Although H.320 is one of the most popular ITU-T standard for video conference systems, H.323 is receiving wide acceptance in the Internet society. In this paper, we study the problem of transporting video conference traffic to and from the Internet. Some characteristics of the problem are as follows. For example, H.323 video stream is VBR while H.320 video stream is CBR; H.323 is byte-oriented while H.320 is bit- oriented; audio and video packets are transmitted independently in H.323 while they are multiplexed together in H.320; the probability of packet loss in an H.323 network is much higher than in an H.320 ISDN circuit switching network. In this paper, we present our designs and some preliminary experimental results in dealing with these issues.
