+ Open vSwitch is a multilayer Ethernet switch targeted at virtualized
+ environments. In addition to supporting a variety of features
+ expected in a traditional hardware switch, it enables fine-grained
+ programmatic extension and flow-based control of the network. This
+ control is useful in a wide variety of applications but is
+ particularly important in multi-server virtualization deployments,
+ which are often characterized by highly dynamic endpoints and the
+ need to maintain logical abstractions for multiple tenants.
+
+ The Open vSwitch datapath provides an in-kernel fast path for packet
+ forwarding. It is complemented by a userspace daemon, ovs-vswitchd,
+ which is able to accept configuration from a variety of sources and
+ translate it into packet processing rules.
+
+ See http://openvswitch.org for more information and userspace
+ utilities.
