Abstract
Cells are discarded in conformity with the order of priority when congestion occurs by discarding cells of a traffic class without any special contract for a transfer rate at the time of setting up a connection. A node stores priority information concerning cell discard corresponding to a connection identifier and controls the cell discard in accordance with the discard condition determined by the accumulated number of cells for each connection in the node and cell priority.
