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 -- 2001250/35, 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.

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

We Believe
Next generation of the network engineers and
scientists of China will come from todays net
players.
Where are they today?
