Abstract : In the first part of this thesis, we present a general overview of our contributions in networking. The end to end principle and the Application Level Framing concept had major impact on network architecture in the last decade of the twentieth century. We studied protocols and applications architecture focusing on both scalability and new services aspects. Our activities on high performance protocol architecture represent therefore an important research direction and are described in the first chapter of this thesis. Many researchers also addressed multicast and quality of service support on the Internet. We also worked on this topic with a specific approach: we “believed” in multicast but not in QoS. Unfortunately neither one finally was deployed in a large scale on the Internet. Our contributions in this domain are described in chapter two. The network and in particular link heterogeneity is also an important factor: the solutions that were proposed to wired (and reliable) networks were not adequate for heterogeneous environments integrating links with different characteristics. Our contributions in this domain and in particular on unidirectional link routing are presented in the third chapter. The ossification of the Internet pushed many researchers to claim that “disruptive” architectural ideas should be considered. These new architectural considerations should take into account the interest of the different stakeholders in the future Internet. The difficulty to immediately deploy such disruptive ideas resulted in contributions in “overlay” layer. In parallel, work on the definition of a global environment to foster and evaluate networking innovations is being developed and deployed. Our activities in this domain are described in the fourth chapter of this thesis. The second part of this thesis contains the detailed presentation of three selected contributions covering the different topics of interest to us during the last fifteen years.
