Group Coordination Protocol for Networked Multimedia Systems

Able to support long-distance, many-to-many group collaboration Shared access to resources by many users in real-time can be mitigated in a fair, distributed control process established by a network protocol Permits more efficient conference control over a shared control tree with concurrent reliable multicast Able to support selective, secure, and anonymous collaboration at real-time Extends concurrency control and mutual exclusion technology to general multimedia semantics and direct user-to-user interaction, thereby allowing any collaborative application of the method from local to internet-wide scope

Teleconferencing systems Distributed interactive simulations Distance learning seminars Sharing resources in a virtual workspace

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.
