Ballot Text

Technical Summary

   This document defines the 6top Protocol (6P), which enables
   distributed scheduling in 6TiSCH networks.  6P allows neighbor nodes
   to add/delete TSCH cells to one another.  6P is part of the 6TiSCH
   Operation Sublayer (6top), the next higher layer to the IEEE Std
   802.15.4 TSCH medium access control layer.  The 6P layer is formed by
   the 6top Protocol defined in this document and 6top Scheduling
   Function(s).  A 6top Scheduling Function (SF) decides when to add/
   delete cells, and triggers 6P Transactions.  This document lists the
   requirements for an SF, but leaves the definition of SFs out of
   scope.

Working Group Summary


This document was not controversial. The design was complex due to the need to save exchanges and yet provide transactional outcomes.
The next generation of the work may be done at IEEE, e.g. within IEEE Std. 802.12

Document Quality

This specification was implemented in openWSN and contiki.
It was interop tested at the 6TiSCH F-interop in Prague:
http://www.etsi.org/news-events/events/1197-6tisch-interop-prague-2017
Return from experimentation is implemented in the draft

Personnel

Pascal Thubert is the Document Shepherd. Suresh Krishnan is the Responsible Area Director.
