The majority of todays Internet applications rely on point-to-point transmission. In recent years, however, multicast transmission has become the foundation for such applications as multiparty video conferencing, distributed interactive simulations, and collaborative systems. The authors describe a novel protocol to coordinate multipoint groupwork in the IP-multicast framework. The protocol supports Internet-wide coordination for large and highly interactive groupwork, relying on transmission of coordination directives between group members across a shared end-to-end multicast tree. They also describe how addressing extensions to IP multicast can be put to use for their multisite coordination mechanism.
