Abstract: ATM provides the flexibility of supporting different traffic classes with diverse flow characteristics while guaranteeing the different quality of service (QOS) requirements. In this paper, with both cell loss probability and maximum cell delay of each traffic class as the QOS requirements, an efficient algorithm is developed to determine the minimum capacity required to satisfy all the QOS requirements when multiple traffic classes of on-off sources are multiplexed onto one virtual path (VP) by applying the Markov Modulated Deterministic Process (MMDP) method. We then consider the problem of assigning traffic classes to VPs so as to minimize the total capacity required. A simple algorithm to produce a near optimal assignment has also been proposed. The performance of the proposed algorithm has numerically been compared to that of the optimal assignment.
