21	  Open vSwitch is a multilayer Ethernet switch targeted at virtualized
22	  environments.  In addition to supporting a variety of features
23	  expected in a traditional hardware switch, it enables fine-grained
24	  programmatic extension and flow-based control of the network.  This
25	  control is useful in a wide variety of applications but is
26	  particularly important in multi-server virtualization deployments,
27	  which are often characterized by highly dynamic endpoints and the
28	  need to maintain logical abstractions for multiple tenants.
29
30	  The Open vSwitch datapath provides an in-kernel fast path for packet
31	  forwarding.  It is complemented by a userspace daemon, ovs-vswitchd,
32	  which is able to accept configuration from a variety of sources and
33	  translate it into packet processing rules.
34
35	  See http://openvswitch.org for more information and userspace
36	  utilities.
