A quantitive Model for Parameter Setting of RED with TCP traffic
Thomas Ziegler, Christof Brandauer, Serge Fdida (2001): A quantitive Model for Parameter Setting of RED with TCP traffic In: Proceedings of the Ninth International Workshop on Quality of Service (IWQoS), 2001, Karlsruhe, Germany, June 2001.
This paper systematically derives a quantitative model how to set the parameters of the RED queue management algorithm as a function of the scenario parameters bottleneck bandwidth, round-trip-time, and number of TCP flows. It is shown that proper stetting of RED parameters is a necessary condition for stability, i.e. to ensure convergence of the queue size to a desired equiligrium stat and to limit oscillation around this equilibrium. The model provides the correct parameter settings, as illustrated by simulations and measurements with FTP and web-like TCP flows in scenarios with homogeneous and heterogeneous round trip times.
