An Evolutionary Programming Approach for Traffic Grooming in WDM Rings
SDH self-healing rings are the moat popular transport architecture deployed in telecommunication networks. WDM technology has been successfully applied to increase the capacity of existing SDH/SONET rings. As wavelengths are no longer such precious resources, SDH odd-drop multiplexers (ADMs) become the dominant cost factor. Traffic grooming studies how to intelligently arranging the placement of ADMs on wavelengths to reduce ADM. Lots of research has been done in this area and a number of knowledge-specific heuristics have been proposed for certain network architectures and traffic patterns.In this paper, we propose an evolutionary programming based approach for traffic grooming. Numerical results obtained show that our EP approach achieves better results in most cases than greedy heuristics. Sometimes it can even reach lower bounds. Because EP does not rely as much on specific knowledge of traffic grooming as other heuristics, it holds a promising prospect to be applied to more sophisticated traffic grooming problems.
