Paper Abstract

This paper presents a routing and wavelength assignment for survivability (RWAS) algorithm in optical networks. The attentions of most previous RWA algorithms focus on traffic balance, blocking performance, and network resource utilization, which are key performances of optical networks. However, with the development of DWDM systems and the increase of traffics in optical network, services survivability and network survivability must be paid much more attentions to. RWAS considers services survivability while routing and assigning wavelength(s) for a set of connections, which perhaps has not better resources utilization and blocking performances, but assures that as many service connections as possible can be restored in the current network in the case of any single link failure.
