Abstract: This paper proposes the Stochastic Petri Nets (SPN) formalism to model IP networks loaded with traffic resulting from a set of ON-OFF finite TCP-Reno connections. The approach is based on separate model descriptions of the TCP connection latency to transfer a finite number of packets and the IP network links; the two models are iteratively solved using a fixed point method. The overall model parameters are the primitive network characteristics; the model solution yields an estimation of the packet loss probability, the average completion time to transfer a finite number of packets over a TCP connection as well as the distribution of the completion time. The validation of the proposed approach and the future extensions to this work will also be discussed.
