Abstract

Both Long Range Dependence (LRD) and Short Range Dependence (SRD) co-exist in Internet traffic. We review the transformation between LRD and SRD at different levels of traffic superposition (ISP tiers) and propose a simple combined framework for traffic modeling for source, access and core (backbone) networks. We use flow level (TCP and UDP) entities for structural modeling of Internet traffic as these Layer 4 entities are invariant to network topology, medium and its provisioning. This flow level framework emphasizes the role of Pareto distribution in source modeling; and, Weibull distribution in access and core network traffic modeling.
