Abstract

China Education and Research Network (CERNET) is the first Native Multicast backbone in China. It now provides multicast service on all 10 GigaPops and is enlarging service to its 28 Pops. PIM-SM/MBGP/MSDP routing protocols with Anycast RPs are adopted to build multicast distribution tree and exchange SAs (source active) in intra-domain and inter-domains. Several security polices are taken for multicast routing. CERNET multicast network has national multicast ISP peer with NSFCNET and international multicast ISP peers with APAN In JAPAN and STARTAP in U.S.A. This Paper addresses the key technologies for design and implementation of CERNET multicast network. IP/Multicast based Videoconference services developed on CERNET are also introduced in this paper.
