Abstract
In accordance with methods and systems consistent with the present invention, an improved failure recovery system is provided that, upon detecting a failure, generates new routings for the network which (1) avoid the failure and (2) avoid deadlock. In this manner, after a failure is detected, the network remains as operational as possible while still avoiding deadlock. Thus, by using the improved failure recovery system, a network failure has a much less severe impact on the network than in conventional systems.
