Abstract

A system and method for routing data, the system having a processor, an interface in communication with the processor and capable of being in communication with a second system for routing data, a memory unit in communication with the processor, the memory unit having a network routing table having a plurality of routes, the plurality of routes having a first route; and a network failure route selection logic including instructions adapted to configure the processor to determine when the first route is inoperative, transmit a first data packet to the second system for routing data when the first route is inoperative and utilize a second route selected from one of the plurality of routes, the second route being different from the first route.
