Traffic grooming for internetworking using optical networks

Traffic grooming on logical topologies is an important problem in internetworking. This paper explores the use of regular topologies as possible models for the logical topology of WDM wavelength routed networks. After defining the problem, a genetic algorithm approach to designing logical topologies has been proposed. The approach has been compared to the optimal design which can be done only for very small networks. The experiments reported here indicate that using the new approach is quite viable and works reasonably well for networks of practical size.
