A theoretic analysis model for VBR video traffic in ATM networks

Up to now, there is no analysis model suitable to describe the Gamma distribution and exponential autocorrelation characteristics presented in the literature, which is very important for video traffic. In this paper, we propose such a video model called the C-DAR(1) model. We believe that it is the first model meeting the distribution and correlation characteristics of video conference traffic. A scheme is given to link the continuous-time Markov chain model with a discrete-time one. A doubtful conclusion in the work of Skelly et al. (1993) is discussed.
