A Self-configuring Proportional-Integral Controller for AQM Routers Supporting TCP-like Flows

چکیده
In this paper we propose a self-configuring proportional-Integral (S-PI) controller based on our enhanced TCP-AQM joint system model and root-locus analysis. By introduction of root-locus method in classical control theory, we focus on the discussion on response time and stability. Comparing with static-configured PI controller in [11] which can’t work well under various network dynamics according to our analysis and simulations, our S-PI controller has a faster response time without sacrificing stability and even have a larger stability margin. Simulations under various situations validate the advantages of our algorithm over PI controller.

In this paper 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, propogation delay...

In this paper, we apply an anti-windup scheme for improving the performance of a conventional ProportionalIntegral (PI) controller for Active Queue Management (AQM) supporting TCP flows. When a PI controller is used for AQM, the “windup” phenomenon of the integral action can cause performance degradation because the packet drop probability is limited between 0 and 1. Therefore we model TCP/AQM ...
