Distributed QoS Routing for Backbone Overlay Networks
Overview In recent years, overlay networks have emerged as an attractive alternative for supporting value-added services. Due to the difficulty of supporting end-to-end QoS purely in end-user overlays, backbone over-lays for QoS support have been proposed. This paper describes a backbone QoS overlay network architecture for scalable, efficient and practical QoS support. This architecture advocates the notion of QoS Overlay Network (referred to as QSON) as the backbone service do-main. The design of QSON relies on well-defined business relationships between the QSON provider, network service providers and end users. A key challenge in making QSON a reality consists of efficiently determining routes for end user QoS flows based on the service level agreements between the QSON provider and network service providers.
