Implications of the self-similar behaviour of real traffic sources on the local queue occupancy in metropolitan area networks

Recent measurement analysis obtained over real testbeds show that multimedia applications produce aggregated traffic well-described by bursty stochastic processes which exhibit long-range dependence. The paper presents a simulation comparison between the behaviour of a DQDB MAN driven by different sources: real multimedia traffic (collected by experimental measurement) and stochastic models used to fit its self-similar nature. Our attention is particularly directed to self-similar traffics, modeled by fractional Gaussian noise processes.
