Abstract: Abstract We focus on the physical mechanism of phase transition between noncongested and congested phases in Internet traffic. We analyze the simplest model of packet transport protocol called stop-and-wait, which is an element of widely-used TCP/IP protocol. Our simulation clarifies that the stop-and-wait protocol can reproduce the same phase transition as appears in actual Internet traffic. The most important result is that the exponent of power-laws at the critical point has the same value as one in real traffic trace. We also show that a simpler model, which omits feedback control, shows a phase transition behavior, but, the power law exponent is different from the observed one. Our simulation clarifies the minimal network topology for generating 1/f fluctuation when using the stop-and-wait algorithm.
