+======================
+Installing vswitchperf
+======================
+
+The test suite requires Python 3.3 and relies on a number of other
+packages. These need to be installed for the test suite to function. To
+install Python 3.3 in CentOS 7, an additional repository, Software
+Collections (`a link`_) should be enabled.
+
+Installation of required packages and preparation of Python 3 virtual
+environment is performed by systems/build_base_machine.sh. It should be
+executed under user account, which will be used for vsperf execution.
+Please Note: Password-less sudo access must be configured for given
+user account before script is executed.
+
+Execution of installation script:
+
+.. code:: bash
+
+ cd systems
+ ./build_base_machine.sh
+
+Please note: you don't need to go into any of the systems subdirectories,
+simply run the top level build_base_machine.sh, your OS will be detected
+automatically.
+
+You will need to activate the virtual environment every time you start a
+new shell session. To activate, simple run:
+
+.. code:: bash
+
+ scl enable python33 bash
+ cd $HOME/vsperfenv
+ source bin/activate
+
+--------------
+
+Working Behind a Proxy
+======================
+
+If you're behind a proxy, you'll likely want to configure this before
+running any of the above. For example:
+
+ .. code:: bash
+
+ export http_proxy=proxy.mycompany.com:123
+ export https_proxy=proxy.mycompany.com:123
+
+.. _a link: http://www.softwarecollections.org/en/scls/rhscl/python33/

+=============================
+Getting Started with 'vsperf'
+=============================
+
+Hardware Requirements
+---------------------
+
+VSPERF requires one of the following traffic generators to run tests:
+
+- IXIA traffic generator (IxNetwork hardware) and a machine that runs the IXIA client software
+- Spirent traffic generator (TestCenter hardware chassis or TestCenter virtual in a VM) and a
+ VM to run the Spirent Virtual Deployment Service image, formerly known as "Spirent LabServer".
+
+Both test configurations, above, also require a CentOS Linux release 7.1.1503 (Core) host.
+
+vSwitch Requirements
+--------------------
+
+The vSwitch must support Open Flow 1.3 or greater.
+
+Installation
+------------
+
+Follow the `installation instructions <http://artifacts.opnfv.org/vswitchperf/docs/docs/guides/index.html>`__ to install.
+
+Traffic Generator Setup
+-----------------------
+Follow the `Traffic generator instructions <http://artifacts.opnfv.org/vswitchperf/docs/docs/guides/trafficgen.html>`__ to install and configure a suitable traffic generator.
+
+Cloning and building src dependencies
+-------------------------------------
+
+In order to run VSPERF, you will need to download DPDK and OVS. You can
+do this manually and build them in a preferred location, or you could
+use vswitchperf/src. The vswitchperf/src directory contains makefiles
+that will allow you to clone and build the libraries that VSPERF depends
+on, such as DPDK and OVS. To clone and build simply:
+
+ .. code-block:: console
+
+ cd src
+ make
+
+VSPERF can be used with OVS without DPDK support. In this case you have
+to specify path to the kernel sources by WITH\_LINUX parameter:
+
+ .. code-block:: console
+
+ cd src
+ make WITH_LINUX=/lib/modules/`uname -r`/build
+
+To build DPDK and OVS for PVP and PVVP testing with vhost_user as the guest
+access method, use:
+
+ .. code-block:: console
+
+ make VHOST_USER=y
+
+To build everything: Vanilla OVS, OVS with vhost_user as the guest access
+method and OVS with vhost_cuse access simply:
+
+ .. code-block:: console
+
+ make
+
+The vhost_user build will reside in src/ovs/
+The vhost_cuse build will reside in vswitchperf/src_cuse
+The Vanilla OVS build will reside in vswitchperf/src_vanilla
+
+To delete a src subdirectory and its contents to allow you to re-clone simply
+use:
+
+ .. code-block:: console
+
+ make clobber
+
+Configure the ``./conf/10_custom.conf`` file
+--------------------------------------------
+The ``10_custom.conf`` file is the configuration file that overrides
+default configurations in all the other configuration files in ``./conf``
+The supplied ``10_custom.conf`` file must be modified, as it contains
+configuration items for which there are no reasonable default values.
+
+The configuration items that can be added is not limited to the initial
+contents. Any configuration item mentioned in any .conf file in
+``./conf`` directory can be added and that item will be overridden by
+the custom configuration value.
+
+Using a custom settings file
+----------------------------
+
+If your ``10_custom.conf`` doesn't reside in the ``./conf`` directory
+of if you want to use an alternative configuration file, the file can
+be passed to ``vsperf`` via the ``--conf-file`` argument.
+
+ .. code-block:: console
+
+ ./vsperf --conf-file <path_to_settings_py> ...
+
+Note that configuration passed in via the environment (``--load-env``)
+or via another command line argument will override both the default and
+your custom configuration files. This "priority hierarchy" can be
+described like so (1 = max priority):
+
+1. Command line arguments
+2. Environment variables
+3. Configuration file(s)
+
+--------------
+
+Executing tests
+---------------
+
+Before running any tests make sure you have root permissions by adding
+the following line to /etc/sudoers:
+
+ .. code-block:: console
+
+ username ALL=(ALL) NOPASSWD: ALL
+
+username in the example above should be replaced with a real username.
+
+To list the available tests:
+
+ .. code-block:: console
+
+ ./vsperf --list
+
+To run a single test:
+
+ .. code-block:: console
+
+ ./vsperf $TESTNAME
+
+Where $TESTNAME is the name of the vsperf test you would like to run.
+
+To run a group of tests, for example all tests with a name containing
+'RFC2544':
+
+ .. code-block:: console
+
+ ./vsperf --conf-file=user_settings.py --tests="RFC2544"
+
+To run all tests:
+
+ .. code-block:: console
+
+ ./vsperf --conf-file=user_settings.py
+
+Some tests allow for configurable parameters, including test duration
+(in seconds) as well as packet sizes (in bytes).
+
+.. code:: bash
+
+ ./vsperf --conf-file user_settings.py
+ --tests RFC2544Tput
+ --test-param "duration=10;pkt_sizes=128"
+
+For all available options, check out the help dialog:
+
+ .. code-block:: console
+
+ ./vsperf --help
+
+Executing Vanilla OVS tests
+----------------------------
+If you have compiled all the variants of OVS in ''src/'' please skip
+step 1.
+
+1. Recompile src for Vanilla OVS testing
+
+ .. code-block:: console
+
+ cd src
+ make cleanse
+ make WITH_LINUX=/lib/modules/`uname -r`/build
+
+2. Update your ''10_custom.conf'' file to use the appropriate variables
+for Vanilla OVS:
+
+ .. code-block:: console
+
+ VSWITCH = 'OvsVanilla'
+ VSWITCH_VANILLA_PHY_PORT_NAMES = ['$PORT1', '$PORT1']
+
+Where $PORT1 and $PORT2 are the Linux interfaces you'd like to bind
+to the vswitch.
+
+3. Run test:
+
+ .. code-block:: console
+
+ ./vsperf --conf-file <path_to_settings_py>
+
+Please note if you don't want to configure Vanilla OVS through the
+configuration file, you can pass it as a CLI argument; BUT you must
+set the ports.
+
+ .. code-block:: console
+
+ ./vsperf --vswitch OvsVanilla
+
+
+Executing PVP and PVVP tests
+----------------------------
+To run tests using vhost-user as guest access method:
+
+1. Set VHOST_METHOD and VNF of your settings file to:
+
+ .. code-block:: console
+
+ VHOST_METHOD='user'
+ VNF = 'QemuDpdkVhost'
+
+2. Recompile src for VHOST USER testing
+
+ .. code-block:: console
+
+ cd src
+ make cleanse
+ make VHOST_USER=y
+
+3. Run test:
+
+ .. code-block:: console
+
+ ./vsperf --conf-file <path_to_settings_py>
+
+To run tests using vhost-cuse as guest access method:
+
+1. Set VHOST_METHOD and VNF of your settings file to:
+
+ .. code-block:: console
+
+ VHOST_METHOD='cuse'
+ VNF = 'QemuDpdkVhostCuse'
+
+2. Recompile src for VHOST USER testing
+
+ .. code-block:: console
+
+ cd src
+ make cleanse
+ make VHOST_USER=n
+
+3. Run test:
+
+ .. code-block:: console
+
+ ./vsperf --conf-file <path_to_settings_py>
+
+Executing PVP tests using Vanilla OVS
+-------------------------------------
+To run tests using Vanilla OVS:
+
+1. Set the following variables:
+
+ .. code-block:: console
+
+ VSWITCH = 'OvsVanilla'
+ VNF = 'QemuVirtioNet'
+
+ VANILLA_TGEN_PORT1_IP = n.n.n.n
+ VANILLA_TGEN_PORT1_MAC = nn:nn:nn:nn:nn:nn
+
+ VANILLA_TGEN_PORT2_IP = n.n.n.n
+ VANILLA_TGEN_PORT2_MAC = nn:nn:nn:nn:nn:nn
+
+ VANILLA_BRIDGE_IP = n.n.n.n
+
+ or use --test-param
+
+ ./vsperf --conf-file user_settings.py
+ --test-param "vanilla_tgen_tx_ip=n.n.n.n;
+ vanilla_tgen_tx_mac=nn:nn:nn:nn:nn:nn"
+
+
+2. Recompile src for Vanilla OVS testing
+
+ .. code-block:: console
+
+ cd src
+ make cleanse
+ make WITH_LINUX=/lib/modules/`uname -r`/build
+
+3. Run test:
+
+ .. code-block:: console
+
+ ./vsperf --conf-file <path_to_settings_py>
+
+Selection of loopback application for PVP and PVVP tests
+--------------------------------------------------------
+To select loopback application, which will perform traffic forwarding
+inside VM, following configuration parameter should be configured:
+
+ .. code-block:: console
+
+ GUEST_LOOPBACK = ['testpmd', 'testpmd']
+
+ or use --test-param
+
+ ./vsperf --conf-file user_settings.py
+ --test-param "guest_loopback=testpmd"
+
+Supported loopback applications are:
+
+ .. code-block:: console
+
+ 'testpmd' - testpmd from dpdk will be built and used
+ 'l2fwd' - l2fwd module provided by Huawei will be built and used
+ 'linux_bridge' - linux bridge will be configured
+ 'buildin' - nothing will be configured by vsperf; VM image must
+ ensure traffic forwarding between its interfaces
+
+Guest loopback application must be configured, otherwise traffic
+will not be forwarded by VM and testcases with PVP and PVVP deployments
+will fail. Guest loopback application is set to 'testpmd' by default.
+
+Code change verification by pylint
+----------------------------------
+Every developer participating in VSPERF project should run
+pylint before his python code is submitted for review. Project
+specific configuration for pylint is available at 'pylint.rc'.
+
+Example of manual pylint invocation:
+
+ .. code-block:: console
+
+ pylint --rcfile ./pylintrc ./vsperf
+
+GOTCHAs:
+--------
+
+OVS with DPDK and QEMU
+~~~~~~~~~~~~~~~~~~~~~~~
+If you encounter the following error: "before (last 100 chars):
+'-path=/dev/hugepages,share=on: unable to map backing store for
+hugepages: Cannot allocate memory\r\n\r\n" with the PVP or PVVP
+deployment scenario, check the amount of hugepages on your system:
+
+.. code:: bash
+
+ cat /proc/meminfo | grep HugePages
+
+
+By default the vswitchd is launched with 1Gb of memory, to change
+this, modify --socket-mem parameter in conf/02_vswitch.conf to allocate
+an appropriate amount of memory:
+
+.. code:: bash
+
+ VSWITCHD_DPDK_ARGS = ['-c', '0x4', '-n', '4', '--socket-mem 1024,0']
+

+===========================
+'vsperf' Traffic Gen Guide
+===========================
+
+Overview
+---------------------
+VSPERF supports the following traffic generators:
+
+ * Dummy (DEFAULT): Allows you to use your own external
+ traffic generator.
+ * IXIA (IxNet and IxOS)
+ * Spirent TestCenter
+
+To see the list of traffic gens from the cli:
+
+ .. code-block:: console
+
+ ./vsperf --list-trafficgens
+
+This guide provides the details of how to install
+and configure the various traffic generators.
+
+Background Information
+----------------------
+The traffic default configuration can be found in
+tools/pkt_gen/trafficgen/trafficgenhelper.py, and is configured as
+follows:
+
+ .. code-block:: console
+
+ TRAFFIC_DEFAULTS = {
+ 'l2': {
+ 'framesize': 64,
+ 'srcmac': '00:00:00:00:00:00',
+ 'dstmac': '00:00:00:00:00:00',
+ 'srcport': 3000,
+ 'dstport': 3001,
+ },
+ 'l3': {
+ 'proto': 'tcp',
+ 'srcip': '1.1.1.1',
+ 'dstip': '90.90.90.90',
+ },
+ 'vlan': {
+ 'enabled': False,
+ 'id': 0,
+ 'priority': 0,
+ 'cfi': 0,
+ },
+ }
+
+The framesize paramter can be overridden from the configuration
+files by adding the following to your custom configuration file
+``10_custom.conf``:
+
+ .. code-block:: console
+
+ TRAFFICGEN_PKT_SIZES = (64, 128,)
+
+OR from the commandline:
+
+ .. code-block:: console
+
+ ./vsperf --test-param "pkt_sizes=x,y" $TESTNAME
+
+You can also modify the traffic transmission duration and the number
+of trials run by the traffic generator by extending the example
+commandline above to:
+
+ .. code-block:: console
+
+ ./vsperf --test-param "pkt_sizes=x,y;duration=10;rfc2455_trials=3" $TESTNAME
+
+Dummy Setup
+------------
+To select the Dummy generator please add the following to your
+custom configuration file ``10_custom.conf``.
+
+
+ .. code-block:: console
+
+ TRAFFICGEN = 'Dummy'
+
+OR run ``vsperf`` with the ``--trafficgen`` argument
+
+ .. code-block:: console
+
+ ./vsperf --trafficgen Dummy $TESTNAME
+
+Where $TESTNAME is the name of the vsperf test you would like to run.
+This will setup the vSwitch and the VNF (if one is part of your test)
+print the traffic configuration and prompt you to transmit traffic
+when the setup is complete.
+
+ .. code-block:: console
+
+ Please send 'continuous' traffic with the following stream config:
+ 30mS, 90mpps, multistream False
+ and the following flow config:
+ {
+ "flow_type": "port",
+ "l3": {
+ "srcip": "1.1.1.1",
+ "proto": "tcp",
+ "dstip": "90.90.90.90"
+ },
+ "traffic_type": "continuous",
+ "multistream": 0,
+ "bidir": "True",
+ "vlan": {
+ "cfi": 0,
+ "priority": 0,
+ "id": 0,
+ "enabled": false
+ },
+ "frame_rate": 90,
+ "l2": {
+ "dstport": 3001,
+ "srcport": 3000,
+ "dstmac": "00:00:00:00:00:00",
+ "srcmac": "00:00:00:00:00:00",
+ "framesize": 64
+ }
+ }
+ What was the result for 'frames tx'?
+
+When your traffic gen has completed traffic transmission and provided
+the results please input these at the vsperf prompt. vsperf will try
+to verify the input:
+
+ .. code-block:: console
+
+ Is '$input_value' correct?
+
+Please answer with y OR n.
+
+VPSERF will ask you for:
+ * Result for 'frames tx'
+ * Result for 'frames rx'
+ * Result for 'min latency'
+ * Result for 'max latency'
+ * Result for 'avg latency'
+
+Finally vsperf will print out the results for your test and generate the
+appropriate logs and csv files.
+
+
+IXIA Setup
+----------
+
+On the CentOS 7 system
+~~~~~~~~~~~~~~~~~~~~~~
+
+You need to install IxNetworkTclClient$(VER\_NUM)Linux.bin.tgz.
+
+On the IXIA client software system
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Find the IxNetwork TCL server app (start -> All Programs -> IXIA ->
+IxNetwork -> IxNetwork\_$(VER\_NUM) -> IxNetwork TCL Server)
+
+Right click on IxNetwork TCL Server, select properties - Under shortcut tab in
+the Target dialogue box make sure there is the argument "-tclport xxxx"
+where xxxx is your port number (take note of this port number you will
+need it for the 10\_custom.conf file).
+
+.. image:: TCLServerProperties.png
+
+Hit Ok and start the TCL server application
+
+Spirent Setup
+-------------
+
+Spirent installation files and instructions are available on the
+Spirent support website at:
+
+http://support.spirent.com
+
+Select a version of Spirent TestCenter software to utilize. This example
+will use Spirent TestCenter v4.57 as an example. Substitute the appropriate
+version in place of 'v4.57' in the examples, below.
+
+On the CentOS 7 System
+~~~~~~~~~~~~~~~~~~~~~~
+
+Download and install the following:
+
+Spirent TestCenter Application, v4.57 for 64-bit Linux Client
+
+Spirent Virtual Deployment Service (VDS)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Spirent VDS is required for both TestCenter hardware and virtual
+chassis in the vsperf environment. For installation, select the version
+that matches the Spirent TestCenter Application version. For v4.57,
+the matching VDS version is 1.0.55. Download either the ova (VMware)
+or qcow2 (QEMU) image and create a VM with it. Initialize the VM
+according to Spirent installation instructions.
+
+Using Spirent TestCenter Virtual (STCv)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+STCv is available in both ova (VMware) and qcow2 (QEMU) formats. For
+VMware, download:
+
+Spirent TestCenter Virtual Machine for VMware, v4.57 for Hypervisor - VMware ESX.ESXi
+
+Virtual test port performance is affected by the hypervisor configuration. For
+best practice results in deploying STCv, the following is suggested:
+
+- Create a single VM with two test ports rather than two VMs with one port each
+- Set STCv in DPDK mode
+- Give STCv 2*n + 1 cores, where n = the number of ports. For vsperf, cores = 5.
+- Turning off hyperthreading and pinning these cores will improve performance
+- Give STCv 2 GB of RAM
+
+To get the highest performance and accuracy, Spirent TestCenter hardware is
+recommended. vsperf can run with either stype test ports.
