  1. The Need for IPv6 in China Jianping Wu，Director of CERNET Jilong Wang 2002-10-28

  2. Content • Requirements for IPv6 In China • Service Providers’ Vision about IPv6 • R&D Efforts

  3. Resource distribution

  4. 16.13

  5. China Internet Estimation • Population in mainland China 1,200,000,000 • 1 IP per person • 72 class A IP addresses • 1 hour on line (28.8kbps) per person per day • 1.68T/s • 1 MB homepage per person • 1200TB

  6. Internet User trends Global Internet user Need IPv6 China user China need 72 /8 IP addresses if 1 IP/person

  7. Telephone user trends in China Need VoIP Need Mobile IP

  8. 40 2002 Millions 2001 2000 32 1999 1998 1997 1996 24 Pre-1996 16 8 0 JP CN KR AU TW HK IN TH MY SG Other APNIC IPv4 Address Distribution

  9. Requirements for IPv6 • Scalability Challenges • Size（Address Space） • Performance（Routing） • Manageability Challenges • Security • QoS • Mobility • Application Promotions

  10. Special Opportunities for IPv6 in China • Development of Broadband • Education Application • Relative Small IPv4 Coverage（some easy to change or adapt new） • Encouragement From Government • Olympics 2008

  11. Different Voice • How many IPv4 addresses can China get？ • Will IPv4 NAT work for China? • Should China implement IPv6? • Who pay for IPv6 transition? • Will China benefit from new features of IPv6 ? • What are the killer applications of IPv6 ？

  12. Service Providers • China Telecom • CERNET（Noncommercial） • China Mobile • China Netcom • China Unicom • China Railway • China Satellite • CSTNET （Noncommercial）

  13. China TeleCom

  14. China MobileCom

  15. Policies • Follow the development • Research on business model • Transition from IPv4 to IPv6 • Key Tech. • Terminals • Test • Tech • Service • Operation

  16. ? China Netcom • A Large-Scale IPv4 Network Built • Concerned with the benefits of IPv6 • IPv4 still can manage to work • How to use existing IPv4 equips • Cost for Transition • Maturity of IPv6 • Hence and egg Problem • No operational network to support app • No killer app to promote Network deployment

  19. CERNET IPv6

  20. Services • IP allocation by CerNIC • Tunnel broker • Common applications • WWW • DNS • FTP

  21. Future • Developing Native IPv6 Network • Parallel Develop with IPv4 Internet • Merge Transparently with IPv4 on service and application level • Maybe First Success in Some Special Area • Success Depends on the Speed of Commercialization

  22. IPv6 Efforts • 1998, CERNET-IPv6 Test-bed • 1999, IPv6 demo system funded by MST 863 • 1999, CERNET-Nokia joint IPv6 project • 2000, NSFCNET funded by NSFC • 2001, IPv6 Router funded by MST 863 • 2001, IPv6 MAN demo system funded by CAS • 2002, IPv6-CJ funded by Chinese government and Japanese government

  23. IPv6-CJ Test-bed

  24. CJ-IPv6 Joint Project • Supported by Chinese and Japanese Government • Project Contents • More than 20 Org. and Companies • Test bed: IPv6, 2.5Gbps connect BJ, SH and GZ • Connect Local IPv6 Testbed • Backbone IPv6 Router from Japanese Companies and Another • Link to Japanese IPv6 Networks at 45Mbps • Systems: IPv6 Router/Switch, Host and Terminals • WLAN Mobile System and IPv6 Security • Applications: IPv4 to IPv6, IPv6 Applications • Standard:
