Abstract [en]

In order to carry real-time traffic like video, IP networks -- especially intranets -- recently began to deal with different levels of priority for communication flows. Traffic prioritization is the key to meeting the demands of real-time traffic, which are much more stringent than mere data traffic, such as file transfers. Now that the question: "How should we specify different levels of priority?" is reasonably understood, the challenge is to answer this new one: "How should we charge for these different levels of priority?"

This document discusses the introduction of Quality of Service (QoS) in the corporate network of a large industrial enterprise. Its main contributions are a charging model for different types of traffic with different levels of priority, and a network simulation for verifying the impact of a QoS implementation.

Abstract [fr]

Afin de pouvoir transporter le trafic temps réel comme la vidéo, les réseaux IP, notamment les intranets, ont récemment commencé à intégrer différents niveaux de priorités pour les flux de communication. Par ce biais, il est possible de satisfaire les exigences de ce type de trafic qui sont bien plus contraignantes que celles affectant un trafic de type transfert de données. Aprés la question: "comment sépcifier différents niveaux de priorités?" se pose aujourd'hui la question: "comment facturer l'utilisation de ces différents niveaux de priorités?"

Cette thèse traite de l'introduction de la Qualité de Service (QoS) dans le réseau IP d'une grande entreprise industrielle. Elle présente  un modèle de facturation différenciée pour différents types de trafic plus ou moins prioritaires, et une simulation de réseau pour vérifier l'impact de l'implémentation d'un modèle de QoS.
