On the self-similarity of measurement-based admission controlled traffic

We focus on an admission controlled traffic scenario. Flows, characterized by heavy-tailed on/off periods, are admitted to a network link according to a measurement based admission control algorithm. Our simulation results show that the long range dependence of the accepted traffic aggregate is marginal, particularly when compared with that resulting from a traffic aggregate accepted by a parameter-based admission control scheme. Our results appear to suggest that measurement based admission control is a value added tool to dramatically improve performance in the presence of self-similar traffic, rather than being a mere approximation for traditional (parameter-based) admission control schemes.
