Internet users in China Source: CNNIC, Jan. 2005

What is the next generation Internet we needed • Internet have been an important infrastructure today and still deploy very fast • Major characteristics of next generation Internet: – – – Large scale network: IPv 6 address End to end high performance Secure and trustworthy network Qo. S control network Mobility • There is not unify definition for next generation Internet but IPv 6 should be an important part of NGI

Why is IPv 6 needed? • Much larger address space –IPv 6 Addresses: 3. 4 X 1038 • Trustworthy network: real IP address access • Improved routing –Route aggregation reduces the size of routing tables –Simplified header reduces router processing loads • Enhanced security and Qo. S –Mandatory IPsec support all fully IPv 6 compliant devices • Improved support for mobile IP and mobile computing devices –IP is everywhere –Data, Voice, Audio and Video integration is a Reality –Regional Registries apply a strict allocation control

One year after the launch of IPv 6 service Global IPv 6 Service Launch Event January 15 2004

CERNET Interconnections

CERNET：Experiences and Demands • Bandwidth always is not enough for Educated and Research Network • Custom always needs new technology and app. • Research and Education Network always tries new technology and application • Lambda Networking – Nation Wide Backbone for Research and Education Network – Regional Network and Metropolitan Network – Campus Network • Need mature technologies for the above networks

Next Generation Internet and IPv 6 Activities in China • IPv 6 Test bed and 6 Bone in 1998 • NSFCNET: 2000，First IPv 6 network in China • MOU with UCAID: CERNET on March 2000, NSFCNET and CSTNET on May 2000 • Peer Connection Agreement with Abilene: CERNET on March 2000 • International Connections – 45 M to STAR TAP； 45 M to APAN（Japan），45 M to Korea ； 45 M to Janet • 2003，CJ-IPv 6， CNGI Project, CNGI-CERNET 2 • 2004, CNGI/CERNET 2 opened service, over 100 Universities connected

NGI and IPv 6 in China

APAN and APAN-6 IX

CNGI Project • Initiated from 2002 and approved by in 2003 • Leaded by National Reform and Development Committee, 170 M USD • Joint with MST, MOE，CAS，MII，NSFC，CAE, … • Main contents – CNGI Backbone: nation wide, 30 Giga. POPs and 300 campus networks, international links to academic networks – Research on Network technology and applications – Delivery the result to information industry • All NSPs joined in this project – CERNET, China telecom，Unicom，Netcom/CSTNET， China Mobile, Railcom
