Dear 6lo WG,
(CC'ing the SCHC WG.)
Please find below the main pointers to our last revision of the
"Transmission of SCHC-compressed packets over IEEE 802.15.4 networks" draft
(a.k.a. "the SCHC-Lo draft").
Main changes:
o Addressed the comments from Esko's comprehensive review (many thanks,
Esko!):
- Modified PRO to allow routers read and set ECN bits from the
IPv6 header
- Improved the specification of the PRO Address Residue Length
field
- Clarified: hybrid approaches (mesh-under, route over), SCHC
C/D for messages from/to 6LRs/6LBRs
- Removed a note on the term '6LN' for consistent use throughout
the document
- Several editorial improvements
- Reduced figures X-axis sizes
o Aligned the terminology with terms considered stable in
draft-ietf-schc-architecture-05:
- SCHC Control Header, SCHC Data, SCHC Datagram.
Comments are very much welcome!
Cheers,
Carles and Ana

Title: Transmission of SCHC-compressed packets over IEEE 802.15.4
networks

Abstract:
A framework called Static Context Header Compression and
fragmentation (SCHC) has been designed with the primary goal of
supporting IPv6 over Low Power Wide Area Network (LPWAN) technologies
[RFC8724]. One of the SCHC components is a header compression
mechanism. If used properly, SCHC header compression allows a
greater compression ratio than that achievable with traditional
6LoWPAN header compression [RFC6282]. For this reason, it may make
sense to use SCHC header compression in some 6LoWPAN environments,
including IEEE 802.15.4 networks. This document specifies how a
SCHC-compressed packet can be carried over IEEE 802.15.4 networks.
The document also enables the transmission of SCHC-compressed UDP/
CoAP headers over 6LoWPAN-compressed IPv6 packets.
