BackgroundLike AccessGrid, Conference XP is an open-source project by Microsoft to centralize conference point (voice/video conference & etc) for both multicast/unicast network. For every conference held, there is a central host, called the "venue". Its role is to update all clients with necessary network information such as the multicast address and the port number of the conference. With these informations, clients can then operate in a peer-to-peer manner, sending voice/video traffic directly to each other. ViSLAB hosts a Conference XP venue server at http://confxp.vislab.usyd.edu.au/venueservice. If your institution wishes to have its own virtual venue, please contact ViSLAB.
