Abstract

This paper proposes two protection algorithms, Segment-Based Protection (SBP) and Path-Based Protection (PBP), in fault-tolerant multi-domain optical networks to support waveband grouping with the layered auxiliary graph concept. To the best of our knowledge, this paper is the first study to achieve the fault-tolerance and waveband switching in multi-domain optical networks. Simulation results show that PBP has better performances than SBP.
