Abstract:

This paper presents a novel network device being located in network edge nodes. It provides a solution for QoS guarantees to certain flows on a congested link by focussing packet discard on selected flows. Unlike IntServ solutions like RSVP, our approach only requires minimal signalling and provides both efficiency and scalability. In this paper, we first describe the ideas of our QoS device and then provide first results from a fast-track simulation model implementing a lightweight version of our approach
