Paper Abstract

Based on the layered-graph, this paper proposed an integrated routing algorithm named CIR (i.e., Cost-based Integrated Routing) for IP/GMPLS over WDM networks. Assuming a peer model in GMPLS-Based optical networks, we take into account the network topology and resource usage information on both IP and WDM layers. Focusing on the problems of bottleneck and bandwidth fragment, we combine a cost function of lightpath in our algorithm as the main implement to solve them. The optimized routing scheme is determined by the minimum cost value. In the simulation, we compare CIR with two representative routing algorithms (i.e., HIRA [2] and MinLP [3]) in IP over WDM networks in terms of blocking probability (BP) and wavelength utilization. The result shows that CIR can optimize the network resource utilization to accept more connection requests and reduce traffic BP efficiently.
