The main objective of our work in this domain is a better monitoring of the Internet and a better control of its resources. In the monitoring part, we work on new measurement techniques that scale with the fast increase in Internet traffic. We also work on the utilization of measurements to infer the topology of the Internet and to localize any distributed resource. In the network control part, we focus on new solutions that improve the quality of service to users and that maximize the operators' revenues. Another objective is understanding the dynamics of the core mechanisms of peer-to-peer file sharing protocols. In particular, we focus on file transfer efficiency. We also want to investigate the existence and the potential impact of chaotic behaviors in the Internet. Understanding such behaviors is a scientific challenge, with the potential of a significant impact, especially concerning applications based, e.g., on chaos control, or resonances in chaotic systems.

Next, is a sketch of our main contributions in this area.
