<div dir="ltr">Hi,<div><br></div><div>Since I was quoted, I would like to take the blame on behalf on the Neutron core reviewer/drivers team for not providing the right guidance to resolve the apparent conflict between the two proposals.</div><div><br></div><div>As some reviewers mentioned, we should really strive to catch two birds with one stone, and ensure that, if at all possible, the same API can address both use cases presented. In this case, it sounds to me that the API proposed by the networking-sfc sub-project is more comprehensive, it has taken the steps to evolve independently from the Neutron core platform, and it has been iterated on multiple times. Surely we can spin off (the forwarding engine) from the spin off (the SFC API), but that would feel like an overkill, especially when both have very little code to show for (and everyone knows that code wins in OpenStack).</div><div><br></div><div>We should have provided Yuji Azama feedback a lot earlier in the process but we didn't.

</span>I think there is overlap between the two APIs. Let's keep collaborating<br>
on both the networking-sfc and packet forwarding APIs, to see where we<br>
have commonality. I think Cathy's initial e-mail may have ruffled<br>
feathers - and I'd like to smooth them out again. I think the statement<br>
"we only need one API" is far too premature.<br>
<br>
Let's play nice with the other API proposals, yes?<br>
