There is a growing need to support real-time applications over the Internet. Real-time interactive applications often have multiple Quality-of-Service (QoS) requirements which are application specific. Provisioning QoS in the Internet through IP routing - Intserv or Diffserv - faces many technical challenges, and is also deterred by the huge deployment issues. As an alternative, application providers often build their own application specific overlay networks to meet their QoS requirements. This paper presents a unified framework which can serve diverse applications with multiple QoS constraints.
