Overview:

This paper studies a traffic grooming in Wavelength-Division Multiplexing (WDM) mesh networks for the SONET/SDH streams requested between node pairs. The traffic could be groomed at the access node before converting to an optical signal carried in the All-Optical network. The paper designs a virtual topology with a given physical topology to satisfy multiple objectives and constraints. The grooming problem of a static demand is considered as an optimization problem. The algorithms found in the literatures focus on a single objective either to maximize the performance or to minimize the cost. The paper proposes a Multi-Objective Evolutionary Algorithm to solve a grooming problem that optimizes multiple objectives all together at the same time.
