Abstract
A bandwidth allocating control apparatus for use in an optical communication base station has its reception bandwidth divided into a bandwidth for short distance and a bandwidth for long distance. A residual bandwidth calculator calculates a residual bandwidth remaining unallocated in the bandwidth for short distance after having allocated the reception bandwidth to short-distance subscriber terminal units. A middle-distance subscriber terminal classifier uses a middle-distance boundary calculation model representing the relationship between the residual bandwidth and a communication distance from the base station to the subscriber terminal units to further classify long-distance subscriber terminal units into a middle-distance subscriber terminal unit and a long-distance subscriber terminal unit. A middle-distance bandwidth allocator further allocates the residual bandwidth to the middle-distance subscriber terminal unit in addition to a predetermined bandwidth allocated thereto.
