Abstract
A system, apparatus and method for dynamic intra node rerouting is described. In one embodiment of the invention, a multi-stage architecture within a network node is provided in which various module cards, including intermediary module cards, are interconnected within a chassis. A connection is established between a first module card and a second module card through an intermediate module card so that traffic may flow internally within the chassis. Failure detection and intra-node recovery are provided within the node by provisioning an intra-node compensated route around a failed module.
