      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
