OVN is virtual.networking for Open vSwitch and is developed within the OVS project. it is Linux foundation collaborative project.The first release of OVN comes with OVS 2.6

OVS is Open vSwitch. Open vSwitch is a production quality, multilayer virtual switch licensed under the open source Apache 2.0 license.
