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 and growth of its size. We proposed solutions for a fast and accurate identification of Internet traffic based on packet size statistics. We also studied the feasibility of inferring path metrics as the delay and the bandwidth from indirect measurements. In the network control part, we focus on new solutions that improve the quality of service to users by a better management of network resources and by a more efficient tuning of applications that take into account the constraints posed by the network. In this direction we propose efficient message drop and scheduling mechanisms for Disruption Tolerant Networks, as well as distributed topology-aware algorithms for the scheduling of communications among members of a wireless community interested in sharing data files among each other.

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