Admission control is a mechanism used to restrict access to a computer network to some flows based on the current utilization level of the network resource. By regulating the number of on-going flows, admission control aims at preventing overloading, congestion and performance collapses, so that, accepted flows receive a sufficient level of Quality of(More)
This paper provides a contribution for NS-3 consisting of a new tool for generating Internet traffic. This tool is based on the Poisson Pareto Burst Process (PPBP), a Long-Range Dependent (LRD) model for network traffic. The PPBP model provides a simple and accurate network traffic generator that matches statistical properties of real-life IP networks. We(More)
HTTP video is quickly becoming a dominating type of traffic on the Internet, with popular services such as YouTube and Netflix being used by hundreds of millions of users daily, and showing ever-growing usage numbers. Understanding Quality of Experience (QoE) for these services is an important topic, and one that has been addressed in the literature.(More)
Over the course of the past year, millimeter wave-based (MMW) imaging systems have entered the market, been deployed, and been evaluated in various trial applications. The attractiveness of millimeter wave solutions is that they combine an excellent combination of technology maturity, low cost commercialization, and important performance attributes. These(More)
Many methods have been proposed in the literature to perform admission control in order to provide a sufficient level of Quality of Service (QoS) to accepted flows. In this paper, we introduce a novel data-driven method based on a time-varying model that we refer to as Knowledge-Based Admission Control solution (KBAC). Our KBAC solution consists of three(More)
The rapid growth of video traffic on the Internet raises many challenges for Internet service providers in managing their network resources. An emerging trend in this regard is the development of network management strategies to enhance the quality experienced by the end-users (Quality of Experience - QoE). In this paper, we introduce an admission control(More)
In this demonstration, we illustrate the behavior of a prototype implementation described in [3]. It consists of a web interface tool for a new data-driven admission control solution that we refer to as Knowledge-Based Admission Control (KBAC) solution. Our KBAC solution builds an up-to-date Knowledge Plane of the link behavior by feeding a mono-server(More)
