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
Secure and trustworthy network
QoS control network
Mobility
• There is not unify definition for next generation
Internet but IPv6 should be an important part of
NGI
Why is IPv6 needed?
• Much larger address space
–IPv6 Addresses: 3.4X1038
• 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 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
One year after the launch of IPv6 service
Global IPv6 Service Launch Event
January 15 2004

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
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
– 45M to STAR TAP；45M to APAN（Japan），45M to Korea；
45M to Janet
• 2003，CJ-IPv6， CNGI Project, CNGI-CERNET2
• 2004, CNGI/CERNET2 opened service, over 100
