Abstract

With the increasing popularity of multimedia applications, videodata represents a large portion of the traffic in modern networks.Consequently, adequate models of video traffic, characterized by ahigh burstiness and a strong positive correlation, are veryimportant for the performance evaluation of network architecturesand protocols. This paper presents a method that uses the Whittleestimator to choose, between several models for VBR video trafficbased on the M/G/∞ process, the one that gives rise to abetter adjustment of the spectral density, and therefore of thecorrelation structure, of the traffic to model.
