allowing them to forward packets along routes that avoid a failed component. MRC guarantees recovery from any single node or link failure in an arbitrary bi-connected network. By calculating backup configurations in advance, and operating based on locally available information only, MRC can act promptly after failure discovery |
