In this paper, first we present an effective bandwidth equation for multifractal traffic based on a multiplicative cascade model. Merging the effective bandwidth to the effective envelope concept from the Statistical Network Calculus, we compute end-to-end performance bounds for real multifractal network traffic. Using these bounds, we propose an admission control scheme that guarantees quality service in terms of data loss probability and delay through the obtained effective envelope for the MWM (Multifractal Wavelet Model) multifractal model. Through simulations, we compare the number of flows admitted using effective service curves corresponding to different types of traffic flow schedulers for the fBm (fractional Brownian motion) and MWM traffic models.
