As anyone following the openflow-spec mailing list will have noticed, we are in the process of narrowing down the feature set for OpenFlow 0.9. The latest iteration of the feature list is now on the OpenFlow 0.9 wiki page. This is not final yet, and will change. Also none of this is in the publicly available reference implementation as of today.
Over the next weeks we will add these features to the reference implementation as well as controllers. We will also talk to some of our partners to understand the implications for their implementations. This will likely result in changes. If you have any feedback, please joint the discussion on openflow-spec.
