Abstract :It has been observed that failures of routers and its connecting links in Ethernet LAN cannot be completely avoided even in well maintained networks. Due to failure, many events occur in the affected network, such as topological changes, loss of packets, recovery of the routing table etc. There are various causes of network failure such as the failure of a router, failure of one of its connecting link or when a router is deliberately withdrawn etc. Under such failed conditions, a quick convergence scheme is extremely essential for the packet transmission of the network. Route recalculation and rebuilding of routing tables, for the recovery of network failure, is the main approach used by today’s IP router. However, route recalculation and routing tables building up are time consuming. Mean while, a large number of packets may be dropped due to failure of link. In this paper, we have proposed an alternate efficient IP rerouting scheme based on Steady State Routing Table (SSRT), using binary Router (having 2 ports only), which automatically switches to the pre-calculated backup routes following a network failure. Consequently, the Ethernet LAN can recover immediately as recalculation of routes or rebuilding of routing tables are not needed.
