I'm not sure that draft-ietf-opsawg-pcaplinktype Proposes a Standard. draft-ietf-opsawg-pcap and draft-ietf-opsawg-pcapng could be viewed as proposing that two already-existing capture file formats, in significant use, be considered standards of some sort, at least to the extent that an RFC documents them. Both of those file formats have fields whose values correspond to linktypes, with the set of linktypes, and the numerical values corresponding to each linktype, being the same for the field in pcap (the per-file linktype) and pcapng (the per-interface linktype). draft-ietf-opsawg-pcaplinktype proposes a large number of linktypes to be assigned particular numerical values, so I'm not sure it proposes *a* standard, any more than, say, RFC 790's "ASSIGNED INTERNET PROTOCOL NUMBERS" section proposes *a* standard. That might be the best analogy here: draft-ietf-opsawg-pcap defines a file format, with a "LinkType and additional information" field in the file header, the low-order 16 bits of which contain a "LinkType", just as RFC 791 defines a protocol, with the protocol header containing a "Protocol" field that contains a protocol number; draft-ietf-opsawg-pcapng defines a file format, with a "LinkType" field in every Interface Description Block in the file that contains a "LinkType", just as RFC 8200 defines a protocol, with the protocol header and extension headers containing a "Next Header" field that contains a protocol number; draft-ietf-opsawg-pcaplinktype defines a bunch of values for "LinkTypes", just as RFC 790's "ASSIGNED INTERNET PROTOCOL NUMBERS" section defines several protocol numbers. The intent is to have a registry for "LinkTypes", just as there's a registry for protocol numbers; neither registry's contents are fully specified by a single document, as additional values have been and, if a registry for "LinkTypes" is established, will in the future be added. _______________________________________________ OPSAWG mailing list OPSAWG@ietf.org https://www.ietf.org/mailman/listinfo/opsawg
