Abstract
AQM is an effective method to improve the performance of end-to-end congestion control. The behavior of various AQM schemes with respect to buffer capacity issues has not been studied in much detail. In this paper, we show the effect of router buffer size on AQM schemes based on queue length and present the reason: the buffer saturation will make the input and output of AQM schemes conflicting. We also propose a saturation compensator which can improve the performance of AQM schemes when routers have small buffer. At last, using PI as an example we propose PI with saturation compensator whose performance is evaluated through NS2 simulations.
