Abstract
Mechanisms for efficient transmission management are provided for multiparty, multimedia communications by constructing a logical ring structure from logical point-to-point connections between multiple nodes participating in a communication. Data and control information are unbundled in the communication by providing several different higher level protocols or applications, called "user entities," at each node and enabling uninhibited data transfer between corresponding user entities of the different nodes via virtual rings built on top of the logical ring. A mechanism preferably is provided for a user entity to selectively accept or reject a packet on the basis of the importance of the information contained in the packet.
