What is Open vSwitch? From openvswitch.org: “Open vSwitch is a production quality, multilayer virtual switch licensed under the open source Apache 2.0 license. It is designed to enable massive network automation through programmatic extension, while still supporting standard management interfaces and protocols (e.g. NetFlow, sFlow, SPAN, RSPAN, CLI, LACP, 802.1ag).”
Where is Open vSwitch Used? ● Broad support: – Linux, FreeBSD, NetBSD, Windows, ESX – KVM, Xen, Docker, VirtualBox, Hyper-V, … – OpenStack, CloudStack, OpenNebula, … ● Widely used: – Most popular OpenStack networking backend – Default network stack in XenServer – 1,440 hits in Google Scholar – Thousands of subscribers to OVS mailing lists
