Bandwidth control apparatus, bandwidth control method, and bandwidth control system
First Claim
1. A bandwidth control system constituted by a plurality of bandwidth control apparatuses, each concentrating a plurality of access lines into a multiplexed line connecting to a network and communicating with one another via the network by controlling bandwidths of the respective access lines accommodated in each of the bandwidth control apparatuses, the bandwidth control system comprising:
- a first bandwidth control apparatus which collects bandwidth states of the respective access lines accommodated in the first bandwidth control apparatus and notifies, via the network, other bandwidth control apparatuses, which are communicating with the first bandwidth control apparatus, of the bandwidth states of the respective access lines collected; and
a second bandwidth control apparatus which receives the bandwidth states notified by the first bandwidth control apparatus, allocates bandwidths of the respective access lines accommodated in the second bandwidth control apparatus on the basis of the bandwidth states received, and controls the bandwidths of the respective access lines of the second bandwidth control apparatus in accordance with the allocated bandwidths.

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.
