ABSTRACT:
A bandwidth allocation system of a virtual path in an asynchronous transfer mode includes a virtual path setting unit, a bandwidth allocating unit, an attribute assigning unit, a group bandwidth allocating unit, and a cell output unit. The virtual path setting unit sets a plurality of virtual paths in a repeating line of an asynchronous transfer mode communication scheme, each of the virtual paths being a direct link which logically determines a route and a bandwidth in an asynchronous transfer mode switching network. The bandwidth allocating unit allocates a bandwidth for each virtual path. The attribute assigning unit assigns attributes classified in accordance with a communication quality to a plurality of virtual path groups obtained by bundling the virtual paths. The group bandwidth allocating unit proportionally distributes bandwidths to the virtual path groups in accordance with a sum total of the bandwidths allocated to the virtual paths constituting the virtual path groups and sets a virtual path network. The cell output unit outputs a cell of terminal information to the repeating line in accordance with the attributes assigned to the virtual path groups.
