Abstract
More and more applications on the Internet would benefit from Quality of Service provisioning. Unfortunately, the IP-based Internet works according to a best-effort model and gives no QoS guarantees. Thus, the (compared to Integrated Services) simple Differentiated Services architecture has been developed to provide a service better than best-effort. This paper presents components of the Differentiated Services architecture and shows the benefits of local pre-marking and traffic conditioning. This traffic conditioning is combined with a feedback architecture and a simple user interface where a user can express his or her request for more QoS via a simple button. The traffic is formed in a way that QoS is supported and no packet is discarded or is downgraded at the next domain. First results demonstrate the benefits of the approach in a real testbed.
