Abstract
Analysis and modeling of Internet traffic is essential for network performance evaluation. Although, some Internet traffic models have been proposed previously, we still lack a traffic model capable of handling huge traffic traces and offering an acceptable queuing performance at the packet level. In this paper, we present a new approach to model Internet traffic that fulfills these two goals. Our model is based on a Mixture-ARFIMA time series model. The model can handle huge traffic traces using aggregate count processes and it offers good queuing performance by modeling packet streams inside the traffic trace instead of modeling the whole trace as one packet stream. We validate our approach on different traffic traces. Our experimental results show a better performance using this approach compared to old methods.

Abstract
In this paper, an analytic approximation is derived for the end-to-end delay-jitter incurred by a periodic traffic with constant packet size. The single node case is considered first. It is assumed that the periodic traffic is multiplexed with a background packet stream under the FCFS service discipline. The processes governing the packet arrivals and the packet sizes of the background traffic are assumed to be general renewal processes. A very simple analytical approximation is derived and its accuracy is assessed by means of event-driven simulations. This approximation is then extended to the multiple node case yielding a simple analytical approximation of the end-to-end jitter. This approximation is shown to be fairly accurate in the light to moderate traffic conditions typically encountered in IP core networks.
