Hi, In general I agree with the document. I’ve just a couple of comments.
If we are talking about phases, we should not use migration, but transition. In many languages, when you translate migration, it means “dropping IPv4 and using only-IPv6”, which is not the case, and is not the spirit of the transition mechanism (IETF hasn’t defined migration mechanisms, right?). It seems a minor comment, but it confuses a lot non-english (and also English speakers, in my opinion). So please, replace all the occurrences of migration with transition. Regarding the different issues that are indicated because Happy Eyeballs, a possible solution is to increase the timers, so even if IPv6 is “slower” than IPv4, is not just a matter of 50 milliseconds (for example), but several seconds, so then IPv6 will get preference anyway. I’ve described this in a recent email related to the HE-update document (so you could use some of the text that I mention in that email): https://www.ietf.org/mail-archive/web/v6ops/current/msg26731.html Regards, Jordi -----Mensaje original----- De: sunset4 <sunset4-boun...@ietf.org> en nombre de <internet-dra...@ietf.org> Responder a: <internet-dra...@ietf.org> Fecha: lunes, 26 de junio de 2017, 19:07 Para: <i-d-annou...@ietf.org> CC: <sunset4@ietf.org> Asunto: [sunset4] I-D Action: draft-ietf-sunset4-gapanalysis-08.txt A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Sunsetting IPv4 of the IETF. Title : Gap Analysis for IPv4 Sunset Authors : Will(Shucheng) Liu Weiping Xu Cathy Zhou Tina Tsou Simon Perreault China Mobile Filename : draft-ietf-sunset4-gapanalysis-08.txt Pages : 11 Date : 2017-06-26 Abstract: Sunsetting IPv4 refers to the process of turning off IPv4 definitively. It can be seen as the final phase of the migration to IPv6. This memo enumerates difficulties arising when sunsetting IPv4, and identifies the gaps requiring additional work.
