(m,k)-frame: A Method to Control the Quality of Service in Distributed Multimedia Systems

Abstract

International audienceMultimedia applications usually manage large quantities of data in the form of frames of certain types. To ensure a good trafic of these frames through the network, temporal constraints must be respected when sending and receiving these frames. If the temporal constraints are not met, then the quality of service (QoS) provided to users decreases. In this paper, we exploit some results obtained in QoS management in Real-Time Database Systems (RTDBSs), and we apply them to multimedia applications, because of similarities existing between these two fields. We propose a new method allowing to control the QoS provided to clients according to the network congestion, by discarding some frames when needed
