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