Traffic generator model for an n-node network

In the paper a model of the traffic in the LAN is presented. In the model the most important components influencing the network traffic are taken into account. Namely, the transmission protocols and information buffering, operational systems and queuing algorithms as well as users' behavior working with the network applications are considered. The model is based on an “on-off” function. It has been shown that self-similarity of traffic measured by the Hurst parameter changes from almost 1.0 for very low frequencies to 0.5 for high frequencies. Generated and real traffic in a LAN network were compared. Implications, which are derived from the model, are described in the conclusion.
