Monitoring-Tree: an Innovative Technique for Failure Localization in WDM Translucent Networks

Résumé

Because of the very high optical fiber's capacity, prompt and unambiguous fiber cut detection is mandatory to guarantee carriers' network survivability. In this matter, the monitoring-cycle and the monitoring-trail mechanisms have been proposed in the recent literature. In this paper, we propose the innovative concept of monitoring-tree that enables to reduce considerably the monitoring cost while keeping unambiguous single fiber cut detection and localization. We propose an ILP formulation aiming at mapping a monitoring-tree onto a mesh topology. Applied to real networks, we show that our approach outperforms its counterparts.
