Collision avoidance wavelength assignment scheme for distributed path restoration in optical networks |
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. |
