Abstract
In wavelength-routed optical networks, the recovery ratio of interrupted connections after failures is mainly affected by adjacent-node resource reservation collisions in a distributed path restoration. This paper proposes a novel collision avoidance wavelength assignment (CA-WA) mechanism to make adjacent nodes select different wavelength assignment schemes and therefore different recovery wavelengths for the recovery routes. Simulation results show that in both single- and double-fiber failure scenarios the proposed wavelength assignment mechanism significantly reduces reservation contentions and achieves a higher recovery ratio, especially when the network load is high.
