A Comparative Study of Active Queue Management Algorithms for Network Performance Evaluation

Abstract

With the current advances in network activities, there appears to be wide needs for Quality of Services (QoS) and fairness among flows. As such, the links are also forced as a result in order to effectively perform in congestion control and avoidance. For this reason, active queue management algorithms were proposed in order to handle QoS issues. This study will examine the unique the performance effeteness of three AQM algorithms  namely  REM, AQV, and CoDel due to the little evidence found in literature about their performance. The performance above mentioned algorithms will be  evaluate via simulation tool (NS2) in terms of  response time, throughput and  packet loss  in  single link network . The throughput result showed that REM performed best, closely followed by CoDel and AVQ. REM has the faster response time, followed by CoDel , with AVQ performing worst overall by a significant margin. the packet loss showed AVQ, and CoDel  algorithms to do equally, and seem  REM performs very poorly. The performance result of REM, AVQ, and CoDel showed different performance results in which REM and CoDel mechanisms helped control the amount of bandwidth shared within a network.
