Collaborative Multimedia Applications (CMA) allow users to share information and efforts in real-time and are becoming increasingly popular for group tele collaboration across many networks. However, many fundamental coordination problems in current multicasting systems limit the widespread sharing of virtual workspaces. The resulting consequences, such as flawed telepresence, mutual awareness coordination problems, speech initiation conflicts, and diminished interaction, can be remedied by an effective mediation protocol.
Scientists at the University of California have developed a novel method of orchestrating the interaction and collaboration of groups working together on a computer network in real time. By using a Hierarchical Group Coordination Protocol (HGCP) embedded with a reliable hierarchical multicast, this method can support large groups on the internet instead of a few users within a local-area network.
