Automatic Management of the QoS within an Architecture Integrating New Transport and IP Services in a DiffServ Internet

Lots of research works have been performed for about ten years around the QoS problem in the Internet, both but separately at the Transport and at the IP levels. Taking into account the emerging traffic engineering-based QoS solutions (Diffserv-oriented), this paper targets the integration of new Transport services and protocols together with these solutions. Starting from performance measurements performed over a national DiffServ platform, contributions exposed here deal with the proposition and the implementation of a session level protocol allowing the application programmers to be masked with the complexity of choosing the underlying new Transport and IP services, still being provided with a per flow QoS.
