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
