Abstract:
A wavelength and bandwidth allocation method which includes in order: a wavelength allocation step of allocating each wavelength of an uplink signal to each ONU so that the sum of target bandwidths each allocated as a target to each of the ONUs to which each wavelength of the uplink signal is allocated does not exceed a bandwidth allocated to each wavelength of the uplink signal; and a bandwidth allocation step of allocating a bandwidth to each of the ONUs based on any one of a plurality of requested bandwidths accepted from each of the ONUs in each wavelength of the uplink signal so that the bandwidth actually allocated to each of the ONUs converges to the target bandwidth allocated as a target to each of the ONUs.
