  • A genetic algorithm of optimizing the order of arranging multicast services in optical network is proposed. Then the multicast trees are constructed and wavelengths are chosen by the optimized order to minimize the required number of wavelengths and multicast links in optical network. Three routing algorithms and the ameliorative effect of wavelength converters on resource optimization are compared. Simulations in NSFNet show that in sparse splitting network, when the number of multicast capable nodes is half of the number of total nodes, the resource optimization has been acceptable.
