Abstract

This paper proposes fault detection and localization scheme to handle multiple failures in the optical network using wavelength-division multiplexing (WDM) technology. This proposed scheme is two-phased scheme containing (a) the detection of faults through monitoring devices raising alarms (fault detection) and (b) subsequently the localization of these faults (fault localization) by invoking an algorithm. The later phase will obtain a set of potential faulty nodes (links). We demonstrate the performance of the scheme on 14-node NSFNet and 28-node EuroNet. We compare our scheme with an existing algorithm [1] for locating faulty nodes (links). Our scheme outperforms the existing one.
