AN ADAPTIVE MULTI-OBJECT ROUTING ALGORITHM IN WDM OPTICAL NETWORKS

摘要：

Different dynamic routing and wavelength assignment algorithms for WDM optical networks are described in this paper. A new dynamic algorithm based on the layered graph model and called Multi-object Optimal Algorithm (MOA) is proposed. A distinguished feature of MOA algorithm is that it employs more accurate network information than the existing algorithms on the availability of both the number of available wavelengths and the hops of the lightpath in deciding the routing and the wavelength assignment. In this paper, the detailed information per link is analyzed and the allocation of network resources is optimized under dynamic service traffic. Simulation results show that the algorithm MOA performs much better than some proposed traditional algorithms with comparable computation time.
