Open vSwitch is a multilayer software switch licensed under the open
source Apache 2 license. 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.
+(e.g. NetFlow, sFlow(R), 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
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
+ * Visibility into inter-VM communication via NetFlow, sFlow, SPAN,
+ and RSPAN
* Standard 802.1Q VLAN model with trunking
* Per VM policing
* NIC bonding with source-MAC load balancing
* ovs-vswitchd, a daemon that implements the switch, along with
a companion Linux kernel module for flow-based switching.
+ * ovsdb-server, a lightweight database server that ovs-vswitchd
+ queries to obtain its configuration.
+
* ovs-brcompatd, a daemon that allows ovs-vswitchd to act as a
drop-in replacement for the Linux bridge in many environments,
along with a companion Linux kernel module to intercept bridge
* ovs-appctl, a utility that sends commands to running Open
vSwitch daemons.
+ * ovsdbmonitor, a GUI tool for remotely viewing OVS databases and
+ OpenFlow flow tables.

Open vSwitch also provides an OpenFlow implementation and tools for
those interested in OpenFlow but not additional Open vSwitch features:
