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

In this paper, 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.
