∗ Partially supported by FAPESP (under grants 96/12372-2 and 97/14449-5) and CPqD-Telebrás (contracts 7500/856/97 and 7800/825/97). Abstract – This paper presents a realistic model for Ethernet LAN Traffic that takes into account the network constraints. The design of the model is presented along with a brief description of SimATM, an ATM network simulator developed at UNICAMP. The resulting self-similar model is compared with real network data from Bellcore Ethernet traffic measurements. Results of simulations with synthetic traffic traces are presented for a simple ATM network. These results clearly indicate that simple Poisson traffic models underestimate real network losses by several orders of magnitude.
