In this letter, we propose a new routing algorithm based on integrated auxiliary graph (RA-IAG) to reduce switching ports in waveband switching optical networks. The IAG is compared of a single virtual topology layer (VTL) and multiple waveband-plane layers (WPLs). For each demand, RA-IAG first computes a single-hop or multi-hop route on VTL. If the route cannot be found on VTL, RA-IAG then computes a hybrid multi-hop route by jointing VTL and WPLs. Simulation results show that, compared with previous algorithm, RA-IAG can obtain better performance.
