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
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 access
Improved routing
Route
aggregation reduces the size of routing
tables
Simplified header reduces router processing
loads
Enhanced security and QoS
Mandatory
devices
IPsec support all fully IPv6 compliant
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
Explosion of New Internet

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
