[IPsec] FW: I-D Action: draft-kampati-ipsecme-ikev2-sa-ts-payloads-opt-02.txt

Hi,

I've updated the IKEv2 rekeying optimization draft.
In the new version, IKE SAs rekeying optimization is optional now. It's up to the implementer to optimize the IKE SAs rekeying or not.
And the optimization processes are also simplified to two cases (before was three cases):
- The initiator sends the optimized rekeying request message, the responder accepts it and replies the optimized rekeying response message.
- The initiator sends the optimized rekeying request message, the responder refuses it and replies NO_PROPOASL_CHOSEN.

Review and comments are more than welcome.

Regards & Thanks!

> 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.
