+OVN4NFV Project
+===============
+OVN complements the existing capabilities of OVS to add native support for
+virtual network abstractions such as virtual L2 & L3 overlays, L3 routing
+and security groups. Instead of treating ovsdb and Open Flow actions
+separately, OVN provides simpler interface for managing virtual networks.
+
+Besides the simpler interface, OVN takes care of transforming simple flow
+rules of virtual network to complex Open Flow rules on the Open vSwitches
+involved. The Openstack project networking-ovn implements the neutron api
+using OVN. As part of ovn4nfv project we would like to enable OVN along
+with the openstack neutron plugin networking-ovn as a deployable network
+control component in the OPNFV build. This would make it easier to manage
+virtual networks and push more of network intelligence to the edge onto the
+compute nodes. Since OVN has inherent support for containers, this would
+allow OPNFV to orchestrate container VNFs.
+
+Further this will make the controller architecture much more simpler and
+scalable by placing the controller (ovn-controller) next to the Open vSwitch.
