N2 - We propose an admission control policy subject to a quality of service constraint for real-time traffic in a packet-switched network. Taking advantage of the statistical multiplexing of voice packets, the calls employ a multi-state source encoder whose state is determined by the level of source activity. Further, in each state, the source encoder outputs an embedded bit stream in the sense that any truncated version of the bit stream is meaningful. This makes it possible to drop some of the less significant packets and suffer some amount of quality degradation in order to handle the congestion problem. An optimal rate assignment among calls is performed which minimizes the average end-to-end distortion. Therefore, the network can admit more calls so long as the average end-to-end distortion is acceptable; consequently, the call blocking probability is decreased.
