At present, the internet has developed into the next-generation internet time, some organizations have proposed to integrate the internet architecture about the internet of things (IOT), but as for the continuous development of the next-generation internet and wireless network, there has no systematic research on heterogeneous network between the next-generation internet and the IOT. Thus for the IOT and the next-generation network’s development issue, firstly divide the core network development into four stages, design to the partial newly-build IPv6 network mode, dual-stack core network mode, IPv6 core network mode and IPv6-only network mode. Propose the architecture plan including sensor network from non-IP to IP mode, IOT access sub-network from IPv4 to IPv6, the core network from IPv4 to IPv6 integration development architecture scheme, and finally design the next-generation internet and IOT network integration comprehensive architecture mode, resolve the network constant change and the integration architecture problems under different application contexts.
