Analysis of TCP congestion control using a fluid model

In this paper we develop an analytical fluid model for TCP Reno based on delay differential equations. Using this model, we have developed a prototype for a fluid based simulation tool for TCP. We empirically validate this model by matching the window, throughput and queue evolution curves obtained from the model to that offered by a simulation output. We claim that this analytical model provides the basis for an analyzer that can complement simulators that perform a packet by packet simulation.
