Hello Joel:
SCHC could be used to compress IP option headers and the residue be stored in a
SCHC option, which a next header points at uncompressed transport (e.g.,
encrypted, uncompressible).
Additionally, finding the SCHC context may require metadata that could also be
found in a SCHC option. Over one hop in LPWAN that is all implicit but over IP
it might not be.
SCHC is layered depending on which endpoint talks to which. E.g., you compress
a tunnel with inner that is already SCHC-compressed, you do security, etc...
So you could have SCHC options one after the other. We have not defined the
option yet, LPWAN is discussing recharter to cover SCHC applied beyond LPWANs.
But since we're at it, let's do both in one RFC.
Note that we'll also need a value for IPv6-Compression-Protocol Types, see
https://www.ietf.org/archive/id/draft-thubert-intarea-schc-over-ppp-03.html#name-iana-considerations.
I cannot find this IANA registry. Can someone please provide the URL.
And this is why I have been instructed, and have adhered to, including
IANA URLs as informative references in my drafts.
Like in draft-moskowitz-intarea-schc-ip-protocol-number!
