The impact of scaling on a multimedia connection architecture

As the last two meetings of the Internet Engineering Task Force (IETF) have shown, Internet teleconferencing has arrived. Packet audio and video have now been multicast to approximately 170 different hosts in 10 countries, and for the November 1992 meeting the number of remote participants is likely to be substantially larger. Yet the network infrastructure to support wide scale packet teleconferencing is not in place.
