Abstract
The present invention provides a bandwidth control apparatus, a bandwidth control method, and a bandwidth control system for effective utilization of bandwidths resource in data transmission. The bandwidth control apparatus measures downstream effective bit rate of own access lines and notifies downstream effective bit rate information of each access line to a remote bandwidth control apparatus which communicates with the bandwidth control apparatus via a network. The bandwidth control apparatus allocates and controls upstream bandwidths of own access lines on the basis of corresponding downstream effective bit rate information of access lines notified from remote bandwidth control apparatus via the networks.
