Abstract—A hybrid approach, namely, Proportional Ratebased Control (PRC), is proposed to maintain the queue length around the target level by 1) dropping the packet whose arrival rate exceeding maximum desired rate; 2) using virtual queue to control the packet whose arrival rate above minimum desired rate. We compare the performance of PRC through simulation with several well-known AQM schemes such as RED, DRED, SRED, AVQ and VRC. The study shows that the proposed scheme is more effective at stabilizing the queue size and has lower loss rate than others. Another appealing feature of the proposed scheme is that the system responds quickly and accurately to changing network conditions.

Index Terms—Active queue management, rate-based control and queue regulation.
