What is Open vSwitch?
Open vSwitch is a production-quality, multilayer virtual switch licensed under the open-source Apache 2.0 license. It is designed to enable network automation through programmatic extension, while still supporting standard management interfaces and protocols such as NetFlow, sFlow, SPAN, RSPAN, CLI, LACP, and 802.1ag. Open vSwitch can operate both as a soft switch running within the hypervisor, and as the control stack for switching silicon.
