L'architecture de services différenciés (Diffserv) est une solution potentielle pour fournir une qualité de service (QoS) sur Internet. La plupart des études existantes se concentrent sur la différenciation des services entre quelques classes de services. Dans cet article, nous proposons une approche permettant d’obtenir une allocation équitable de tarifs pondérée par flux dans un réseau de services différenciés. Conformément à la philosophie de conception du modèle Diffserv, dans l'approche proposée, les routeurs principaux n'ont pas besoin de conserver les informations par flux. Un routeur périphérique ajuste le taux de transmission d'un flux en fonction du retour d'information transmis sur les paquets de contrôle, qui sont insérés par le routeur périphérique d'entrée et renvoyés par le routeur périphérique de sortie. Les routeurs principaux estiment périodiquement le taux de partage équitable de chaque flux virtuel et marquent les résultats dans les paquets de contrôle. Nous utilisons à la fois des simulations et des analyses pour évaluer les performances de l'approche proposée. Les résultats analytiques montrent que notre approche permet à un système de converger vers des allocations pondérées de taux équitables en un temps limité. Grâce aux résultats de simulation, nous pouvons valider davantage les résultats analytiques et démontrer qu’un meilleur débit peut être obtenu.

Abstract: The differentiated services (Diffserv) architecture is a potential solution for providing quality of service (QoS) on the Internet. Most existing studies focus on providing service differentiation among few service classes. In this paper, we propose an approach which can achieve per-flow weighted fair rate allocation in a differentiated services network. Following the design philosophy of the Diffserv model, in the proposed approach core routers do not need to keep per-flow information. An edge router adjusts the transmission rate of a flow based on the feedback carried on control packets, which are inserted by the ingress edge router and returned by the egress edge router. Core routers periodically estimate the fair share rate of each virtual flow and mark the results in control packets. We use both simulations and analysis to evaluate the performance of the proposed approach. The analytical results show that our approach allows a system to converge to weighted fair rate allocations in limited time. Through the simulation results, we can further validate the analytical results, and demonstrate that better throughput can be achieved.
