The Internet of Things (IoT) is a buzzword around the Internet industry and the broader technology and innovation business. We are often asked what the IETF is doing in relation to IoT and in this short post for the IETF Rough Guide to IETF 97, I’d like to highlight some of the relevant sessions scheduled during the upcoming IETF 97 meeting in Seoul. First, though, I’d like to add a small advertisement for you to tune into the ISOC@IETF Briefing Panel on Tuesday, 15 November, during lunch on “The I in IoT: Implications for a Global Open Internet.” Registration to attend onsite is full, but you can watch the webcast live via this page.
Before talking about specific activities taking place in Seoul, I’d like to highlight a couple of recent IETF Journal articles that provide some background on IETF activity related to IoT. In “The Internet of Things Unchecked,” Dave Plonka provides a very timely call to take the threat posed by unmanaged IoT devices more seriously. Dave also includes some fascinating measurement results. “Low-Power Wide-Area Networks at the IETF” provides an excellent overview of the new breed of wireless technologies that are emerging to support a huge variety of IoT applications and introduces the new ipwave WG (more below). And finally, Samita Chakrabarti provides an update on the activity of the IPv6 over Networks of Resource-Constrained Nodes (6lo) Working Group that is developing specifications for running IPv6 over a range of wireless technologies suitable for IoT applications. More details of their meeting are provided below.
It’s also worth noting that the IAB is concerned about the risks posed by unmanaged IoT devices and recently held a workshop to discuss the challenges of providing software update mechanisms for constrained embedded devices. A draft report of the workshop proceedings is now available. The technical plenary in Seoul is also relevant and will include a moderated discussion of the recent Denial-of-Service attacks involving the use of compromised or misconfigured nodes and the architectural issues associated with the network being vulnerable to these attacks. There is some more detail here.
The Thing-to-Thing Research Group investigates open research issues in turning the IoT into reality. They will be meeting on Wednesday afternoon in Seoul to report out on various recent activities. The group will also be meeting jointly with the Information Centric Networking RG on Sunday November 13 in the morning (0900-1200), and there is a ‘Managing Networks of Things’ workshop taking place, also on Sunday, in the afternoon (1300-1700) at the Kensington Hotel Yoido.
The 6lo WG defines mechanisms to adapt IPv6 to a wide range of radio technologies, including “Bluetooth Low Energy” (RFC 7668), ITU-T G.9959 (as used in Z-Wave, RFC 7428), and the Digital Enhanced Cordless Telecommunications (DECT) Ultra Low Energy (ULE) cordless phone standard and the low-cost wired networking technology Master-Slave/Token-Passing (MS/TP) that is widely used over RS-485 in building automation. They will be meeting on Tuesday afternoon in Seoul.
The 6tisch WG was chartered in 2014 to enable IPv6 for the Time-Slotted Channel Hopping (TSCH) mode that was recently added to IEEE 802.15.4 networks. They are meeting on Thursday morning in Seoul.
Following on from a successful BoF meeting during IETF 96 in Berlin, the IPv6 over Low Power Wide-Area Networks (lpwan) WG has been chartered and will be meeting in Seoul for the first time. Typical LPWANs provide low-rate connectivity to vast numbers of battery-powered devices over distances that may span tens of miles, using license-exempt bands. This new WG will meet on Monday afternoon in Seoul.
Another relatively new WG is the IP Wireless Access in Vehicular Environments (ipwave) WG. This group’s primary deliverable is a specification for mechanisms to transmit IPv6 datagrams over IEEE 802.11-OCB mode. ipwave will meet on Wednesday afternoon in Seoul.
The core WG aims to extend the Web architecture to most constrained networks and embedded devices. This is one of the most active IoT working groups and they will be meeting twice in Seoul, on Wednesday afternoon and Friday morning.
Security for IoT is addressed in several WGs including the ace WG that is concerned with authenticated authorization mechanisms for accessing resources hosted on servers in constrained environments. ace will meet on Thursday afternoon.
Routing for IoT is tackled by the roll WG which focuses on routing protocols for constrained-node networks. Wednesday morning is the time for them to meet in Seoul.
Finally, in addition to the new protocols and other mechanisms developed by IETF working groups, IoT developers often benefit from additional guidance for efficient implementation techniques and other considerations. The Lightweight Implementation Guidance (lwig) WG is developing such documents and they will meet in Seoul on Thursday morning.
If you have an interest in how the IoT is developing and being standardised in the IETF, I hope to see you in person or online at some of these meetings during IETF 97.
