Ralph, Under RFC 2780, IPv6 hop-by-hop option numbers are granted either with an approved IETF document, or an IESG review. IANA made the request to IESG under the last option in RFC 2780, and the IESG did its reviewing within the IESG. We followed the BCP process. Note that we do not even have clear permission to provide the document we reviewed to the IETF. IANA requests from other standards bodies where there is not an i-d do not presume an available document. There were several cross-area questions to the review: - IPSec, transport and reservation protocol technical review. - Review of past similar cases. - Implications of the TIA standard published from same Roberts draft. TIA does not currently "borrow" a codepoint, but we needed to track this down. - Contextualization of this request to our very recent discussions (May 2) with ITU about protocol extensions and codepoints. These took a bit of time. Are you trying to construct a timeline from the minutes? I'm afraid the IESG minutes are made from a tool-form focussed on the documents and WG charters, and tend to have limited free-form information, something that really can only change if we add a person like the IAB has in Rich Draves.
