Several simulation and measurement studies have reported the well-known network traffic self-similarity and long-range dependency and the consequences for network performance. In the context of simulation, however, the impact of the number of sources has not been sufficiently emphasized for the generation of synthetic self-similar traffic. In this paper we describe a simulation scenario suitable for the testing of performance issues under self-similar traffic. Our analysis was centered on the effect of traffic aggregation over the self-similarity degree, determining the necessary number of sources to approach the verified relation H = (3 - min α)/2. Besides, we highlighted the performance of several Hurst parameters estimators for this type of simulation scenarios, identifying the most suited ones.
