QoS provisioning as a generic telecom service is only useful if deployed end-to-end, so it must cover both the access segment and the interdomain segment of routes. This work focuses on the interdomain component of QoS architectures. Although the research community has been discussing several aspects of the problem, integrated architectures for true end-to-end QoS are still largely conceptual, especially if one considers mesh models and not simpler cascaded ones. Our inter-domain proposal combines offline service discovery and registration with real-time congestion notification, allowing us to significantly reduce the number of packets that were not suitably serviced, in the sense of fulfilling required Service Level Agreement constraints. We qualify our approach of dasiastatelesspsila since our proposal doesnpsilat use additional state in forwarding elements which is one of the most dramatic problems for interdomain scenarios.
