Traffic shaping of a tagged stream in an ATM network: approximate end-to-end analysis

Traffic streams-originally shaped to comply with desired traffic descriptors-may suffer substantial distortion within an ATM network due to statistical multiplexing. As a consequence, traffic re-shaping within the network may be necessary. In this work the modification of a tagged traffic stream due to a series of multiplexing operations is studied. The standard FCFS service policy, as well as a peak-rate enforcing multiplexing discipline, are considered. Tagged cell delay, jitter and inter-departure processes are considered for the characterization of the tagged traffic stream.
