Abstract: Using the layered graph, a static traffic grooming scheme based on predatory search algorithm (PSA) and gaming was proposed for IP over WDM optical Internet, in order that the comprehensive user traffic request delay satisfaction degree is maximized and the network relative cost is minimized under the constraints of the user traffic bandwidth and delay request In the proposed scheme, the transition between the local and the global search is realized by adjusting the restriction level of search space, and then the optimal traffic grooming scheme is found. It was simulated over actual network topologies and its performance was compared with certain existing traffic grooming scheme. Simulation results show that it has better performance.
