Hi Paul, Sowjanya and folks,
Thanks a lot for Paul and Sowjanya's reviews, we have modified our draft based on \
your comments.
The new version draft includes the following main changes:
1. Redesign the sections to make the structure more reasonable and the draft more \
readable.
2. Change the negotiation of support to the IKE_AUTH phase, and change the support \
notification's name.
3. Detail the optimization for rekeying IKE SAs, and use SA_UNCHANGED notification \
payload to replace SA payloads.
4. Detail the optimization for rekeying Child SAs, and use SA_TS_UNCHANGED \
notification payload to replace SA and TS payload.
5. For rekeying Child SAs, we currently remove the consideration that only omitting \
TS payloads, because we think this kind omitting will introduce more complexities. \
Initiator SA payload, Initiator TS payload, Responder SA payload and Responder TS \
payload, if either of these four payloads can be omitted, there will be up to 16 \
circumstances, that will be too complex.
Comments and reviews for the new version draft are very welcome.
Best Regards
Wei Pan

Abstract:
This document describes a method for reducing the size of the
Internet Key Exchange version 2 (IKEv2) exchanges at time of rekeying
IKE SAs and Child SAs by removing or making optional of SA & TS
payloads. Reducing size of IKEv2 exchanges is desirable for low
power consumption battery powered devices. It also helps to avoid IP
fragmentation of IKEv2 messages.
Please note that it may take a couple of minutes from the time of submission until \
the htmlized version and diff are available at tools.ietf.org.
