A bandwidth control apparatus which can reflect current operation states or effective rates of the access lines on bandwidth distribution is realized for effective utilization of bandwidths in a subscriber data transmission system. In a plurality of bandwidth control apparatuses accommodating a plurality of access lines in a bandwidth control system, multiplexed signal lines of respective bandwidth control apparatuses are connected to one another in cascade. Each bandwidth control apparatus acquires a bandwidth state of the access lines in the own apparatus and-notifies the other apparatuses of the bandwidth state of the own apparatus having been acquired. Therefore, the bandwidth control apparatus can allocate a transmission bandwidth to be controlled in the own apparatus using a ratio of the bandwidth state occupied by the own apparatus to a total bandwidth states occupied in the bandwidth control system, and can control transmission bandwidths of the respective access lines accommodated in the own apparatus.
A bandwidth control apparatus that accommodates a plurality of access lines to which user terminals are connected and controls transmission bandwidths of the access lines, the bandwidth control apparatus comprising:
A bandwidth control system including a plurality of bandwidth control apparatuses that accommodate a plurality of access lines to which user terminals are connected, include multiplexed signal lines connected to one another in cascade, the multiplexed signal lines being formed by integrating the plurality of access lines, and control transmission bandwidths of the access lines, the bandwidth control system comprising:
A bandwidth control method for a bandwidth control apparatus that accommodates a plurality of access lines to which user terminals are connected, includes multiplexed signal lines connected to one another in cascade, the multiplexed signal lines being formed by integrating the plurality of access lines, and controls a transmission bandwidth of the access lines, the bandwidth control method comprising:
A bandwidth control method for a bandwidth control apparatus that accommodates a plurality of access lines to which user terminals are connected, includes multiplexed signal lines connected to one another in cascade, the multiplexed signal lines being formed by integrating the plurality of access lines, and controls a transmission bandwidth of the access lines, the bandwidth control method comprising:
A bandwidth allocating apparatus that allocates bandwidths of a plurality of bandwidth control apparatuses that accommodate a plurality of access lines to which user terminals are connected, include multiplexed signal lines connected to one another in cascade, the multiplexed signal lines being formed by integrating the plurality of access lines, and control transmission bandwidths of the access lines, the bandwidth allocating apparatus comprising:
