[core] Fwd: New Version Notification for draft-tiloca-schc-8824-update-02.txt

[Marco Tiloca <[e-mail]>]

Hello SCHC,

(also CCing CoRE for information)

We have recently submitted a new version of 
draft-tiloca-schc-8824-update [1].

Following-up on previous discussions and according to the outcome from 
IETF 117 [2], we have made a major restructuring of the draft, which is 
now written as a bis document intended to obsolete RFC 8824.

In the process, we also took the opportunity to make an overall 
editorial revision and improve readability. Like we were hoping for, the 
document is now self-contained and including all the information about 
SCHC compression of CoAP headers in one place.

Comments and feedback are very welcome!

Best,
/Marco

Abstract:

This document defines how to compress Constrained Application
Protocol (CoAP) headers using the Static Context Header Compression
and fragmentation (SCHC) framework. SCHC defines a header
compression mechanism adapted for Constrained Devices. SCHC uses a
static description of the header to reduce the header's redundancy
and size. While RFC 8724 describes the SCHC compression and
fragmentation framework, and its application for IPv6/UDP headers,
this document applies SCHC to CoAP headers. The CoAP header
structure differs from IPv6 and UDP, since CoAP uses a flexible
header with a variable number of options, themselves of variable
length. The CoAP message format is asymmetric: the request messages
have a header format different from the format in the response
messages. This specification gives guidance on applying SCHC to
flexible headers and how to leverage the asymmetry for more efficient
compression Rules. This document replaces and obsoletes RFC 8824.
