Abstract: Different fault-tolerant routing mechanisms in IP/DWDM optical Internet are discussed. The problem of routing and wavelength assignment with dynamic single/multiple point failures in demand of dynamic traffic is dealt with, such as link/ node/channel failure. The proposed routing algorithm takes load balancing into account, and a heuristic wavelength assignment algorithm is proposed to reduce the end-to-end delay. Based on preventive and reactive schemes, four fault-tolerant mechanisms are put forward. Simulation results have shown that the proposed mechanisms are feasible and effective.
