Abstract
Virtual queue-based marking schemes have been recently proposed for Active Queue Management (AQM) in Internet routers. In an effort to improve performance of congested gateways, a new Active Queue Management (AQMNEW) algorithm was developed by feeding virtual queue size to the RED algorithm. The objective of the new algorithm is to improve overall performance by keeping link utilization high, link utilization stable, queuing delay low and consecutive packet drop rate low. This paper shows the objective is met by comparing AQMNEW with six other well known AQM methods. To provide fair comparisons, the AQM parameters are fine-tuned by exploring many different parameter settings. The simulation results conclude that AQMNEW improves overall performance by 8 to 25%.
