IRTF Thing-to-Thing Research Group (T2TRG)

The IRTF Thing-to-Thing Research Group (T2TRG) investigates open research issues in turning a true “Internet of Things” into reality, an Internet where low-resource nodes (“things”, “constrained nodes”) can communicate among themselves and with the wider Internet, in order to partake in permissionless innovation. The focus of the T2TRG is on issues that touch opportunities for standardization in the IETF, i.e., it starts at the adaptation layer connecting devices to IP, and end at the application layer with architectures and APIs for communicating and making data and management functions (including security functions) available.

March 2016 T2TRG meeting in San Jose

The March 2016 T2TRG meeting will take place immediately before the IAB Workshop on IoT Semantic Interoperability in San Jose.

Join Hangout

The program for this meeting will have semantic interoperability as a natural focus (as well as a natural progression of much of the W3C collaboration so far); note that security also is/has semantics. We also are looking for some introductory talks in particular from North American players, and will share an afternoon with OCF (which used to be called OIC). We probably also want to spend some time progressing the plugREST and benchmark scenario ideas.

  • Date: Tue 2016-03-15 and Wed -16 (co-located with the IAB IOTSI workshop that follows on the next two days)
    • Time: Tue 10:00..18:00, Wed 09:00..18:00 PDT
      • Warning for participants from EU: This is Daylight Savings time in the US already then (PDT from Sun March 13), but not yet in the EU (EU DST starts Sun March 27). So this is one hour LESS in time difference (e.g., 8 hours to CET).
  • Location: San Jose, CA. Ericsson campus. 2795 Augustine Dr, Santa Clara, CA
    • There are three buildings in the Ericsson campus, but only one (building A) is operational at this time. Please come to building A lobby to pick up your badge. Parking is available around the building and in the parking garage behind the Building C.
    • Wed lunch and afternoon: Fremont Marriott Silicon Valley (with OCF)
  • Rooms: TBD (one large, additional breakout rooms available)
  • Registration link:
    • Registration deadline has passed — if you want to come unexpectedly, please contact the RG chairs so we can get you a badge!

(To be part of the IoTSI workshop following the RG meeting on Thursday/Friday, you had to submit a position paper by February 22 already.)

Focus of this meeting

Making best use of the colocation with the IoT Semantic Interoperability Workshop, aspects of application layer information exchange and the related security will be the main focus. This is actually a natural continuation of the two focus items we have had in previous meetings:

  • Using REST and beyond REST
  • IoT Security

We will also use the opportunity of a nearly co-located OICOCF meeting to spend an afternoon together with OCF with the objective of mutually understanding and stimulating our respective work.
