IP/multicast video conferencing for distance learning
Xuan Zhang · Journal of Tsinghua University(Science and Technology) · 2003
IPbased Video Conferencing (VC) will be widely used in the next generation Internet. Comparison of the two VC technologies based on H.323 and IP/Multicast shows that IP/Multicast technology has better reliability and efficiency. The IP/multicast remotelecture system can be synthesized with multicast and unicast communications to remotely manage lectures. Tests of the system on NSFCNET, an advanced Chinese network testbed, and the CERNET backbone shows that the IP/multicast based remotelecture system works well on the advanced Chinese networks. The IP/multicastbased remotelecture will be widely applied in distance learning.Key words: video conference; IP/multicast; distance learning; internet application
