Abstract
There is provided an optical line terminal that dynamically allocates communication bandwidth to a plurality of optical network units in an optical communication network, the optical line terminal including a minimum bandwidth allocation unit calculating allocation bandwidth of the plurality of optical network units based on bandwidth request information notified by the plurality of optical network units, a comparison unit comparing an allocation cycle given as the sum total of allocation bandwidth allocated to the plurality of optical network units respectively with a predetermined threshold value, a best-effort bandwidth allocation unit calculating remaining bandwidth as best-effort bandwidth of the plurality of optical network units when the allocation cycle is less than the threshold value, and a bandwidth allocation unit allocating communication bandwidth of the plurality of optical network units based on the allocation bandwidth and the best-effort bandwidth.
