The following is an Essay Style Document Writeup:
The document shepherd is David Waltermire, and responsible area director is Kathleen Moriarty.
This document is intended to obsolete the RFC7321 (Proposed Standard) and define a current mandatory to implement algorithms requirements and usage for IPsec traffic. There is another document draft-ietf-ipsecme-rfc4307bis which does the same changes to the IKEv2, and both of the documents are mostly aligned to be same, except where there are different requirements for algorithms in IKEv2 vs ESP. It is requested that this draft and draft-ietf-ipsecme-rfc4307bis be grouped for completing the publication process.
2. Review and Consensus
The draft had no controversy. The draft has been discussed frequently on the mailing list and a lot of comments have been provided on list by people other than the authors. In addition to mailing list discussions, the draft has been presented and discussed during IETF meetings at Berlin (IETF96) and briefly at Seoul (IETF97). Most of the decisions on the algorithm levels were done already when discussing the companion document rfc4307bis.
3. Intellectual Property
The authors are not aware of any IPRs related to this document or the earlier versions of this document: RFC 7321, RFC 4835, or RFC 4305.
4. Other Points
IDnits complain about the IoT and UNSPECIFIED references, but they are not really references in real sense, but comments marked in . It also complains that there is an unused reference to RFC4309 which is only referenced in the figure, so id nits fails to see the reference. There are also two references to the obsolete documents RFC2393 and RFC4835. Both of these are intentional. The RFC2393 refers to the LZS compression and this is copy of the text from the IKEv2 IANA registry. The RFC4835 reference is for the previous version of this document and the text refers to the terminology started there.
