Allocation Schemes of Ressources with Downgrading
Christine Fricker, Fabrice Guillemin, Philippe Robert +1
We consider a server with large capacity delivering video files encoded in various resolutions. We assume that the system is under saturation in the sense that the total demand exc…
Analysis of an offloading scheme for data centers in the framework of fog computing
Christine Fricker, Fabrice Guillemin, Philippe Robert +1
In the context of fog computing, we consider a simple case when data centers are installed at the edge of the network and assume that if a request arrives at an overloaded data cen…
Impatience in mobile networks and its application to data pricing
Salah Eddine Elayoubi, Christine Fricker, Fabrice Guillemin +2
We consider in this paper an import Quality of Experience (QoE) indicator in mobile networks that is reneging of users due to impatience. We specifically consider a cell under heav…
A versatile and accurate approximation for LRU cache performance
Christine Fricker, Philippe Robert, James Roberts
In a 2002 paper, Che and co-authors proposed a simple approach for estimating the hit rates of a cache operating the least recently used (LRU) replacement policy. The approximation…
Impact of traffic mix on caching performance in a content-centric network
Christine Fricker, Philippe Robert, James Roberts +1
For a realistic traffic mix, we evaluate the hit rates attained in a two-layer cache hierarchy designed to reduce Internet bandwidth requirements. The model identifies four main ty…
Traffic Capacity of Large WDM Passive Optical Networks
Nelson Antunes, Christine Fricker, Philippe Robert +1
As passive optical networks (PON) are increasingly deployed to provide high speed Internet access, it is important to understand their fundamental traffic capacity limits. The pape…
