Design of a pro-active queue management

초록

In this paper, we introduce and analyze a feedback control model of TCP/AQM dynamics. Then, we propose the Pro-active Queue Management (PAQM) mechanism, which can provide proactive congestion avoidance and control using an adaptive congestion indicator and a control function for wide range of traffic environments. The PAQM stabilizes the queue length around a desired level while giving smooth and low packet loss rates independent of the traffic load level under a wide range of traffic environments. The PAQM outperforms other AQM algorithms such as Random Early Detection (RED) [1] and PI-controller [2]. ©2003 IEEE.
