Understanding the dynamics of a TCP-AQM System: An Analytical Approach

E. Altman, P. Dube, P. Nain


In this paper, we analyze the dynamics of RED when interacting with TCP controlled trafic. We propose a singular perturbation methodology for the analysis, which explits a decomposition into two time scales that characterizes RED: a fast time scale for the instantaneous throughput and queue length and a slow time scale for the variations of the averaged queue length.
