Multiplexing ATM Tra c Streams withTime - Scale - Dependent Arrival Processes

This paper presents a exible traac model which is capable of describing traac dynamics on a variety of timescales associated with broadband packet networks such as ATM. The model is applied to the study of Non-Deterministic Periodic (NDP) sources as well as Variable Bit Rate (VBR) video sources in which cells are delivered at a sub-frame level referred to as a slice. An eecient numerical technique is presented for the study of a nite-capacity multiplexer under an input process determined by the superposition of N of the proposed traac models. Numerical results support the assertion that the timescales at which variations in a cell arrival stream occur have a signiicant impact on multiplexer performance, thereby illustrating the relevance of the proposed modeling and analytical techniques.
