IPv6 Gets Ready for the Smart Grid and the Internet of Things
They discussed how as devices proliferate into diverse and special-purpose networks, the enhanced address space, routing and security features of IPv6 will be required for universal connectivity. In particular they talked about how this will play out in Smart Utility Network's in the coming years with advancement in 6LoWPAN's and the general move towards everything communicating over IP.
They also mentioned that the IETF Core working group "is providing a framework to enable RESTful web services to work efficiently on 6LoWPANs, and the IETF ROLL working group is defining route protocols for use in mesh-based LLNs. Meanwhile, the IEEE 802.15 working group is defining layer 1 and layer 2 standards applicable to smart utility networks (SUNs) and 6LoWPANs."
IETF Constrained RESTful Environments (CORE) working group is also "developing an architecture and application protocol (CoAP) to extend the benefits of RESTful application development to constrained environments"
They conclude with "IPv6 is indeed poised to emerge from its 13-year hibernation as the networking technology of choice for the Smart Grid, SUNS and the Internet of Things"
