Abstract
In accordance with methods and systems consistent with the present invention, an improved deadlock-free routing system is provided to a family of network topologies where both the configuration of the networks and the routings are designed to optimize performance. In this system, each network utilizes static routing tables that perform deadlock-free routing in an optimized manner to reduce the amount of communication overhead when routing traffic. Specifically, the routings in accordance with methods and systems consistent with the present invention require no more than two hops for networks up to a size of 16 nodes. As a result, the deadlock-free routing provided in accordance with methods and systems consistent with the present invention incurs less communications overhead than some conventional systems while still avoiding deadlock.
