On a router-port basis, our previous study [1] found that lightpath bypass strategy can significantly save power consumption over the lightpath non-bypass strategy. However, in real network systems, router ports are organized by network line cards or modules; on each line card there are multiple router ports. In this paper, we evaluate the energy consumption of an IP over WDM network in the context of modularized router ports. We develop mixed integer linear programming (MILP) model for power… CONTINUE READING
