Fixed and Adaptive Model-Based Controllers for Active Queue Management

Abstract

In this paper we present new model-based controllers for active queue management (AQM) supporting TCP ows. Our control design is based on linearization of a previously developed TCP model using uid ow and stochastic di erential equations. An AQM using a simple PI controller is shown to signi cantly outperform RED AQM. However, we show that both AQMs are… (More)
