what’s essentially a new API, but let’s see. I invite you to read the spec [1] thoroughly. Let’s continue there so we can better scope the discussion.<o:p></o:p></span></p>

<p class="MsoNormal">Just a quick glance over the proposal seems like the networking-sfc also does the same. In addition, networking-sfc is successfully integrated with ONOS[1] and planned for ODL[2], OVN [3] & Tacker[4] (without any issues with the existing
API's so far). In addition, If we feel the existing networking-sfc API's has issues then let's enhance them rather than a fresh effort from the scratch.<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">We've been investigating options in/around OpenStack for supporting Service Function Chaining. The networking-sfc project has made significant progress in this space, and we see
lots of value in what has been completed. However, when we looked at the related IETF specs on SFC we concluded that there would be value in further developing an SFC API and related classification functionality to enhance the alignment between the work in
the OpenStack community with the standards work. We would like to propose the SFC part as a potential networking-sfc v2 API, but are open to other options too based on your feedback.

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">The networking-sfc initiative so far has been pretty autonomous. The project has its own launchpad project [1] and its own docs to document APIs and proposals [2]. During the long
journey that Neutron has been through, we have been adjusting how to manage the project in order to strike a good balance between development agility, product stability and community needs. We're always looking forward to improving that balance and this means
that how we track certain initiatives may evolve in the future. For now, it's probably best to target the mailing list with tag [networking-sfc] (in addition to neutron), as well as the project noted below.<o:p></o:p></p>
