Today, the Internet has become the most important communication infrastructure of our society. It enables worldwide users (individual, groups, and organizations) to access and exchange remote information scattered all over the world. Currently, due to the growing needs in telecommunications (Video on Demand, Video-Conference, VoIP, etc.) and the diversity of transported flows, the Internet still does not meet the requirements of integrated service networks that carry multimedia data traffic with a high quality of service (QoS). The main drivers of this evolution are the continuous growth of the bandwidth requests, the promise of cost improvements, and finally the possibility of increasing profits by offering new services. First, the Internet does not support resource reservation which is primordial to guarantee an end-to-end QoS (bounded delay, bounded delay jitter, and/or bounded loss ratio). Second, flow packets may be subjected to unpredictable delays and thus may arrive at their...
