Paper Abstract

We study a queuing system having a mixture of special semi- Markov process (SSMP) and Poisson arrivals as the input process, where the Poisson arrival is regarded as interfering traffic. It is shown by numerical examples that the SSMP arrivals receive worse service than Poisson arrivals, i.e., the main waiting time of SSMP customers is longer than that of Poisson customers. We also propose a model of Moving Picture Experts Group (MPEG) frame arrivals as an SSMP batch arrival process. This model captures two features of the MPEG coding scheme: (1) the frequency of I, P, and B frames in a Group of Pictures, and (2) distinct size distributions for the three frames. The waiting time of each ATM cell generated from the frames is evaluated in the numerical examples. It is found that the waiting time characteristics are rather different among some real video data.
