AN ANALYTICAL PARADIGM TO CALCULATE MULTIPLEXER PERFORMANCE IN AN ATMMULTIMEDIA ENVIRONMENT

In this paper a finite-buffer discrete-time approach is presented in o rder to analyze the performance of a multiplexer loaded by N multimedi a sources. For this purpose the emission process of each multimedia so urce is defined as the superstitution of heterogeneous correlated emis sion processes, each of which models one monomedia source as a Switche d Batch Bemoulli Process (SBBP). In order to model the intermedia rela tionships, the Markov chain underlying each SBBP consists of a 2-state process, where the transition probabilities are functions of the stat es of the other monomedia sources. Correlation functions are derived f or each monomedia source as well as for the multimedia source as a who le. The proposed analytical model is used to calculate the loss probab ility and the delay jitter pdf for each media in an ATM multimedia mul tiplexer structure. The effectiveness of the proposed paradigm is show n by means of various examples in a case study, (C) 1997 Elsevier Scie nce B.V.
