ABSTRACT:
A band allocation method in a communication system in which nodes and a managing apparatus are coupled via a network and each node requests a transfer band with respect to the managing apparatus is provided. The method includes sending tolerable values of a transfer rate and a compression rate sent from each node to the managing apparatus at a time of a resetting, and a transfer rate and a compression rate that are to be actually used are sent from each node to the managing apparatus when making a request for a transfer band after the resetting. The includes detecting a node that cannot secure the transfer band and calculates a lacking bandwidth with respect to the request for the transfer band, and detects a node that can reduce a transfer band thereof and specifies a transfer rate and a compression rate with respect to the node that can reduce the transfer band thereof. The transfer band, the transfer rate and the compression rate are specified as requested by the request for the transfer band with respect to the node that cannot secure the transfer band.
