Transmitting video over ATM networks with a variable-bit-rate coding technique aims to optimize performance and to improve channel efficiency. Particularly the two-layer coding schemes that separate the coded bits into two priority streams are well suited for the ATM standard. This is achieved by giving different access priorities of the shared buffer to the two streams. In the paper, the authors derive a formula to determine the cell loss rates of the two priority streams for multiple VBR video sources under a simple access scheme. They also consider the problem of determining the optimal capacity and buffer allocation to satisfy the QoS requirement of the traffic.<>
