Modeling to obtain the effective bandwidth of a traffic source in an ATM network

Describes and compares two classes of approaches to estimating the effective bandwidth of a traffic source of fixed-length packets (cells) in a high-speed network. In one class of approaches, the arrival times of the source are monitored and modeled by, e.g., a Markov-modulated Poisson process; the effective bandwidth of the model is then used to estimate that of the source. In the other class of approaches, points on the effective bandwidth curve of the source are estimated by monitoring the occupancy of buffers; an estimate of the effective bandwidth curve of the source is then found by interpolation and extrapolation using these points
