Analysis and evaluation of a scalable QoS device for broadband access to multimedia services

This paper presents the initial evaluation of a novel network device being located in edge nodes. It provides relaxed QoS guarantees to certain flows on a congested link by focussing packet discard on selected flows. In contrast to classical IntServ solutions, our approach 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 first results of our ongoing simulative performance evaluation and optimization.
