Control Plane OVS is the 6WIND implementation of Open vSwitch, based on http://www.openvswitch.org/.

Open vSwitch provides virtual switching, flow matching, and packet manipulation, configured via an OpenFlow controller or the command line.


Control Plane OVS provides the following capabilities:

  • Support for statistics synchronization with the fast path
  • Support for hitflags (a flow not hit by the kernel datapath, but hit by the fast path datapath, stays alive)
  • Support for direct addition/deletion of flows in the fast path shared memory



  • Open vSwitch kernel version from 2.6.32 to 4.3.
