Properties of the ATM traffic process is discussed, especially the mixture of traffic from different types of sources, the modelling of various mixtures, and the effects of multiplexing and splitting. These properties ought to be taken into account in traffic activities like analysis, simulation and synthetic traffic generation. The paper focuses on the correlation structure of a cell stream at various points in the network. Preliminary results from a simulation study are presented. The main conclusions are: The traffic from actual traffic sources have a large long term correlation. The buffering/multiplexing and splitting has a moderate coloring effect on this correlation. The results so far give no reason to assume that the cell arrival process may be approximated by a Poisson type of process after buffering and splitting. No model capturing the most salient properties of a buffered/multiplexed and split traffic stream is so far proposed and work should be directed toward the development of such a model.
