An improved active queue management algorithm based on queue length and traffic rate factor

Abstract

Serious queue jitter and sluggish response to dynamic network traffic are problems in existing AQM algorithms.Our study has focused on the judging mechanism of link congestion and proposed an algorithm combining the queue factor and load factor.The algorithm can make adaptive adjustment to the loss probability function with instantaneous queue length and provide better performance in control.It is verified by NS simulations to enhance the responsiveness of queue and make high link utilization.It also improves the adaptability and robustness of active queue management. © 2011 Springer-Verlag Berlin Heidelberg.
