Control Plane OVS is the 6WIND implementation of Open vSwitch, based on Open vSwitch v2.9.3.

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.
