Stochastic Differential Equation Modeling and Analysis of TCP-Windowsize Behavior

Overview This paper presents new modeling and analysis technique for characterizing the steady state performance of a TCP flow. It invert the loss process in this model; by treating loss events arriving at the sour source as a Poisson stream rather than pack packets going out on the network with some loss probability. This enables us to model the window size behavior as a Poisson Counter driven Stochastic Differential Equation and perform analysis. The data collected is used to validate the modeling and analysis technique. Results indicate that this model is able to capture the behavior of TCP throughput quite accurately. The technique enables simple fluid analysis of TCP and other TCP-like congestion control mechanism.
