Abstract
Multiple users participate in a conference while taking maximum advantage of hardware and bandwidth capabilities of each participant. Each user's system makes known to a directory service its hardware sending and receiving capabilities. The directory service makes this information available to other users who may then wish to join a conference with the user. An initiating user sends invitations via the directory service to the remote users. Each user that accepts an invitation transmits its network address to the initiating user, who then establishes a peer-to-peer connection with each of the remote users. Each participant system exchanges information about hardware capabilities and bandwidth, and a conference manager determines a best model for connecting each of the participants. Depending on the hardware and bandwidth capabilities of the participants, the manager chooses from a duplicate streams model, a multicast model, and a host-among-peers model for connecting the participants.
