Abstract
Disclosed herein is a method for deadlock avoidance in a network comprising partitioning in a module, a set of virtual lanes into deadlock avoidance virtual channels; where each deadlock avoidance virtual channel comprises a plurality of virtual lanes; assigning each incoming packet at the module to one of the deadlock avoidance virtual channels, and within the deadlock avoidance virtual channel to a virtual lane whose relative index corresponds to an absolute index of the virtual lane the packet would have been assigned to if the network was not provisioned with deadlock avoidance virtual channels; and transitioning each packet as it traverses the module from one deadlock avoidance virtual channel to another deadlock avoidance virtual channel when a deadlock avoidance policy so demands it.
