  1. China Next Generation Internet CNGI Project Jianping Wu Sept. 25, 2003

  2. Background • Internet development in China • 70 Millions in June 2003 • Important information infrastructures • No enough IP addresses • Applications need Next Generation Internet • Scale, Fast, QOS，Security, Mobile • Internet2/GEANT/APAN/GTRN activities • Opportunities for information industry in China

  3. Next Generation Internet in China

  4. GEANT （欧洲） Abilene （美国） STARTAP 45Mbps 10 Gbps 10Mbps DRAGONTAP APAN （亚太地区） 2.5Gbps 10Mbps CERNET CSTNET NSFCNET Dragon TAP in China

  5. CNGI project • Initiated from 2002 and approved by in 2003 • Leaded by National Reform and Development Committee • Joint with MST, MOE，CAS，MII，NSFC，CAE,… • Main contents • CNGI Backbone: nation wide,30 GigaPOPs and 300 campus networks,international links • Network technology and applications • Delivery to information industry • All NSPs will joint this project • CERNET, China telecom，Unicom，Netcom/CSTNET，China Mobile, Rail com

  6. CNGI Backbone Goals • Network Architecture • Backbone：Native IPv6；IPv6 over DWDM • User Networks：Native IPv6 Application；v4 over v6；High Performance NAT • Addresses：Backbone/32；User/48 • DNS：Distributed Native IPv6 DNS • Routing Policy: Complexity enough • Regional Network and User Network • Interconnection in China and to outside of China ：One GigaPoP in Beijing and Anothers • Network operation and management • Network and Information Security • Network Applications
