ABSTRACT:
An inter-network relay unit is provided that is capable of simultaneously achieving guaranteed minimum bandwidth and priority control (including relay priority, discard priority, delay priority, etc.). A rate controller outputs relatively high priority packets from priority queues as guaranteed traffic based on guaranteed bandwidth for each link. Relatively low priority packets left in the priority queues are marked for preferential discard and output as best-effort traffic by an aging timer. When an output port is congested, an output queue portion discards only the marked packets. Thus, traffic having a plurality of relay priorities can use the guaranteed minimum bandwidth effectively and the guaranteed minimum bandwidth can be secured, irrespective of change in traffic volume for each relay priority level.
