A Quasi-Stationary approach to evaluate streaming traffic performance was recently proposed, which combines in a simple way the traffic variations at flow and packet time-scales. The present paper elaborates on it, by specifically focusing on the multi-class/multi-rate aspects of the model. A first original contribution is the theoretical description of flow peak rates in terms of a continuous distribution. Then, a set of simulations is reported which shows in some simple cases, e.g., a multiplex of constant bit rate flow classes, the suitability and efficiency of the approach. Finally, a preliminary trace-driven simulation experiment, although not fully satisfactory, shows some need for explicitly taking into account the flow peak rates in performance evaluation.
