The Open vSwitch team is pleased to announce the addition of wire compatibility for OpenFlow 1.0.  OpenFlow is a protocol that allows for the remote configuration of a switch's datapath.  You can read more about it here:


This support has not yet been merged into the master branch, since our internal controller-side applications aren't yet compatible.  The code is in the "openflow-1.0" branch and is based off of our master branch.  Until the big merge, we will keep it current with any changes made to master.

Currently, this release is fully wire-compatibile with OpenFlow 1.0.  The only feature that is missing for complete compatibility is slicing, which is a subset of QoS that allows traffic to be placed into specific queues on ports.  Support for that will be added within the next month or two.
