Abstract


In this paper we will explain the method of approximating the mean buffer occupancy in a packetspeech multiplexer. The model that we use is often used in literature for modelling the statistical multiplexer and that is - the fluid flow model with the ON/OFF packet traffic sources. Our idea is based on the indirect obtain of an approximate equation for the calculation of the mean buffer occupancy through the asymptotic approximation of overflow probability in the proposed model with an infinite buffer. Actually, usage of the results obtained by the two different approaches in analysis of the suggested modelcreates the possibility of extracting the equation for the approximate calculation of the mean buffer occupancy.
