Abstract
A terminal with a shaper comprising an ABR bandwidth calculator for calculating a shaping bandwidth from congestion notification information in each received RM cell and a bandwidth allocator for calculating bandwidths allocated between respective connections with the bandwidths given priorities, wherein cells are transmitted with one small in value, of the result of calculation by the ABR bandwidth calculator and the result of calculation by the bandwidth allocator as a shaping bandwidth. With respect to connections subjected to a limitation of each shaping bandwidth by the congestion notification information, the priority for bandwidth allocation is lowered so that the bandwidths unavailable to the connections are deallocated to other connections.
