The INTERMEDIATE draft explicitly allows to specify more than one roundtrip, and leaves the order of those exchanges to the documents introducing the new roundtrips
It allows it, but that does not mean we want things to go in serial when they could go in parallel :)
If I wrote a draft today that adds a single large Notify in an INTERMEDIATE exchange, it would not be obvious how it would interact with e.G. the hybrid KE that adds up to 7 additional INTERMEDIATE roundtrips.
The draft should be clear on how to handle that. It should not depend on having its payload in the very first INTERMEDIATE (since then all new things would always all need to be there and at some point we are full again)
I would have to explicitly specify in my draft that this additional Notify is always added to the first INTERMEDIATE specified in the Hybrid KE, if I wanted it to be there.
I don't think we would allow you to do that. Because if another draft insisted on the same thing, who gets to win?
Otherwise it could be added to any of the INTERMEDIATES in that draft, or to a new INTERMEDIATE before all hybrid KE ones, or to a new INTERMEDIATE after the hybrid KEs...
Yes. ping pong for everyone :) Paul _______________________________________________ IPsec mailing list [email protected] https://www.ietf.org/mailman/listinfo/ipsec
