A Scalable QoS Device for Broadband Access to Multimedia Services

This paper presents the performance evaluation of a novel network device being located in network edge nodes. It provides a solution for relaxed QoS guarantees to certain flows on a congested link by focussing packet discard on selected flows. However, unlike IntServ solutions – e.g. RSVP – our approach only requires minimal signalling and therefore provides both efficiency and scalability. In this paper, we first describe the ideas of our QoS device and then provide a simulative performance analysis for different multimedia flow scenarios.
