Abstract :
In this paper, desirable performance of fault localization process in all-optical networks is presented by employing the recently introduced Monitoring-Trail (m-trail) (that was proved to yield better performance by establishing monitoring resources in a shape of trails). As well, a new technique for deploying m-trails on networks along with its established lightpaths to perform fault localization is introduced. Different examples are given to illustrate this novel method with a brief description on its establishment process. Using m-trails with established lightpaths to perform fault localization is a superb technique as it saves network resources; by reducing the number of the m-trails required for fault localization and hence the number of wavelengths used in the network. A generalized solution is revealed for the Vehicle Routing Problem (VRP) variant of the famous combinatorial optimization Chinese Postman Problem for the deployment of the m-trails.
