Abstract
Having its roots in the military ARPANET, conceived as a data transport network with a focus on resilience, the Internet supports only a best-effort service model, where all packets are treated the same way, therefore providing a single level of service. Now that the Internet is becoming a ubiquitous global communication infrastructure, new applications are emerging with more demanding and diversified requirements than data transport. Internet telephony, for example, has much stricter delay requirements than remote terminal, the most demanding of the original applications. The deployment of other service models providing better quality of service (QoS) is of great importance for the transport of these new applications.
