Abstract:
A bandwidth control method used in a case where, for example, a first communication device (OLT) allocates a bandwidth for signal transmission to each of a plurality of second communication devices (ONUs) connected to the OLT in a communication system having the OLT and the ONUs includes a sleep controlling of shifting devices among the ONUs that satisfy a predetermined condition into a power saving state, a control-target selecting of selecting control target devices among the ONUs based on a result of performing the sleep controlling, and a bandwidth determining of determining a bandwidth to be allocated to the selected control target devices.
