It has become clear that the traditional Poisson model of data network traffic is insufficient for dimensioning and analyzing the performance of real-life networks. Fractal models are more appropriate for simulating the self-similar behavior of data traffic. OPNET features the Raw Packet Generator (RPG) which contains several implementations of self-similar sources. This paper will present a comparison between measured LAN traffic and the different RPG models in OPNET Modeler. It describes the methods used to select a particular model. The different parameters that are used in the models (e.g. Hurst parameter) are discussed and realistic values for them are presented.
