Large scale Internet backbone over native IPv6

CNGI-CERNET2 is the largest Internet backbone over native IPv6 around the world, which is designed and implemented on the worldwide innovative concept of establishing large scale native IPv6 network. The success of CNGI-CERNET2 provides the solutions to the problems including the topologies design, routing design, and so on, and provides the environment for technique trials and applications demonstrations on China 's next generation Internet.

Importance of constructing native IPv6 network

The large amount of IPv6 technology research activities and experiments have been carried out, and the results indicate that the cost of the maintenance and management for IPv4/IPv6 dual stack network is pretty high, and the network itself is not secure. Moreover, it seems that the future network development can not indeed break away from IPv4's influence and there will be least substantial development of operational IPv6 network, if IPv4/IPv6 dual stack network is going on. Whereas it is a big global challenge to establish large scale Internet backbone over native IPv6.

Providing solutions to key technical problems

The success of CNGI-CERNET2 provides a series of the solutions to key technical problems of network engineering technology over native IPv6, including the topologies, routing design, IP address assignment and DNS registration, network testing and measurement and integrative network management, and so on.

Multi-vendor IPv6 routers over large scale backbone

It was confirmed and implemented that the large scale Internet backbone over native IPv6 is built with multi-vendor IPv6 routers. This provides the solution to large scale inter-operability testing, and large scale inter-domain BGP routing, inter-operability and united network management between multi-vendor routers.

 

 

 

 

Network architecture based on real IPv6 source address validation

It is the newest technical solution around the world that network architecture is based on IPv6 source address validation, which consists of three levels including access, intra-domain and inter-domain. On the network architecture level, the pioneer technology provides safety guarantee for next generation Internet by IPv6 source address validation, and becomes the important technology foundation for trustable next generation Internet.

 

 

 

IPv4 over IPv6 transition t echnology

IPv4 over IPv6 transition technology is the newest concept of Internet technology around the world, and designed based on dynamic transition. This concept is oriented towards large scale distributed network, extends the core router protocol BGP, and submitted the application and obtained the ID from IANA. It provides a solution to the compatibility, manageability, expansibility, dependability and auto-configuration of the transition of IPv4 to IPv6.
