Abstract	In order to realize multimedia applications such as VOD (Video-on-Demand) over highspeed networks, suitable QoS (Quality of Service) of the continuous media such as audio and video have to be guaranteed in accordance with users' requirements, available computing and network resources during the service session. In this paper, we introduce the Media Coordinate System which provides end-to-end QoS guarantee and negotiation functions consistently from the application through network layers. Within these QoS control functions we introduce a packet rate control method to reduce the packet loss, and a frame rate control method to maintain the frame rate at a constant under the dynamic load conditions. We implemented the media coordinate system as a prototyped Video-on-Demand system and evaluated the performance of these control functions. Through these performance evaluations, we could justify the usefulness of our suggested media coordinate system.
