-What is Open vSwitch?
----------------------
-
-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
-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:
-
- * Standard 802.1Q VLAN model with trunk and access ports
- * NIC bonding with or without LACP on upstream switch
- * NetFlow, sFlow(R), and mirroring for increased visibility
- * QoS (Quality of Service) configuration, plus policing
- * Geneve, GRE, GRE over IPSEC, VXLAN, and LISP tunneling
- * 802.1ag connectivity fault management
- * OpenFlow 1.0 plus numerous extensions
- * Transactional configuration database with C and Python bindings
- * High-performance forwarding using a Linux kernel module
-
-The included Linux kernel module supports Linux 2.6.32 and up, with
-testing focused on 2.6.32 with Centos and Xen patches. Open vSwitch
-also has special support for Citrix XenServer and Red Hat Enterprise
-Linux hosts.
-
-Open vSwitch can also operate, at a cost in performance, entirely in
-userspace, without assistance from a kernel module. This userspace
-implementation should be easier to port than the kernel-based switch.
-It is considered experimental.
-
-What's here?
-------------
-
-The main components of this distribution are:
-
- * 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-dpctl, a tool for configuring the switch kernel module.
-
- * Scripts and specs for building RPMs for Citrix XenServer and Red
- Hat Enterprise Linux. The XenServer RPMs allow Open vSwitch to
- be installed on a Citrix XenServer host as a drop-in replacement
- for its switch, with additional functionality.
-
- * ovs-vsctl, a utility for querying and updating the configuration
- of ovs-vswitchd.
-
- * ovs-appctl, a utility that sends commands to running Open
- vSwitch daemons.
-
-Open vSwitch also provides some tools:
-
- * ovs-ofctl, a utility for querying and controlling OpenFlow
- switches and controllers.
-
- * ovs-pki, a utility for creating and managing the public-key
- infrastructure for OpenFlow switches.
-
- * ovs-testcontroller, a simple OpenFlow controller that may be useful
- for testing (though not for production).
-
- * A patch to tcpdump that enables it to parse OpenFlow messages.

-What other documentation is available?
---------------------------------------
-
-To install Open vSwitch on a regular Linux or FreeBSD host, please
-read INSTALL. For specifics around installation on a specific
-platform, please see one of these files:
-
- - INSTALL.Debian
- - INSTALL.Fedora
- - INSTALL.RHEL
- - INSTALL.XenServer
-
-To use Open vSwitch...
-
- - ...with KVM on Linux, read INSTALL, read INSTALL.KVM.
-
- - ...with Libvirt, read INSTALL.Libvirt.
-
- - ...without using a kernel module, read INSTALL.userspace.
-
-For answers to common questions, read FAQ.
-
-To learn how to set up SSL support for Open vSwitch, read INSTALL.SSL.
-
-To learn about some advanced features of the Open vSwitch software
-switch, read the tutorial in tutorial/Tutorial.
-
-Each Open vSwitch userspace program is accompanied by a manpage. Many
-of the manpages are customized to your configuration as part of the
-build process, so we recommend building Open vSwitch before reading
-the manpages.
