If you haven’t seen RFC 5856 to 5858: This is a miniseries of documents where we have done the analog thing for the ROHC Robust Header Compression scheme that is now being proposed for the SCHC Static Context Header Compression scheme. The actual allocation of an Internet Protocol Number to ROHC is in Section 6 of RFC 5858: https://www.rfc-editor.org/rfc/rfc5858.html#section-6 IANA has allocated the value 142 to "ROHC" within the "Protocol Numbers" registry [PROTOCOL]. This value will be used to indicate that the next-level protocol header is a ROHC header. Some forms of ROHC headers contain a next header field, but mostly that field is compressed away as it is redundant between packets in a flow. Bob’s document is doing the equivalent to RFC 5858, now for SCHC. Once there is a WG adoption call, I’ll express that I am very much in favor of this work going forward. (As I have said before, I’d also like to see the equivalent IKE/IPsec support that RFC 5856 and RFC 5857 provide for SCHC as well. But this can be done on different timescales.)
