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

6
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

CERNETExperiences 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

13
