This paper probes into a set of audio/video conference system based on Microsoft Exchange 2000. It introduces the principle and network structure of the system, and discusses how to realize interdomain multicast of the system. The main function of the system is realized by software and hardware. Accomplishment of the system is done at a lower cost over Internet, so it has effect in popularizing audio/video operation and extending function over Internet.
