SOI QUESTION: 4.1 Control channel vs. separate protocols




Notes from the chair:

This question basically introduces the various questions raised by
section 4 of the soi-features document, which goes to one of the biggest
differences to the JFK and IKEv2 approach.


4. One or two phases

4.1 Control channel vs. separate protocols

4.1.A) [Meta question, that will be answered by the other questions in
section 4.]  Does SOI need a control channel for SA management?  Or is
it acceptable to piggy back SA management as a part of other parts of
the SOI protocol?

Implications from the Scenarios:

VPN: <<<This calls out a need for either a two-phased approach for
SOI, or a single-phased approach that is sufficiently fast, where
"fast" represents an optimal combination of "number of messages" and
"computational expenditure".>>> [[[4.1]]]
