Abstract
As more applications of video and audio to be used more researches QoS measurement of multicast are being done nowadays. Even more experiments which are done at the international research network are more important than before. In this paper we use overlay multicast technology to construct a test -bed with overlay multicast r elay (OMR) over international research network. We do multicast QoS experiments in the test -bed with international research network and make analysis and comparison. Through these research works, we get different kind of performance valuation of multicast in international research network. We propose QoS measurement method of multicast video service in the international research network.
