Our goal is to implement a production +quality switch platform that supports standard management interfaces +(e.g. NetFlow, RSPAN, ERSPAN, IOS-like CLI), and opens the forwarding +functions to programmatic extension and control. + +Open vSwitch is well suited to function as a virtual switch in VM +environments. In addition to exposing standard control and visibility +interfaces to the virtual networking layer, it was designed to support +distribution across multiple physical servers. Open vSwitch supports +multiple Linux-based virtualization technologies including +Xen/XenServer, KVM, and VirtualBox. + +The bulk of the code is written in platform-independent C and is +easily ported to other environments. The current release of Open +vSwitch supports the following features: + + * Visibility into inter-VM communication via NetFlow, SPAN, and RSPAN + * Standard 802.1Q VLAN model with trunking + * Per VM policing + * NIC bonding with source-MAC load balancing + * Kernel-based forwarding + * Support for OpenFlow + * Compatibility layer for the Linux bridging code Open vSwitch supports Linux 2.6.15 and up, with testing focused on 2.6.18 with Centos and Xen patches and version 2.6.26 from kernel.org.
