Abstract:

In order to minimize the number of electric equipment and wavelength in optical networks, a genetic algorithm of arranging the order of multicast traffics was proposed and therefore the traffics were groomed according to the orders. Two grooming algorithms based on non-restricted multi-hop provisioning were also proposed. The minimum value of required electric equipments of theory was calculated and compared with the result of genetic algorithm. Simulations show that the value of genetic algorithm is close to that of theory and genetic algorithm is applicable for traffic grooming under different conditions.

Key words: multicast, grooming, optical network, genetic algorithm
