MULTIPLEXING ATM TRAFFIC STREAMS WITH TIME-SCALE-DEPENDENT ARRIVAL PROCESSES

This paper presents a flexible traffic model which is capable of descr ibing traffic dynamics on a variety of time-scales associated with bro adband packet networks such as ATM. The model is applied to the study of Non-Deterministic Periodic (NDP) sources as well as Variable Bit Ra te (VBR) video sources in which cells are delivered at a sub-frame lev el referred to as a slice. An efficient numerical technique is present ed for the study of a finite-capacity multiplexer under an input proce ss determined by the superposition of N of the proposed traffic models . Numerical results support the assertion that the time-scales at whic h variations in a cell arrival stream occur have a significant impact on multiplexer performance, thereby illustrating the relevance of the proposed modeling and analytical techniques.
