Garanties de performance pour les flots IP dans l'architecture Flow-Aware Networking

Abstract : The thesis deals with the realization of a Quality of Service architecture that breaks with traditional approaches, and allows end-to-end performance guarantees for the traffic. The Flow-Aware Networking approach considers the traffic at the flow level, for which simple but robust traffic models lead to a fundamental relationship between the resources offered by the network, the demand and the obtained performance. In particular, the Cross-Protect router architecture proposes the combination of a fair queueing scheduler, and an admission control so as to implicitly ensure the performance of both streaming and elastic flows, without the need for any marking nor signalization protocol. In such a context, we consider the sizing of router buffers, the introduction of fair queueing scheduling inside the network and its impact on the performance of TCP protocols, as well as the realization of a suitable admission control algorithm. Finally, a declination of this architecture for the access network is proposed.
