—The goals of the present contribution are twofold. First, we propose the use of a non-Gaussian long-range dependent process to model Internet traffic aggregated time series. We give the definitions and intuition behind the use of this model. We detail numerical procedures that can be used to synthesize artificial traffic exactly following the model(More)
Available bandwidth – as well as capacity or achievable bandwidth – on a path or a link is one of the very important parameters to measure or estimate in a network: it is of high interest for many networking functions (routing, admission and congestion control, load balancing, etc). Active probing techniques provide the easiest and the more flexible(More)
How to provide quality of service (QoS), has been a major issue for the Internet for the past decade. Though many proposals have been put forward in the areas of differentiated and guaranteed services, none have met the needs of users and operators. Efforts have been stymied by the complexity of the Internet, its myriad systems of interconnection, and by(More)
This paper deals with both enforcing and charging end-to-end Quality of Service (QoS) and differentiated services in the Internet. Today, much work for optimizing QoS and defining charging mechanisms accordingly is related to low network layer (up to IP), and the current proposals under the spotlights are VPN, CDN, (over)-provisioning, and of course(More)
