|  | 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. |
