Lightpath protection using genetic algorithm through topology mapping in WDM optical networks

摘要

In WDM optical networks, design protection algorithms aim to maintain the connectivity between two nodes in the network following a failure by mapping a given virtual topology onto the physical topology so as to minimize the failure propagations in a network. In this article, a genetic algorithm based approach has been proposed for design protection in WDM optical networks. The proposed method has been compared with two other well-known design protection algorithms to establish its effectiveness.
