Abstract

An approach to design large multi-layer networks is herein proposed. Transparent lightpaths are primarily put in place to deal with demands with high values of traffic-distance product. The remaining traffic demands are then groomed and routed over both physical and virtual topologies. Deactivation of underutilized wavelengths along with configuration random perturbations are used to bring down the number of transceivers. Results are com-pared with exact Integer Linear Programming (ILP) models. The proposed heuristic not only approaches exact ILP results, but it also outperforms the relaxed ILP models that are focused on mini-mizing the link using the larger number of transceivers.
