Abstract

Several traffic measurement studies have shown the presence of persistent correlations in modern networks. The use of stochastic processes able to capture this kind of correlations, as self-similar processes, has opened new research fields in network performance analysis, mainly in simulation studies, where the efficient synthetic generation of samples is one of the main topics. Although F-ARIMA processes are very flexible to capture both short- and long-range correlations in a parsimonious way, only off-line methods for synthesizing traces are efficient enough to be of practical use. In order to overcome this disadvantage, in this paper we propose a M/G/***-based efficient and on-line generator of the correlation structure of F-ARIMA processes.
