Internet in ChinaInternet users in China: from 6.8 Millions to 78 Millions within 6 months

What is the next generation Internet we needed
Internet have been an important infrastructure today and still deploy very fastMajor 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
Why is IPv6 needed?Much larger address space
IPv6 Addresses: 3.4X1038
Trust network: real IP address accessImproved routing
Route aggregation reduces the size of routing tablesSimplified 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 everywhereData, Voice, Audio and Video integration is a RealityRegional Registries apply a strict allocation control

CERNET: Experiences and Demands
Bandwidth always is not enough for Educated and Research NetworkCustom always needs new technology and app.Research and Education Network always tries new technology and applicationLambda Networking Nation Wide Backbone for Research and Education
Network Regional Network and Metropolitan Network Campus Network
Need mature technologies for the above networks
