Abstract:

In this report we study a previously developed linearized model of TCP and AQM. We use classical control system techniques to develop controllers well suited for the application. The controllers are shown to have better theoretical properties than the well known RED controller. We present guidelines for designing stable controllers subject to network parameters like load level propagation delay etc. We also present simple implementation techniques which require a minimal change to RED implementattions. The perfomance of the controllers are verified and compared with RED using ns simulations. The second of our designs, the PI controller is shown to outperform RED significantly.
