Cell Loss Analysis of Broadband Switching Systems Carrying Vbr Video Traac

Many diierent traac models have beenproposed for the data generated by variable bit rate (VBR) video coders. It has been observed in simulation studies that use of diierent coders results in a wide variation in predicted cell loss statistics. In this paper, several models are studied, and their predictions of network performance compared to those obtained using real data. A quasi-stationary analysis technique is used to obtain analytic approximations for some of these cell loss statistics.
