Study on scaling behavior of heterogeneous traffic in modern networks

Two regime scaling behaviors has been proved to exist in Most of modern networks, i.e., self-similar scaling over large time scales and multifractality in sub-second small scales, but single multiscaling regime could not be fit in any circumstance, especially as the heterogeneous traffic composition appears more and more sophisticated in modern networks. Scaling behavior should be analyzed to verify the existence of self-similar or multifractal scaling in each range of scale. This paper will take heterogeneous traffic mixed by LAN and WAN in modern networks for example, and try to look into the characteristic of composition which aggregate the whole traffic flow, finally prove that with consistent extent of burstiness in traffic which aggregate enough TCP connections , self-similar is well kept, on contrast, for the traffic aggregated by less connection, unstable extent of burstiness dominate, and non-scaling behavior is observed in small scales rather than multifractility, autocorrelation function helps to explain more.
