  1. IPv6 Deployment and Developmentin CERNET

  2. CERNET • Founded in 1995 • 155Mbps+ backbone • 700+ education and research organizations over 125 cities in the Mainland of China • Connecting 3 million users • Its National Center is located in Tsinghua U.

  3. CERNET IPv6 Activities • Testbed and Deployment • Research and Development Projects • Publication

  4. CERNET IPv6 Testbed • Since April 1998 • First tunnel to Merit • First BGP peer to Sprint • p-TLA 3ffe:3200::/24 since November 1998 • Connecting CERNET all backbone site and about 20 universities 2 parts: official and student

  5. CERNET IPv6 Testbed • 2 Parts Topology • Official part • follows CERNET IPv4 operation rules • Student part • stimulates students participation • expands experimental activities • Classroom for CERNET IPv6 Network CERNET IPv6 Backbone -- 2001:250::/35, the only IPv6 SubTLA in China, assigned by APNIC in April 2000; 6 months experience in the testbed is required for getting blocks in the CERNET IPv6 networks.

  6. CERNET IPv6 2001 • A native network in Beijing • A tunneled backbone nation-wide • Tunnel broker services for students

  7. CERNET IPv6 Projects • National Project • IPv6 Demo System • Testbed design and deployment • Address allocation policy • Demo network running IPv6-enabled applications • Transition demo -- an IPv6/v4 web proxy

  8. CERNET IPv6 Projects • CERNET-Nokia Joint Project • IP650 nation-wide IPv6 networking • Key technology research • Example: Tunnel Broker Implementation and Improvement • See http://www.internet6.com.cn/ for details

  9. CERNET IPv6 Publications • Chinese version homepages • - http://www.ipv6.net.edu.cn/- http://ngtrans.6test.edu.cn/- http://www.njnet6.edu.cn/- http://v6rt.ecn.6test.edu.cn/ • Chinese-original IPv6 Book • IPv6 Principles and Practices

  10. Future: IPv6 University Networks • The only solution China: 74 A-class blocks needed if each one holds an IPv4 address! THU: 20,000 student net-players who are using Internet in their dormitory! • Tunnel Broker driven transition - A mandatory IPv6 address for each student - Mobility support

  11. We Believe Next generation of the network engineers and scientists of China will come from today’s net players. Where are they today? Picture is copied from http://www.tsinghua.edu.cn/
