The Internet Architecture Board responded to the United States National Telecommunications and Information Administration Request for Comments, The Benefits, Challenges, and Potential Roles for the Government in Fostering the Advancement of the Internet of Things. In this document IAB summarise some of the main answers provided to NTIA. The IAB draw attention to a document published by IAB on March 2015, entitled "Architectural Considerations in Smart Object Networking" (RFC 7452). That document includes a classification of four communication patterns common in Internet of Things today, namely Device-to-Device, Device-to-Cloud, Device-to-Gateway, and Back-End Data Sharing. IAB believes such a classification, among others, should be used to improve the precision of technical and policy discussions. Also this document discusses a number of privacy concerns around IoT, and provides a number of IAB recommendations on this topic. A significant problem that the IAB observed was the proliferation of competing standards for data models of various categories of IoT devices being done by many different organizations.
