| 22 | Open vSwitch is a multilayer Ethernet switch targeted at virtualized |
| 23 | environments. In addition to supporting a variety of features |
| 24 | expected in a traditional hardware switch, it enables fine-grained |
| 25 | programmatic extension and flow-based control of the network. This |
| 26 | control is useful in a wide variety of applications but is |
| 27 | particularly important in multi-server virtualization deployments, |
| 28 | which are often characterized by highly dynamic endpoints and the |
| 29 | need to maintain logical abstractions for multiple tenants. |

| 31 | The Open vSwitch datapath provides an in-kernel fast path for packet |
| 32 | forwarding. It is complemented by a userspace daemon, ovs-vswitchd, |
| 33 | which is able to accept configuration from a variety of sources and |
| 34 | translate it into packet processing rules. |
