This document updates the Static Context Header Compression (SCHC)
and fragmentation protocol (RFC 8724) and the corresponding YANG
module (RFC 9363). It defines a SCHC Compound Acknowledgement (ACK)
message format and procedure, which are intended to reduce the number
of response transmissions (i.e., SCHC ACKs) in the ACK-on-Error Mode,
by accumulating bitmaps of several windows in a single SCHC message
(i.e., the SCHC Compound ACK).
Both the message format and procedure are generic, so they can be
used, for instance, by any of the four Low-Power Wide Area Network
(LPWAN) technologies defined in RFC 8376, which are Sigfox, Long
Range Wide Area Network (LoRaWAN), Narrowband Internet of Things
(NB-IoT), and IEEE 802.15.4w.
This document is a product of the IPv6 over Low Power Wide-Area Networks
Working Group of the IETF.
This is now a Proposed Standard.
