A multi-processor / computer systems are connected by varieties of interconnection networks. To enable any nonfaultycomponent (Node / Link ) to communicate with any other non-faulty component in an injuredinterconnection network, the information on component failure is to be made available to non-faulty components,so as to route messages around the faulty components. In this paper we have reviewed to adaptive routingschemes proposed by Dally and Aloki , Glass and Ni ,and also the implementation details of reliable router.Moreover , it is proved that these schemes of routing messages via shortest paths with high probability and theexpected length of routing path is very close to that of shortest path.
