For Commercial OEMs AND ODMs For OEMs and ODMs who distribute Indigo with their products, and do not license and distribute their source code under the EPLv1, Big Switch Networks provides a flexible commercial license. In addition, if you are a company with an existing relationship with Broadcom, who wishes to license our Broadcom forwarding driver, please contact us. – See more at: http://www.projectfloodlight.org/indigo/#sthash.dGwzuVcf.dpuf

Indigo is an open source project aimed at enabling support for OpenFlow on physical and hypervisor switches.Big Switch has helped numerous companies OpenFlow enable their equipment, and we provide firmware for a number of popular switches.

Open vSwitch can operate both as a soft switch running within the hypervisor, and as the control stack for switching silicon. It has been ported to multiple virtualization platforms and switching chipsets. It is the default switch in XenServer 6.0, the Xen Cloud Platform and also supports Xen, KVM, Proxmox VE and VirtualBox. It has also been integrated into many virtual management systems including OpenStack, openQRM, OpenNebula and oVirt. The kernel datapath is distributed with Linux, and packages are available for Ubuntu, Debian, and Fedora. Open vSwitch is also supported on FreeBSD and NetBSD. The Open vSwitch release in development has been ported to DPDK.

Q: Does Open vSwitch only work on Linux?

A: No, Open vSwitch has been ported to a number of different operating systems and hardware platforms. Most of the development work occurs on Linux, but the code should be portable to any POSIX system. We’ve seen Open vSwitch ported to a number of different platforms, including FreeBSD, Windows, and even non-POSIX embedded systems.

By definition, the Open vSwitch Linux kernel module only works on Linux and will provide the highest performance. However, a userspace datapath is available that should be very portable.
