Abstract

Fault-tolerant routing for WDM routed all-optical networks has not been studied in details in the literature except for single fault occurrence in a simple topology, like a ring. Conventional routing schemes, being static in nature, are difficult to be modified to handle faults as fault occurrences need dynamic rerouting. In this paper, we present a fault-tolerant routing scheme for WDM routed all- optical networks. This paper considers modifications to a dynamic routing scheme to handle rerouting in case of fault occurrence. The performance degradations of the network because of fault occurrence are then studied in terms of blocking probability and set-up time through simulations.
