摘要：A bandwidth control method is disclosed that allows management on thenetwork manager side of bandwidths to be reserved. Between each of subscriber nodes,maximum bandwidths are set for each node pair in which one subscriber node is taken as
the source and the other is taken as the destination; and for the data transfer from asource subscriber node to a destination subscriber node, for each of links from thesource subscriber node to a trunk node, links between trunk nodes, and links from atrunk node to the destination subscriber node, bandwidths are set to correspond to thesum of maximum bandwidths of subscriber node pairs that carry out data transfer overthese links. For data transfer from trunk nodes to other trunk nodes or to thedestination subscriber node, virtual channels are organized by route and made virtualchannel groups, and bandwidths are reserved based on the virtual channel groups.
