Technical Summary

RFC8724 has specified a generic framework for Static Context Header Compression and fragmentation (SCHC), designed with Low Power Wide Area Networks (LPWAN) in mind.
LoRaWAN(R) is one such LPWAN technology.
This document describes parameters and modes of operation for efficiently using RFC8724 over the LoraWAN networks.

Working Group Summary

There was no particular controversy or rough consensus to be noted.
The authors are affiliated with two companies that have a strong involvement both in the IETF LPWAN WG and in the LoRa Alliance.
Feedback and design considerations were received from other companies primarily involved in the LoRa Alliance.
Information has been delivered both ways between the two SDOs, so we beleive the interests of the LoRa Alliance are well addressed by this document.
There were technical discussions and design iterations regarding features allowing RFC8724 to efficiently operate over quasi-bidirectional links, which were constructive and professional.

Document Quality

   Are there existing implementations of the protocol?  Have a 
   significant number of vendors indicated their plan to
   implement the specification?  Are there any reviewers that
   merit special mention as having done a thorough review,
   e.g., one that resulted in important changes or a
   conclusion that the document had no substantive issues?  If
   there was a MIB Doctor, Media Type, or other Expert Review,
   what was its course (briefly)?  In the case of a Media Type
   Review, on what date was the request posted?

Personnel

The document shepherd is Dominique Barthel.
The Responsible Area Director is Éric Vyncke. 

IESG Note

AD has checked with authors whether Lora Alliance has been consulted and is happy with this document.
