Abstract

A microscopic description of packet transport in the Internet by using a simple cellular automaton model is presented. Therefore we introduced a generalized exclusion process which allows to study travel times of the particles (‘data packets’) along a path in the network. Computer simulations reveal the appearance of a free flow and a jammed phase separated by a (critical) transition regime. The power spectra are compared to empirical data for the RTT (Round Trip Time) obtained from measurements in the Internet. We find that the model is able to reproduce the characteristic statistical behavior in agreement with the empirical data for free flow and congested phase. Moreover the model shows, as observed in reality, critical behavior (1/f-noise) for paths with critical load.
