Abstract:
A bandwidth allocation system of a virtual path for allocating bandwidths for a plurality of virtual paths in a communication network of asynchronous transfer mode, wherein a node in said asynchronous transfer mode network comprises:bandwidth monitor means for calculating a bandwidth used for a virtual path by measuring a cell amount entered into each virtual path; cell storing means for storing an input cell for each of said plurality of virtual paths; bandwidth allocation control means for determining a bandwidth allocation ratio for output bandwidths in accordance with a used bandwidth ratio obtained by reference to each bandwidth used for each of said plurality of virtual paths from said bandwidth monitor means in accordance with a change of the Queue length in the cell stored within said cell storing means; and output bandwidth control means for controlling output of said respective cell storing means, in accordance with the bandwidth allocation ratio determined by said bandwidth allocation control means.
