Group Communication Support for Distributed Multimedia and CSCW Systems

Maetro is a middleware support tool for distributed multimedia and collaborative computing applications. There applications share a common need for managing multiple sugroups while providing a possibly different quality-of-service guarantees for each of these groups. Maestro's functiuonality maps well into these requirements, and can sinificantly shorten the development time of such applications. In this paper, we report on Maestro, and demonstrate its itility in implementing IMUX, a pseudo X-server (proxy) for collaborative computing applications. Examples of other multimedia applications that benefit from Maestro appear in the full version of the paper.
