A Stochastic Map Model of Phase Transition in Internet Traffic

Authors: Kensuke Fukuda, Hideki Takayasu, Misako Takayasu


We analyse the macroscopic dynamics of packet flow density in a WAN from the standpoint of statistical physics. Our results show the existence of a phase transition in macroscopic Internet traffic flow, which is characterized by three typical behaviors. We propose a simple autoregressive map model based on empirical phase transition phenomena, and show that it can reproduce the basic properties of actual traffic.
