<p>A method and system is described for the restoration of communications in a communication network upon the detection of a perceived fault. The system does not know whether the actual fault is on the link or the node connected to the link. The system needs only to perceive the actual fault. Upon fault detection, the system reroutes communications affected by the fault onto predefined restoration paths using a set of switches called cross-connects. Each restoration path is restricted to an island which is a prescribed sub-network of nodes and links surrounding the fault.</p> |
