In this paper, we propose a new heuristic algorithm, protection based on survivable integrated auxiliary graph (PSIAG), to tolerate the single-link failure in waveband switching optical networks. The survivable integrated auxiliary graph (SIAG) contains single virtual topology layer and multiple waveband-plane layers, and it can well solve the routing and waveband assignment. In PSIAG, we can well use the waveband sub-path grouping scheme based on SIAG to save the switching ports. Simulation results show that PSIAG performs better than previous algorithm.
