Abstract

This paper details work in progress to produce a Media-enhanced virtual meeting place using Quality of Service Management components to cope with heterogeneous networks and end-systems. In recent years there have been great advances in the fields of Virtual Reality, streamed Audio and Video, and network technology. The combination of these three technologies has the potential to produce a media-rich realistic environment. Such an environment provides intuitive 3D navigation, interaction with other participants, and they selective audio-visual content. However, varying network performance, processing speed, and workload, have severe effects on the usability, performance and effectiveness of such an application. For this reason a Quality of Service (QoS) management is needed to adapt the application, and maintain usability and effectiveness at the highest level possible, under varying resource conditions.
