| Abstract: | Two problems, network layer multicast environment and conference manage, should be faced when constructing multicast based video conference on WAN. China Education and Research Network (CERNET) construct and realize the multicast based video conference system on CERNET backbone and make it the communication platform for CERNET nodes. The system running stably and reliably especially successfully applied during the period of 2003 SARS in China, is proved significant for deploying multicast-based video conference application in China. |
