Abstract

We investigate WDM network performance improvement by applying routing algorithms taking into account service differentiation in terms of signal quality requirement. We consider network survivability based on dedicated and shared path protection where both working and protection paths are calculated according to our algorithm. A significant improvement is obtained compared with the conventional algorithms.
