An Intelligent Traffic Grooming Scheme for IP over WDM Optical Internet

In this paper, an intelligent static traffic grooming scheme based on predatory search algorithm (PSA) and gaming is proposed in IP over WDM (Wavelength Division Multiplexing) optical Internet. Based on the layered graph, the proposed scheme tries to maximize the comprehensive user traffic request delay satisfaction degree and minimize the network relative cost, and then the optimal traffic grooming scheme is found through the transition between the local and the global search realized by adjusting the restriction level of search area. It is simulated over actual network topologies. Simulation results show that it is both feasible and effective with better performance than certain existing traffic grooming scheme.
