Abstract

When a variable bit rate (VBR) video bitstream is transmitted into a network, the channel utilization is dependent on the maximum peak value of the traffic pattern and improved by reducing the peak rate. A lower bound on the transmission rate is derived from the given traffic cells. Based on the transmission rate constraint, the optimal bandwidth that is needed to meet the delay requirement during an allocation interval is also derived. From the delay bound and the constraints, we demonstrate that the traffic has been made as flat as possible
