Summary:The deployment of WDM networks enables a fiber to provide a huge bandwidth several factors above the current levels. Considering the enormous amount of information carried by a fiber in WDM networks, restoring traffic disrupted by a fiber/cable cut is even more critical than the SONET network. This paper provides a summary of results of our spare capacity planning and distributed restoration schemes on two networks. The restoration scheme is a distributed path restoration algorithm. The spare capacity planning was efficient and the distributed restoration algorithm restored 100% within a second for single link failures. The results show that sub-second distributed restoration is possible in WDM networks.
