✦ Synopsis

This paper considers packetized voice and video traffic incoming to an ATM multiplexer. Each voice and video source 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 modelled by the superposition of two MMPP(2) processes, denoted 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 numbers of sources. Results of the proposed method are also compared with those of Heffes and Lucantoni (IEEE

This paper studies the interdeparture process in a mathematical model of an ATM multiplexer. The technique is based on a discrete-time queueing model of k input queues feeding one output queue, a situation commonly arising in ATM switches. The process between input queues and output queue is analyse
