I agree with Dave Wierbowsk, deletion will still occur (for the old IKE SA)
so deleting it while Host B is retransmitting (or waiting for some timer to
retrasmit) seems to make most sense. Host B notices the delete payload (or
NO_ADDITIONAL_SAS), stops retransmitting the request and go on as if the

Here are my comments:
- Is Section 1.2 necessary? None of these terms are used in this fashion
in this document.
- page 8, "sees an new" => "sees a new"
- page 8, "in the Section 8" => "in Section 8"
- page 12, excessive space in "i.e. UDP encapsulated"; perhaps replace
with comma.
- page 16,

Suggest either "being part *of* a" or "being a willing participant in a".

As I said in my earlier note, I have removed all discussion of RFC 3948 from
this new text. RFC 3948 i
Thanks for the two editorial notes; fixed.
We want more input on the following:

Hi Tero,
Given that the existing ESP header is integrity-protected, I don't see the
downside to adding the same protection for the new header. On the other hand,
this would eliminate a whole class of vulnerabilities. We still have a few
reserved bits in the WESP header, and you don't want to fi

There is the same typo my original text had:

Hi all
The draft linked below is a problem statement draft about using
IKE&IPsec implementations in high availability and load sharing
configurations.
I will describe this at tomorrows Interim meeting.
Comments are welcome, of course, both on the list and at tomorrow's
session.
