Abstract
A method is provided for handling packets at a queuing point in a packet-based communication system that handles the packets, when each of the packets is assigned one of a plurality of service priorities. At least one discard threshold is assigned to each of the service priorities, and when one of the packets is delivered to the queuing point, a count of the total number of packets or bytes stored in a queue at the queuing point is maintained. That count is compared with a selected discard threshold associated with the service priority assigned to the packet delivered to the queuing point, and that packet is selectively discarded if the count reaches the selected discard threshold. Packets having different service priorities may be stored in the queue.
