چکیده

Multimedia desktop conferencing systems are gaining momentum and increasingly becoming a reality. In these systems, besides using audio, video and multi-user applications, users can share a vast number of single-user applications for collaborative work. In these systems, there are two basic architectures for sharing single-user applications, centralized and replicated. In this paper, we present the important issues involved in designing and implementing application sharing systems based on the replicated architecture. We show what type of objects need to be replicated, the specification of these objects and the different approaches for implementing the replication processes. The concepts presented were used in implementing JCE, a multimedia desktop conference system for sharing Java applications. RÉSUMÉ. Les environnements collaboratifs multimédia sont en train de gagner de plus en plus d’intérêt et deviennent une réalité. Dans ces systèmes, en plus de l’utilisation de la voix , la vidéo et les applications multi-utilisateurs, les utilisateurs peuvent collaborer en utlisant des applications prévues pour une seule personne. Il existe deux types d’architectures pour partager de telles applications: l’architecture centralisée et l’architecture repliquée. Ce papier décrit la conception et l’implémentation d’un système de partage d’applications basé sur l’architecture repliquée. Nous montrons quels types d’objets doivent être repliqués, la spécification de ces objets et les différentes approches pour implémenter les processus de replication. Ces concepts ont été utilisés pour implémenter JCE, un système de conférence multimédia et de partage d’applications Java.
