A multi-level active queue management scheme was described that combined packet classification and random early detection (RED) capabilities to provide differentiated performance characteristics for different classes of service. This scheme used a simple control-theoretic algorithm to randomly discard packets with a load-dependent probability when a buffer in a router got congested. The algorithm controlled the average queue size close to the control target and allowed arriving bursts to be accommodated without dropping excessive packets.
