Hi Cathy,

A project called "neutron-classifier [1]" is also there addressing the same
use case. Let's sync up and avoid work duplicity.

Hi everyone,

Per Armando’s request, Louis and I are looking into the following features
for Newton cycle.

·         Neutron Common FC used for SFC, QoS, Tap as a service etc.,

·         OVS Agent extension

Some of you might know that we already developed a FC in networking-sfc
project and QoS also has a FC. It makes sense that we have one common FC in
Neutron that could be shared by SFC, QoS, Tap as a service etc. features in

Different features may extend OVS agent and add different new OVS flow
tables to support their new functionality. A mechanism is needed to ensure
consistent OVS flow table modification when multiple features co-exist.
AFAIK, there is some preliminary work on this, but it is not a complete
solution yet.

We will like to start these effort by collecting requirements and then
posting specifications for review. If any of you would like to join this
effort, please chime in. We can set up a meet-up session in the Summit to
discuss this face-in-face.
