As a co-author, I support adoption of tcpcrypt.

Hi all,

please indicate if you support adoption of draft-bittau-tcpinc-tcpcrypt-04 as a tcpinc working group item, or not, by

draft-bittau-tcpinc-tcpcrypt is one candidate for tcpinc where the first version of that draft was proposed about a year ago. In the mean time this proposal has received broad feedback. The latest version was published only a few days ago, however, this version adapts the tcpcrypt proposal to tcp-eno, which we adopted as a wg item a couple weeks ago, and therefore simplifies the draft.

If you do not support adoption of this document because you think it is not in scope for the wg or has fundamental technicals flaws and would therefore harm the goals of the wg, it would be great if you could given some reasoning/explanation with your response.

This is solely an adoption call for draft-bittau-tcpinc-tcpcrypt independent of any other documents. If you have a personal preference for a different approach that should not be a reason to reject this adoption. Forcing the wg to make a decision has not worked previously, and even though both proposed approaches have evolved, I do not see any indication that the wg is now ready to make a decision. The goal of this adoption call is to figure out if there is enough interest and energy to further follow the approach as outlined in draft-bittau-tcpinc-tcpcrypt-04. A separate adoption call for the other proposed solution will following.

This process may lead to a situation where the wg will adopt and work on two solution approaches. This does not mean that the wg will publish two (incompatible) approaches, as this would not fulfill our charter. If we end up adopting more than one approach, I currently see three way to proceed:

1) Both approaches (naturally) converge into one approach.

2) We work on both approaches to get them into a (similar) state where the wg is able to make a decision (and withdraw the other doc).

3) We publish both approaches as different 'versions' of tcpinc that can be negotiated in the tcp-eno handshake, where at least one of them is mandatory to support/implement.

Thanks!
