When responding, please keep the subject line intact and reply to all email addresses included in the To and CC lines. (Feel free to cut this introductory paragraph, however.) Please refer to http://www.ietf.org/iesg/statement/discuss-criteria.html for more information about IESG DISCUSS and COMMENT positions. ---------------------------------------------------------------------- DISCUSS: ---------------------------------------------------------------------- Please see my discuss on draft-ietf-6man-udpzero, and note that I hope to get to yes on this draft also, since I support the liberalization of this protocol design when used for tunnelling. Specifically point 6 in this draft is relevant to this discussion. Additionally a tunnel may not have any way of knowing if the payload is protected (as you suggest), since normally a tunnel has no knowledge of the payload characteristics. In point 7 you suggest that an application cannot rely on packet length. When PWs are used for tunneling we rely on exactly that (except in the case of packets shorter than 64 octets for Ethenet padding reasons), and I am not aware of any reported issues. Thus when the application is tunnel encap/decap there is a body of evidence that suggests that this OK. ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- There is some text in the earlier part of document that looks like it should be written in RFC2119 format. In this case it is not important because the normative change is later and this used RFC2119 directives, however the authors should consider making the document self consistent in this regard. -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected] Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
