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, and it 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 and UDP headers,
   this document applies SCHC to CoAP headers.  The CoAP header
   structure differs from that of IPv6 and UDP headers, since CoAP uses
   a flexible header with a variable number of options that are in turn
   of variable length.  The CoAP message format is asymmetric, i.e.,
   request messages have a header format different from that of response
   messages.  This specification gives guidance on applying SCHC to
   flexible headers and on leveraging the message format asymmetry for
   defining more efficient compression Rules.  This document replaces
   and obsoletes RFC 8824.
