Episode 23

Timeslotted Channel Hopping (TSCH), via IEEE 802.15.4e, is an emerging standard in industrial automation and process control (via Wireless HART and ISA 100.11a) that defines a communication schedule between neighbor nodes in Low-power and Lossy Networks (LLNs). In an effort to bridge the worlds of operational technology (OT) with information technology (IT), the 6TSCH working group has been established to define how to use IPv6 over the 15.4e.

The IETF 6TiSCH working group, along with the other layers as described by 6LoWPAN, ROLL and the CoRE IETF working groups define a complete IP protocol stack to converge OT with IT by binding of IPv6 related open standards with 15.4e TSCH deterministic MAC layers.

Watch this video to hear Xavi Villajosana explain how 15.4e operates and what’s still missing in the complete OT/IT stack.
