|Abstract:||Broad-band. ,networks based on asynchronous transfer mode (ATM) have to support traffic with widely different traffic characteristics and quality of service requirement. In this dissertation, a dynamic connection admission controller (CAC) that supports cell loss requirements is discussed. The CAC algorithm explicitly computes the equivalent bandwidth required to support each class of connections based on on-line observations of aggregate traffic statistics as well as the declared parameters. To characterize the aggregate traffic stream Gaussian approximation, is used. Fuzzy control strategy is used to combine the model and measurement results to derive simple closed-form formulas to estimate the equivalent bandwidth in real time. The algorithms for variable bit rate traffic profiles have been simulated and the results show that the system utilization can be substantially improved by appropriately tuning the fuzzy logic controller to combine traffic characteristics deduced from the declared parameters and traffic measurements.
