The increase and the evolution of the Internet during the two last decades have significantly increased the complexity of communication techniques in this network, as well as its traffic characteristics. Thus, while the Internet is requested to provide services with guaranteed qualities, the bad knowledge of its characteristics and its traffic lead to the failure of all proposals made for this purpose. My work during the 6 last years proposed to use Internet monitoring for solving this issue, and shows how this new (new in the Internet) "science of measurements" provides essential information for the technical evolution of networks. This work then essentially deals with the characterization and analysis of the Internet networks and traffic, whose results lead to the design of a new Internet architecture based on a global monitoring system which allows a significant increase of the Internet performance and quality of service. Note also that the results on traffic characterization allow the classification of traffic anomalies into legitimate (as flash crowds) and illegitimate (attacks), and open new ways for the security of communication networks
