Design of BRT Three-dimensional Interchange Network Based on IPv4/IPv6 Hybrid Network

In this paper,by using IVI and NAT-PT technology,the pure IPv4 network and pure IPv6 network are realized interoperability.In order to achieve the fast communication between IPv4/IPv6 hybrid network and IPv6 networks,a BRT three-dimensional interchange system is proposed.The model is realized by building the BRT IPv6 channel in the dual-stack networks and IPv6 networks,to let IPv6 intercommunicate through the BRT special IPv6 channel.In the campus network,the model is finally designed that achieves and resolves the network communication problems as a result of IPv6 occupying IPv4 communication channel in dual-stack network to increase the network burden.
