A Distributed Fault Management Scheme for Wavelength Routed All-Optical Networks

A Distributed Fault Management Scheme for Wavelength Routed All-Optical Networks This paper presents a distributed algorithm to determine fault avoiding routes between source-destination end-node pairs in an all-optical network.

Abstract

This paper presents a distributed algorithm to determine fault avoiding routes between source-destination end-node pairs in an all-optical network. Fault-tolerant routing for WDM routed all-optical networks has not been studied in details in the literature except for using protection switching or loopback recovery. Such schemes use predetermined protection mechanism and hence assume that the protection path is not faulty. This paper considers extensions to a dynamic routing scheme (presented earlier by these authors for fault-free networks) 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.
