Technical Summary This document describes the minimal set of rules to run IPv6 over an IEEE 802.15.4 Timeslotted Channel Hopping (TSCH) network, including the operation of the RPL routing protocol and the procedures to forward packets using a static schedule of shared time slots in a slotted-aloha fashion. Working Group Summary Like for the other 6TiSCH documents, it took a long time and great care to achieve consensus on the security piece. Considering the complexity (and issues) in IEEE802.15.4-2011, the group decided to provide reference examples of how the MAC can be set in order to achieve interoperability. Though MAC level messages are widely discussed and many references to undated IEEE802.15.4 specs are made, and apart from a particular problem with the IEEE802.15.4e spec that has to be treated in section 4, the example section 11 is the only place in the document that has dated IEEE references. The rest of the document uses undated references so it is preserved through future backward compatible updates of IEEE802.15.4. The draft was the subject to an ETSI PlugTest and the Hackathon in Prague. 4 different implementation on multiple platforms and OSes were tested. Document Quality There are 3 different open source implementations, Contiki, TinyOS and Open WSN. Multiple derivatives of Open WSN are also available and were confronted at the ETSI PlugTest in Prague. There are also shipping products in the AMI/AMR domain (Wi-NAN) that operate in pre-standard variations of this work and we expect them to move to the standard version at some point of time. There were also discussions on how IEEE specs should be referenced; the authors followed the best practices obtained from multiple parties, including the RFC editor and the IEEE-IETF coordination, of using undated references whenever possible.
