ENERGY-EFFICIENT DESIGN FOR IP OVER WDM NETWORKS WITH CLOCK FREQUENCY ADAPTIVE ROUTER CARDS

摘要：

　　Because a router card consumes less energy at a lower clock frequency,we can minimize the energy consumption of an IP over WDM network by adaptively adjusting the clock frequencies of a router card according to its actual carried traffic demand.We develop a mixed integer linear programming(MILP)model and an efficient heuristic algorithm to adjust the clock frequency of a router card in different time slots.Results show that the clock frequency adaptation strategy can significantly reduce the energy consumption of an IP over WDM network compared to the non-adaptive case,and the heuristic algorithm is efficient to perform as close as the MILP model.
