Q: When will there be updates to OpenFlow? What updates will be coming?

A: ONF announced the OpenFlow v1.3 test specification in late 2015. The organization is actively working on TTP (table type patterns), a standard for precisely describing the forwarding behavior of an OpenFlow compliant dataplane. This is needed because OpenFlow became so flexible and the realm of possible OpenFlow implementations became quite broad. It’s now important that we make it possible to specify what exactly each implementation is capable of.

Beyond TTP, we will be driving the disaggregation of OpenFlow, separating the wireline protocol (communication between the controller and the data plane) from the programming of the data plane in order to allow each to evolve independently.
