Design of load-adaptive queue management for internet congestion control

초록

In this paper, we propose the Proportional-Integral-Derivative (PID)-controller, which can provide proactive congestion avoidance and control using an adaptive congestion indicator and control function. The goals of PID-controller are to control congestion proactively, to stabilize the queue length around a desired level and to give smooth and low packet loss rates. An extensive simulation study suggests that PID-controller outperforms other active queue management (AQM) algorithms such as Random Early Detection (RED) [1] and Proportional-Integral (PI) controller [2] in terms of the queue length dynamics and the packet loss rates. © Springer-Verlag Berlin Heidelberg 2003.
