A Model for the Analysis of Intramedia Synchronization in a Multimedia Data Stream Served by an ATM Multiplexer

In this paper the jitter suffered by the cells of the monomedia traffic streams which compose a multimedia data flow loading an ATM Multiplexer is analyzed. To this aim, a multimedia source is modeled as an arrival process defined as the superposition of heterogeneous arrival processes, each of which models one monomedia source. In order to capture the time relationships existing between the monomedia sources of the multimedia stream, they are modeled as mutually correlated Interrupted Bernoulli Processes. Correlation functions are derived for each monomedia source as well as for the multimedia source as a whole. A case study is shown in order to assess the possibility of analytical treatment of the proposed paradigm.
