Abstract

IP over DWDM optical Internet is one of the main networking techniques for NGI (Next Generation Internet), and how to improve its fault-tolerance capability and QoS (Quality of Service) becomes critical. Fault-tolerant QoS routing is one of the effective solutions. In this paper, a reactive fault-tolerant integrated QoS unicast routing scheme is proposed based on heuristic A algorithm to deal with the case of single-link/single-node failure. Its objective is to make the best balance among delay, load and the cost of wavelength conversion, trying to improve the wavelength utilization and failure restoring rate. Simulation results have shown that the proposed scheme is both feasible and effective.
