Paper Abstract

IP/DWDM optical Internet is considered to be a promising candidate for Next Generation Internet backbone. Fault-tolerant mechanisms have become critical technologies in IP/DWDM optical Internet. In this paper, based on preventive and reactive schemes, four fault-tolerant routing mechanisms in IP/DWDM optical Internet are proposed to deal with the problem of routing and wavelength assignment with dynamic single/multiple point failures under dynamic traffic demands, such as link/node/channel failures. The proposed mechanisms take load balancing into account, and a heuristic wavelength assignment algorithm is introduced to reduce the end-to-end delay. Simulation results have shown that the proposed fault-tolerant routing mechanisms are both feasible and effective.
