Abstract A path based Integer Linear Programming (ILP) method is proposed to optimize the network energy consumption under the bandwidth constrained transparent IP over WDM network model. Compared with the link based ILP method, this method can provide more lightpath combinations in the optical layer. The simulation results show that the path based ILP method can select the better lightpath combinations than the link based ILP method, and achieve lower network energy consumption.
