Multimedia applications must adjust their QoS according to the heterogeneous terminals with variable QoS requirements and support.
Introduction
During the last decade, the multitude of advances attained in terminal computers, along with the introduction of mobile hand-held devices, and the deployment of high speed networks have led to a recent surge of interest in Quality of Service (QoS) for multimedia applications. Computer networks able to support multimedia applications with diverse QoS performance requirements are evolving. To ensure that multimedia applications will be guaranteed the required QoS, it is not enough to merely commit resources. It is important that distributed multimedia applications ensure end-to-end QoS of media streams, considering both the networks and the end terminals. The degradation in the contracted QoS is often unavoidable, thus there is a need to provide real-time QoS monitoring that not only is...
