On the efficiency of statistical—bitrate service for video

Abstract

The provisioning of quality of service by means of statistical multiplexing has been an alluring research idea for the last decade of teletraffic research. In this paper we question the efficiency of statistical bitrate service which is the standardized representation of this operational mode for ATM networks. Our argument is that the amount of information needed about a traffic source in order to· attain a fair multiplexing gain is beyond what is captured in the standard's three-parameter traffic descriptor.
