- In a wavelength allocation method in a wavelength division multiplexing network, a 3R wavelength converter having a limited wavelength conversion range is disposed according to a wavelength conversion band of each node, at least one path set between transmitting/receiving nodes is selected, routing paths corresponding to the number of the selected at least one path set between the transmitting/receiving nodes having a request for a new optical path generation are extracted, it is determined whether there is a wavelength consecutive segment set that satisfies a maximum transmission distance for guaranteeing transmission quality of an optical signal and that includes one consecutive wavelength among the extracted routing paths, and a path using a first-fit wavelength is selected from paths of each wavelength consecutive segment and the wavelength is allocated when determining that there is a wavelength consecutive segment set.
