Wavelength Division Multiplexing in a Wavelength Division Multiplexed Static Wavelength Routing Optical Network for a Given Topology and Traffic Request The minimum number of wavelengths required for a network using routing and wavelength assignment algorithms depends on the network node number. In order to obtain the network node number corresponding to the minimum required wavelength of the network, the node number is optimized by genetic algorithm for the first time. Compared with the existing statistical methods, the genetic algorithm can effectively eliminate the randomness and blindness of the original method. The simulation results show that the genetic algorithm can find the network node number corresponding to the minimum required wavelength of the network more quickly. The number of wavelengths required for this network is closer to the theoretical minimum
