<p>PROBLEM TO BE SOLVED: To provide a network band control method which enables data transmission, allotting fewer bands to the node requiring bands, if fewer bands than requested bands are usable. SOLUTION: A band control node, which controls a reception node for reception data, notifies the control node controlling the traffic of a network of the confirmation of the usable bands, and further the control node notifies a transmitting node, which controls the transmission node for transmitting data, of the confirmation of the usable band, and the control node notifies each band control node mentioned of the usable band from the band control node controlling the transmitting node and the use band decided from the information of the present use band of the network, and performs transmission and reception of the data in the decided usable band, thereby performing band control.</p> |
