Abstract : This work focuses on quality of service in large scale packet switching networks and, more specifically, throughput guarantee for TCP flows. The differentiated architecture, defined by the IETF, also called DiffServ, provides three services : the guaranteed service, the assured service and the best effort service. The assured service was conceived for serving elastic flows such as TCP flows. Nevertheless some problems persist when it comes to assuring a TCP throughput. These past years, a consequent effort has been made in order to improve scheduling, classification and dropping mechanisms in routers so that they match the assured service specification as best as possible. Unfortunately, design choices and complex implementation are frequent limitations to their deployment in the real Internet. In this thesis, we propose an original conditioning approach for TCP flows allowing for a guarantee both for single and aggregate TCP flows. This solution is scalable.
