Abstract This thesis focuses on traffic characterization and the evaluation of Call Acceptance Control methods. Two different models, which can be used to characterize real-time services, and the index of dispersion, an index that can be used to determine the variability of a source, are considered. A technique which can be used to achieve an accurate index-of-dispersion estimate, by observing only the actual traffic flow, is presented and evaluated. Several analytical results, that can be used in CAC, are described and evaluated, with an emphasis placed on a result which is independent of traffic source models and therefore appears to be the most promising. Based on this result, we can determine the load of an ATM switch using the average bit rate and the index of dispersion for each traffic source. Evaluation is based on simulation experiments, which use a fast-estimation technique that reduces dramatically the amount of time required to achieve an accurate cell-loss-rate estimate.
