Skew performance evaluation in an ATM multimedia multiplexer

The skew affecting a multimedia traffic stream when N multimedia streams are mixed in an ATM multiplexer is evaluated. To this purpose a multimedia source is modeled by an arrival process defined as the superposition of heterogeneous correlated arrival processes, each of which models one monomedia source by means of an Markov modulated Bernoulli process (MMBP) process whose transition probabilities are functions of the state of the other monomedia sources.
