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
