QoS Guarantee for Self-Similar Traffic Flows

Network quality of service in future needs to consider the impact of inherent self-similar. Traditional networks ignore this. The paper utilizes Fractional Brownian Motion model to build a network model, which improves statistical multiplexing efficiency by controlling effective bandwidth and provides services by admission control. Experiment verifies that FBM model can realistically describe packet traffic flows, predict their performance, make full use of network recourses, and make up the deficiency of conventional queue models.
