Analysis of a priority leaky bucket regulator for virtual path traffic in ATM networks

The proposed priority traffic regulator maintains a separate cell buffer for each traffic priority to be able to trade off cell delay and loss (or tagging) on the basis of the quality of service requirements for each priority class. A versatile Markovian point process model is adopted for both priority and low-priority sources. The joint buffer content distribution and cell loss probabilities of the two priority classes are obtained. The obtained results capture the effect of the shaper/policer and source parameters on the cell loss/delay performance, and may be used for design optimization.
