Abstract

High speed SONET rings are widely used as network infrastructure. In WDM/SONET rings, the SONET add/drop multiplexers (SADMs) can significantly increase the overall system cost. By traffic grooming, the number of SADMs as well as the number of wavelengths required can be reduced dramatically. Generally, traffic grooming includes two parts: circuit construction and circuit grooming. Efficient circuit construction will help minimize not only the number of wavelengths but also the number of SADMs. In this paper, we focus on developing improved approaches for circuit construction under static traffic patterns, using hill climber and simulated annealing. Our algorithms show good results compared to previous work.
