A New Model of VBR Video Traffic on ATM Networks with Gamma Distribution

摘要

In this paper, we proposed a new VBR video traffic model, a double first-order autoregressive Gama sequence, which can describe the real VBR video traffic better. The number of cells per frame of the model has characteristic of Gamma distribution. We give the definition of it and show some characters of it. Also, we study the method of parameter estimation. Simultion results show that the model cna meet the characters of real VBR video data sequence accurately. in the end, we point that the model has great sense in modeling the general traffic on ATM networks.
