Résumé: Many techniques have been proposed to evaluate the performance of ATM networks carrying VBR video traffic. The choice among these techniques may not be straightforward for researchers in other areas of computer networks. The aim of this work is to focus on three techniques that are based on two source models, and present a comparative study for them. As it will be shown, it is very difficult to have a perfect modeling technique that fits into all situations. The added complexity of multimedia traffic will make such task unfeasible. Also, a look into the situations of advantageous applicability of each one of these techniques, along with possible limitations and drawbacks will be given.
