Abstract:
   This draft defines how to compress the Constrained Application
   Protocol (CoAP) using the Static Context Header Compression (SCHC).
   SCHC is 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 for 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 protocol messages format is asymmetric:
   the request messages have a header format different from the one 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.
