Performance studies of ATM switches typically consider the binomial distribution to model the traffic behavior at the input of the switch. For instance, the basic knockout principle for the packet loss performance measure, has been solved by considering the binomial assumption in most of the cases. In this paper, we have found that the binomial distribution remains essentially valid for modeling MPEG video traces at the input of the switch, however, in video- on-demand applications with multicasting, the binomial assumption is no longer valid. In this case we have found that the beta-binomial model for the knockout switch gives a better cell loss performance prediction.
