  1. CNGI: China Next Generation Internet Jianping WU CERNET and Tsinghua Univ. Nov. 30, 2004

  2. Contents • Internet development in China • Research Network in China • IPv6 and its development in China • CNGI Project • CERNET2 and its progress

  3. Internet development in China • 10 years history from 1994－2004 • Internet users in China: from 78 Millions to 87 Millions within 6 months • IP Addresses: >32M（1A+233B+146C） • Backbone：2.5-10G DWDM+Router • International links：>20G • Exchange Points：> 30G（BJ，SH，GZ） • Last Miles • Ethernet，WLAN，ADSL，Cable Modem，CDMA，GPRS，ISDN，Dial-up，

  4. Research Networks in China • CERNET: China Education and Research Network • 1994, Managed by MOE, Nation wide backbone • 1300+ Universities and institutes, over 15 Millions users • CSTNET: China Science and Technology Network • 1994, Managed by CAS, Nation wide connections • 100+ institutes, Users over 0.8 Millions • NSFCNET: • 2000, Supported by NSFC, 6 nodes in Beijing city

  7. CERNET Interconnections

  8. Some problems and challenging in Internet deployment • Scale problem: IPv4 address limit, IPv6 needed • NAT is bad technology, we need more and more IP addresses for mobile, IPTV, home electronic devices • End to end performance • At least 100Mbps for end to end • QOS and multicast • IPTV, high quality video conference • Security • Authentication, identification and authorization • Mobile communication: anytime and every where

  9. 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: IPv6 address • End to end high performance • Security and trust network • QOS control network • Mobile • There is not unify definition for next generation Internet but IPv6 should be an important part of NGI

  10. Why is IPv6 needed? • Much larger address space • IPv6 Addresses: 3.4X1038 • Trust network: real IP address access • Improved routing • Route aggregation reduces the size of routing tables • Simplified header reduces router processing loads • Enhanced security and QoS • Mandatory IPsec support all fully IPv6 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

  11. Next Generation Internet and IPv6 Activities in China • IPv6 Test bed and 6 Bone in 1998 • NSFCNET: 2000，First IPv6 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 • 155M to STAR TAP；45M to APAN（Japan），155M to Korea；45M to Janet • 2003，CJ-IPv6， • CNGI Project, CNGI-CERNET2

  12. NGI and IPv6 in China

  13. Global IPv6 Service Launch EventJanuary 15 2004

  14. China Next Generation Internet Development Planning • 2002－2005 • CNGI: China Next Generation Internet • Key technologies and applications • Delivery CNGI technologies to industry • 2006－2010 • Largest Ipv6 networks in the world • Contribute something to NGI: RFC’s • NGI application development • As advanced foundations for Chinese innovation

  15. CNGI Project • Initiated from 2002 • Approved by Chinese State Department in 2003 • Leaded by National Reform and Development Committee, and Joint with MOST, MOE，CAS，MII，NSFC，CAE • 170M USD • 75M USD for backbone • 95M USD for technology dev. and applications • All NSP’s will joint this project • CERNET, China telecom，Unicom，Netcom/CSTNET，China Mobile, Railcom

  16. Main Contents of CNGI • CNGI Backbone • 6 nation wide backbone and 30 GigaPOPs • 300 campus networks • International links • Network technology and applications • Development and experimentation on network technology • Middleware • Applications • Delivery to information industry • Major software and hardware • Application
