Open vSwitch is an open-source software switch designed to be used as a virtual switch.

Open vSwitch is a production quality open source software switch designed to be used as a vswitch in virtualized server environments.

Open vSwitch supports standard management interfaces (e.g. sFlow, NetFlow, IPFIX, RSPAN, CLI), and is open to programmatic extension and control using OpenFlow and the OVSDB management protocol.
