Abstract :
This paper considers the packetized voice and video traffic incoming to an ATM multiplexer. Each of voice and video sources is approximated by a two-state Markov modulated Poisson process (MMPP(2)). We propose a method based on the asymptotic results of a renewal process to obtain the equivalent MMPP(2) parameters. The integrated voice and video sources are modeled by the superposition of two MMPP(2) processes, called as MMPP(4). The analysis of the superposed traffic in terms of buffer occupancy, cell loss probability, and delay is performed with an MMPP(4)/Er(k)/1/B queuing model considering different buffer sizes and number of sources. Results of the proposed method are also compared with those of Heffes and Lucantoni (1986) and Poisson approximation
