The IESG has approved the following document: - 'SCHC Compound ACK' (draft-ietf-lpwan-schc-compound-ack-15.txt) as Proposed Standard This document is the product of the IPv6 over Low Power Wide-Area Networks Working Group. The IESG contact persons are Erik Kline and Éric Vyncke. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-lpwan-schc-compound-ack/ Technical Summary The present document updates the SCHC (Static Context Header Compression and fragmentation) protocol RFC8724. It defines a SCHC Compound 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 message format and procedure are generic, so they can be used, for instance, by any of the four Low Power Wide Area Networks (LPWANs) technologies defined in RFC8376, being Sigfox, LoRaWAN, NB- IoT and IEEE 802.15.4w. Working Group Summary There was a broad consensus in the WG about the document. All remarks and potential issues were treated with respect, discussed openly and addressed. No controversies, no rough points. Document Quality There were two last call directorate reviews (SEC & OPS) and the comments were addressed by the authors.
