+
+Integration tests
+=================
+
+VSPERF includes a set of integration tests defined in conf/integration.
+These tests can be run by specifying --integration as a parameter to vsperf.
+Current tests in conf/integration include switch functionality and Overlay
+tests.
+
+Tests in the conf/integration can be used to test scaling of different switch
+configurations by adding steps into the test case.
+
+For the overlay tests VSPERF supports VXLAN, GRE and GENEVE tunneling protocols.
+Testing of these protocols is limited to unidirectional traffic and
+P2P (Physical to Physical scenarios).
+
+NOTE: The configuration for overlay tests provided in this guide is for
+unidirectional traffic only.
+
+Executing Integration Tests
+---------------------------
+
+To execute integration tests VSPERF is run with the integration parameter. To
+view the current test list simply execute the following command:
+
+.. code-block:: console
+
+ ./vsperf --integration --list
+
+The standard tests included are defined inside the
+``conf/integration/01_testcases.conf`` file.
+
+Executing Tunnel encapsulation tests
+------------------------------------
+
+The VXLAN OVS DPDK encapsulation tests requires IPs, MAC addresses,
+bridge names and WHITELIST_NICS for DPDK.
+
+NOTE: Only Ixia traffic generators currently support the execution of the tunnel
+encapsulation tests. Support for other traffic generators may come in a future
+release.
+
+Default values are already provided. To customize for your environment, override
+the following variables in you user_settings.py file:
+
+ .. code-block:: python
+
+ # Variables defined in conf/integration/02_vswitch.conf
+ # Tunnel endpoint for Overlay P2P deployment scenario
+ # used for br0
+ VTEP_IP1 = '192.168.0.1/24'
+
+ # Used as remote_ip in adding OVS tunnel port and
+ # to set ARP entry in OVS (e.g. tnl/arp/set br-ext 192.168.240.10 02:00:00:00:00:02

+
+Step driven tests
+=================
+
+In general, test scenarios are defined by a ``deployment`` used in the particular
+test case definition. The chosen deployment scenario will take care of the vSwitch
+configuration, deployment of VNFs and it can also affect configuration of a traffic
+generator. In order to allow a more flexible way of testcase scripting, VSPERF supports
+a detailed step driven testcase definition. It can be used to configure and
+program vSwitch, deploy and terminate VNFs, execute a traffic generator,
+modify a VSPERF configuration, execute external commands, etc.
+
+Execution of step driven tests is done on a step by step work flow starting
+with step 0 as defined inside the test case. Each step of the test increments
+the step number by one which is indicated in the log.
+
+.. code-block:: console
+
+ (testcases.integration) - Step 0 'vswitch add_vport ['br0']' start
+
+Step driven tests can be used for both performance and integration testing.
+In case of integration test, each step in the test case is validated. If a step
+does not pass validation the test will fail and terminate. The test will continue
+until a failure is detected or all steps pass. A csv report file is generated after
+a test completes with an OK or FAIL result.
+
+In case of performance test, the validation of steps is not performed and
+standard output files with results from traffic generator and underlying OS
+details are generated by vsperf.
+
+Step driven testcases can be used in two different ways:
+
+ # description of full testcase - in this case ``clean`` deployment is used
+ to indicate that vsperf should neither configure vSwitch nor deploy any VNF.
+ Test shall perform all required vSwitch configuration and programming and
+ deploy required number of VNFs.
+
+ # modification of existing deployment - in this case, any of supported
+ deployments can be used to perform initial vSwitch configuration and
+ deployment of VNFs. Additional actions defined by TestSteps can be used
+ to alter vSwitch configuration or deploy additional VNFs. After the last
+ step is processed, the test execution will continue with traffic execution.
+
+Test objects and their functions
+--------------------------------
+
+Every test step can call a function of one of the supported test objects. The list
+of supported objects and their most common functions follows:
+
+ * ``vswitch`` - provides functions for vSwitch configuration
+
+ List of supported functions:
+
+ * ``add_switch br_name`` - creates a new switch (bridge) with given ``br_name``
+ * ``del_switch br_name`` - deletes switch (bridge) with given ``br_name``
+ * ``add_phy_port br_name`` - adds a physical port into bridge specified by ``br_name``
+ * ``add_vport br_name`` - adds a virtual port into bridge specified by ``br_name``
+ * ``del_port br_name port_name`` - removes physical or virtual port specified by
+ ``port_name`` from bridge ``br_name``
+ * ``add_flow br_name flow`` - adds flow specified by ``flow`` dictionary into
+ the bridge ``br_name``; Content of flow dictionary will be passed to the vSwitch.
+ In case of Open vSwitch it will be passed to the ``ovs-ofctl add-flow`` command.
+ Please see Open vSwitch documentation for the list of supported flow parameters.
+ * ``del_flow br_name [flow]`` - deletes flow specified by ``flow`` dictionary from
+ bridge ``br_name``; In case that optional parameter ``flow`` is not specified
+ or set to an empty dictionary ``{}``, then all flows from bridge ``br_name``
+ will be deleted.
+ * ``dump_flows br_name`` - dumps all flows from bridge specified by ``br_name``
+ * ``enable_stp br_name`` - enables Spanning Tree Protocol for bridge ``br_name``
+ * ``disable_stp br_name`` - disables Spanning Tree Protocol for bridge ``br_name``
+ * ``enable_rstp br_name`` - enables Rapid Spanning Tree Protocol for bridge ``br_name``
+ * ``disable_rstp br_name`` - disables Rapid Spanning Tree Protocol for bridge ``br_name``
+
+ Examples:
+
+ .. code-block:: python
+
+ ['vswitch', 'add_switch', 'int_br0']
+
+ ['vswitch', 'del_switch', 'int_br0']
+
+ ['vswitch', 'add_phy_port', 'int_br0']

+ 'idle_timeout': '0'}],
+
+ ['vswitch', 'enable_rstp', 'int_br0']
+
+ * ``vnf[ID]`` - provides functions for deployment and termination of VNFs; Optional
+ alfanumerical ``ID`` is used for VNF identification in case that testcase
+ deploys multiple VNFs.
+
+ List of supported functions:
+
+ * ``start`` - starts a VNF based on VSPERF configuration
+ * ``stop`` - gracefully terminates given VNF
+
+ Examples:
+
+ .. code-block:: python
+
+ ['vnf1', 'start']
+ ['vnf2', 'start']
+ ['vnf2', 'stop']
+ ['vnf1', 'stop']
+
+ * ``trafficgen`` - triggers traffic generation
+
+ List of supported functions:
+
+ * ``send_traffic traffic`` - starts a traffic based on the vsperf configuration
+ and given ``traffic`` dictionary. More details about ``traffic`` dictionary
+ and its possible values are available at :ref:`Traffic Generator Integration Guide
+ <step-5-supported-traffic-types>`
+

+
+Test Macros
+-----------
+
+Test profiles can include macros as part of the test step. Each step in the
+profile may return a value such as a port name. Recall macros use #STEP to
+indicate the recalled value inside the return structure. If the method the
+test step calls returns a value it can be later recalled, for example:
+
+.. code-block:: python
+
+ {
+ "Name": "vswitch_add_del_vport",
+ "Deployment": "clean",
+ "Description": "vSwitch - add and delete virtual port",
+ "TestSteps": [
+ ['vswitch', 'add_switch', 'int_br0'], # STEP 0
+ ['vswitch', 'add_vport', 'int_br0'], # STEP 1
+ ['vswitch', 'del_port', 'int_br0', '#STEP[1][0]'], # STEP 2
+ ['vswitch', 'del_switch', 'int_br0'], # STEP 3
+ ]
+ }
+
+This test profile uses the vswitch add_vport method which returns a string
+value of the port added. This is later called by the del_port method using the
+name from step 1.
+
+It is also possible to use negative indexes in step macros. In that case
+``#STEP[-1]`` will refer to the result from previous step, ``#STEP[-2]``
+will refer to result of step called before previous step, etc. It means,
+that you could change ``STEP 2`` from previous example to achieve the same
+functionality:
+
+.. code-block:: python
+
+ ['vswitch', 'del_port', 'int_br0', '#STEP[-1][0]'], # STEP 2
+
+Also commonly used steps can be created as a separate profile.
+
+.. code-block:: python
+
+ STEP_VSWITCH_PVP_INIT = [
+ ['vswitch', 'add_switch', 'int_br0'], # STEP 0
+ ['vswitch', 'add_phy_port', 'int_br0'], # STEP 1
+ ['vswitch', 'add_phy_port', 'int_br0'], # STEP 2
+ ['vswitch', 'add_vport', 'int_br0'], # STEP 3
+ ['vswitch', 'add_vport', 'int_br0'], # STEP 4
+ ]
+
+This profile can then be used inside other testcases
+
+.. code-block:: python
+
+ {
+ "Name": "vswitch_pvp",
+ "Deployment": "clean",
+ "Description": "vSwitch - configure switch and one vnf",

+HelloWorld and other basic Testcases
+------------------------------------
+
+The following examples are for demonstration purposes.
+You can run them by copying and pasting into the
+conf/integration/01_testcases.conf file.
+A command-line instruction is shown at the end of each
+example.
+
+HelloWorld
+^^^^^^^^^^
+
+The first example is a HelloWorld testcase.
+It simply creates a bridge with 2 physical ports, then sets up a flow to drop
+incoming packets from the port that was instantiated at the STEP #1.
+There's no interaction with the traffic generator.
+Then the flow, the 2 ports and the bridge are deleted.
+'add_phy_port' method creates a 'dpdk' type interface that will manage the
+physical port. The string value returned is the port name that will be referred
+by 'del_port' later on.
+
+.. code-block:: python

+ ['vswitch', 'del_switch', 'int_br0'],
+ ]
+
+ },
+
+To run HelloWorld test:
+
+ .. code-block:: console
+
+ ./vsperf --conf-file user_settings.py --integration HelloWorld
+
+Specify a Flow by the IP address
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The next example shows how to explicitly set up a flow by specifying a
+destination IP address.
+All packets received from the port created at STEP #1 that have a destination
+IP address = 90.90.90.90 will be forwarded to the port created at the STEP #2.
+
+.. code-block:: python

+To run the test:
+
+ .. code-block:: console

+
+Multistream feature
+^^^^^^^^^^^^^^^^^^^
+
+The next testcase uses the multistream feature.
+The traffic generator will send packets with different UDP ports.
+That is accomplished by using "Stream Type" and "MultiStream" keywords.
+4 different flows are set to forward all incoming packets.

+
+PVP with a VM Replacement
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This example launches a 1st VM in a PVP topology, then the VM is replaced
+by another VM.
+When VNF setup parameter in ./conf/04_vnf.conf is "QemuDpdkVhostUser"
+'add_vport' method creates a 'dpdkvhostuser' type port to connect a VM.

+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This is an example of modification of a standard deployment scenario with additional TestSteps.
+Standard PVVP scenario is used to configure a vSwitch and to deploy two VNFs connected

+already configured VNFs. Traffic generator is instructed (by Multistream feature) to send
+two separate traffic streams. One stream will be sent to the standalone VNF and second
+to two chained VNFs.
+
+In case, that test is defined as a performance test, then traffic results will be collected
+and available in both csv and rst report files.

+vSwitchPerf test suites userguide
+---------------------------------
+
+General
+^^^^^^^
+
+VSPERF requires a traffic generators to run tests, automated traffic gen
+support in VSPERF includes:
+
+- 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".
+- Xena Network traffic generator (Xena hardware chassis) that houses the Xena
+ Traffic generator modules.
+- Moongen software traffic generator. Requires a separate machine running
+ moongen to execute packet generation.
+
+If you want to use another traffic generator, please select the :ref:`trafficgen-dummy`
+generator.
+
+VSPERF Installation
+^^^^^^^^^^^^^^^^^^^
+
+To see the supported Operating Systems, vSwitches and system requirements,
+please follow the `installation instructions <vsperf-installation>`.
+
+Traffic Generator Setup
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Follow the `Traffic generator instructions <trafficgen-installation>` 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 stock OVS (without DPDK support). When build
+is finished, the libraries are stored in src_vanilla directory.
+
+The 'make' builds all options in src:
+
+* Vanilla OVS
+* OVS with vhost_user as the guest access method (with DPDK support)
+
+The vhost_user build will reside in src/ovs/
+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.
+
+Further details about configuration files evaluation and special behaviour
+of options with ``GUEST_`` prefix could be found at :ref:`design document
+<design-configuration>`.
+
+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_custom_conf> ...
+
+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. Testcase definition section ``Parameters``
+2. Command line arguments
+3. Environment variables
+4. Configuration file(s)
+
+Further details about configuration files evaluation and special behaviour
+of options with ``GUEST_`` prefix could be found at :ref:`design document
+<design-configuration>`.
+
+.. _overriding-parameters-documentation:
+
+Overriding values defined in configuration files
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The configuration items can be overridden by command line argument
+``--test-params``. In this case, the configuration items and
+their values should be passed in form of ``item=value`` and separated
+by semicolon.
+
+Example:
+
+.. code:: console
+
+ $ ./vsperf --test-params "TRAFFICGEN_DURATION=10;TRAFFICGEN_PKT_SIZES=(128,);" \
+ "GUEST_LOOPBACK=['testpmd','l2fwd']" pvvp_tput
+
+The second option is to override configuration items by ``Parameters`` section
+of the test case definition. The configuration items can be added into ``Parameters``
+dictionary with their new values. These values will override values defined in
+configuration files or specified by ``--test-params`` command line argument.
+
+Example:
+
+.. code:: python
+
+ "Parameters" : {'TRAFFICGEN_PKT_SIZES' : (128,),
+ 'TRAFFICGEN_DURATION' : 10,
+ 'GUEST_LOOPBACK' : ['testpmd','l2fwd'],
+ }
+
+**NOTE:** In both cases, configuration item names and their values must be specified
+in the same form as they are defined inside configuration files. Parameter names
+must be specified in uppercase and data types of original and new value must match.
+Python syntax rules related to data types and structures must be followed.
+For example, parameter ``TRAFFICGEN_PKT_SIZES`` above is defined as a tuple
+with a single value ``128``. In this case trailing comma is mandatory, otherwise
+value can be wrongly interpreted as a number instead of a tuple and vsperf
+execution would fail. Please check configuration files for default values and their
+types and use them as a basis for any customized values. In case of any doubt, please
+check official python documentation related to data structures like tuples, lists
+and dictionaries.
+
+**NOTE:** Vsperf execution will terminate with runtime error in case, that unknown
+parameter name is passed via ``--test-params`` CLI argument or defined in ``Parameters``
+section of test case definition. It is also forbidden to redefine a value of
+``TEST_PARAMS`` configuration item via CLI or ``Parameters`` section.
+
+vloop_vnf
+^^^^^^^^^
+
+VSPERF uses a VM image called vloop_vnf for looping traffic in the deployment
+scenarios involving VMs. The image can be downloaded from
+`<http://artifacts.opnfv.org/>`__.
+
+Please see the installation instructions for information on :ref:`vloop-vnf`
+images.
+
+.. _l2fwd-module:
+
+l2fwd Kernel Module
+^^^^^^^^^^^^^^^^^^^
+
+A Kernel Module that provides OSI Layer 2 Ipv4 termination or forwarding with
+support for Destination Network Address Translation (DNAT) for both the MAC and
+IP addresses. l2fwd can be found in <vswitchperf_dir>/src/l2fwd
+
+Executing tests
+^^^^^^^^^^^^^^^
+
+All examples inside these docs assume, that user is inside the VSPERF
+directory. VSPERF can be executed from any directory.
+
+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=<path_to_custom_conf>/10_custom.conf --tests="RFC2544"
+
+To run all tests:
+
+.. code-block:: console
+
+ $ ./vsperf --conf-file=<path_to_custom_conf>/10_custom.conf
+
+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-params "TRAFFICGEN_DURATION=10;TRAFFICGEN_PKT_SIZES=(128,)"
+
+For all available options, check out the help dialog:
+
+.. code-block:: console
+
+ $ ./vsperf --help
+
+Executing Vanilla OVS tests

+^^^^^^^^^^^^^^^^^^^^^^^^
+
+To run tests using vhost-user as guest access method:
+
+1. Set VHOST_METHOD and VNF of your settings file to:
+
+ .. code-block:: python
+
+ VSWITCH = 'OvsDpdkVhost'
+ VNF = 'QemuDpdkVhost'
+
+2. If needed, recompile src for all OVS variants

+ $ make
+
+3. Run test:
+
+ .. code-block:: console
+
+ $ ./vsperf --conf-file=<path_to_custom_conf>/10_custom.conf
+
+Executing tests with VMs using Vanilla OVS
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To run tests using Vanilla OVS:
+
+1. Set the following variables:
+
+ .. code-block:: python
+
+ VSWITCH = 'OvsVanilla'
+ VNF = 'QemuVirtioNet'
+
+ VANILLA_TGEN_PORT1_IP = n.n.n.n
+ VANILLA_TGEN_PORT1_MAC = nn:nn:nn:nn:nn:nn

+ .. code-block:: console
+
+ $ ./vsperf --conf-file<path_to_custom_conf>/10_custom.conf
+
+.. _vpp-test:
+
+Executing VPP tests
+^^^^^^^^^^^^^^^^^^^
+
+Currently it is not possible to use standard scenario deployments for execution of
+tests with VPP. It means, that deployments ``p2p``, ``pvp``, ``pvvp`` and in general any
+:ref:`pxp-deployment` won't work with VPP. However it is possible to use VPP in
+:ref:`step-driven-tests`. A basic set of VPP testcases covering ``phy2phy``, ``pvp``
+and ``pvvp`` tests are already prepared.
+
+List of performance tests with VPP support follows:
+
+* phy2phy_tput_vpp: VPP: LTD.Throughput.RFC2544.PacketLossRatio
+* phy2phy_cont_vpp: VPP: Phy2Phy Continuous Stream
+* phy2phy_back2back_vpp: VPP: LTD.Throughput.RFC2544.BackToBackFrames
+* pvp_tput_vpp: VPP: LTD.Throughput.RFC2544.PacketLossRatio
+* pvp_cont_vpp: VPP: PVP Continuous Stream
+* pvp_back2back_vpp: VPP: LTD.Throughput.RFC2544.BackToBackFrames
+* pvvp_tput_vpp: VPP: LTD.Throughput.RFC2544.PacketLossRatio
+* pvvp_cont_vpp: VPP: PVP Continuous Stream
+* pvvp_back2back_vpp: VPP: LTD.Throughput.RFC2544.BackToBackFrames
+
+In order to execute testcases with VPP it is required to:
+
+* install VPP manually, see :ref:`vpp-installation`
+* configure ``WHITELIST_NICS``, with two physical NICs connected to the traffic generator
+* configure traffic generator, see :ref:`trafficgen-installation`
+
+After that it is possible to execute VPP testcases listed above.
+
+For example:
+
+.. code-block:: console
+
+ $ ./vsperf --conf-file=<path_to_custom_conf> phy2phy_tput_vpp
+
+.. _vfio-pci:
+
+Using vfio_pci with DPDK
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To use vfio with DPDK instead of igb_uio add into your custom configuration
+file the following parameter:
+
+.. code-block:: python
+
+ PATHS['dpdk']['src']['modules'] = ['uio', 'vfio-pci']
+
+
+**NOTE:** In case, that DPDK is installed from binary package, then please
+set ``PATHS['dpdk']['bin']['modules']`` instead.
+
+**NOTE:** Please ensure that Intel VT-d is enabled in BIOS.
+
+**NOTE:** Please ensure your boot/grub parameters include
+the following:
+
+.. code-block:: console
+
+ iommu=pt intel_iommu=on
+
+To check that IOMMU is enabled on your platform:
+
+.. code-block:: console
+
+ $ dmesg | grep IOMMU
+ [ 0.000000] Intel-IOMMU: enabled
+ [ 0.139882] dmar: IOMMU 0: reg_base_addr fbffe000 ver 1:0 cap d2078c106f0466 ecap f020de
+ [ 0.139888] dmar: IOMMU 1: reg_base_addr ebffc000 ver 1:0 cap d2078c106f0466 ecap f020de
+ [ 0.139893] IOAPIC id 2 under DRHD base 0xfbffe000 IOMMU 0
+ [ 0.139894] IOAPIC id 0 under DRHD base 0xebffc000 IOMMU 1
+ [ 0.139895] IOAPIC id 1 under DRHD base 0xebffc000 IOMMU 1
+ [ 3.335744] IOMMU: dmar0 using Queued invalidation
+ [ 3.335746] IOMMU: dmar1 using Queued invalidation
+ ....
+
+.. _SRIOV-support:
+
+Using SRIOV support
+^^^^^^^^^^^^^^^^^^^
+
+To use virtual functions of NIC with SRIOV support, use extended form
+of NIC PCI slot definition:
+
+.. code-block:: python
+
+ WHITELIST_NICS = ['0000:05:00.0|vf0', '0000:05:00.1|vf3']
+
+Where 'vf' is an indication of virtual function usage and following
+number defines a VF to be used. In case that VF usage is detected,
+then vswitchperf will enable SRIOV support for given card and it will
+detect PCI slot numbers of selected VFs.
+
+So in example above, one VF will be configured for NIC '0000:05:00.0'
+and four VFs will be configured for NIC '0000:05:00.1'. Vswitchperf
+will detect PCI addresses of selected VFs and it will use them during
+test execution.
+
+At the end of vswitchperf execution, SRIOV support will be disabled.
+
+SRIOV support is generic and it can be used in different testing scenarios.
+For example:
+
+* vSwitch tests with DPDK or without DPDK support to verify impact
+ of VF usage on vSwitch performance
+* tests without vSwitch, where traffic is forwared directly
+ between VF interfaces by packet forwarder (e.g. testpmd application)
+* tests without vSwitch, where VM accesses VF interfaces directly
+ by PCI-passthrough_ to measure raw VM throughput performance.
+
+.. _PCI-passthrough:
+
+Using QEMU with PCI passthrough support
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Raw virtual machine throughput performance can be measured by execution of PVP
+test with direct access to NICs by PCI passthrough. To execute VM with direct
+access to PCI devices, enable vfio-pci_. In order to use virtual functions,
+SRIOV-support_ must be enabled.
+
+Execution of test with PCI passthrough with vswitch disabled:
+
+.. code-block:: console
+
+ $ ./vsperf --conf-file=<path_to_custom_conf>/10_custom.conf \
+ --vswitch none --vnf QemuPciPassthrough pvp_tput
+
+Any of supported guest-loopback-application_ can be used inside VM with
+PCI passthrough support.
+
+Note: Qemu with PCI passthrough support can be used only with PVP test
+deployment.
+
+.. _guest-loopback-application:
+
+Selection of loopback application for tests with VMs
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To select the loopback applications which will forward packets inside VMs,
+the following parameter should be configured:
+
+.. code-block:: python
+
+ GUEST_LOOPBACK = ['testpmd']
+
+or use ``--test-params`` CLI argument:
+
+.. code-block:: console
+
+ $ ./vsperf --conf-file=<path_to_custom_conf>/10_custom.conf \
+ --test-params "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 VM related deployments
+will fail. Guest loopback application is set to 'testpmd' by default.
+
+**NOTE:** In case that only 1 or more than 2 NICs are configured for VM,
+then 'testpmd' should be used. As it is able to forward traffic between
+multiple VM NIC pairs.
+
+**NOTE:** In case of linux_bridge, all guest NICs are connected to the same
+bridge inside the guest.
+
+Mergable Buffers Options with QEMU
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Mergable buffers can be disabled with VSPerf within QEMU. This option can
+increase performance significantly when not using jumbo frame sized packets.
+By default VSPerf disables mergable buffers. If you wish to enable it you
+can modify the setting in the a custom conf file.
+
+.. code-block:: python
+
+ GUEST_NIC_MERGE_BUFFERS_DISABLE = [False]
+
+Then execute using the custom conf file.
+
+.. code-block:: console
+
+ $ ./vsperf --conf-file=<path_to_custom_conf>/10_custom.conf
+
+Alternatively you can just pass the param during execution.
+
+.. code-block:: console
+
+ $ ./vsperf --test-params "GUEST_NIC_MERGE_BUFFERS_DISABLE=[False]"
+
+
+Selection of dpdk binding driver for tests with VMs
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To select dpdk binding driver, which will specify which driver the vm NICs will
+use for dpdk bind, the following configuration parameter should be configured:
+
+.. code-block:: console
+
+ GUEST_DPDK_BIND_DRIVER = ['igb_uio_from_src']
+
+The supported dpdk guest bind drivers are:
+
+.. code-block:: console
+
+ 'uio_pci_generic' - Use uio_pci_generic driver
+ 'igb_uio_from_src' - Build and use the igb_uio driver from the dpdk src
+ files
+ 'vfio_no_iommu' - Use vfio with no iommu option. This requires custom
+ guest images that support this option. The default
+ vloop image does not support this driver.
+
+Note: uio_pci_generic does not support sr-iov testcases with guests attached.
+This is because uio_pci_generic only supports legacy interrupts. In case
+uio_pci_generic is selected with the vnf as QemuPciPassthrough it will be
+modified to use igb_uio_from_src instead.
+
+Note: vfio_no_iommu requires kernels equal to or greater than 4.5 and dpdk
+16.04 or greater. Using this option will also taint the kernel.
+
+Please refer to the dpdk documents at http://dpdk.org/doc/guides for more
+information on these drivers.
+
+Multi-Queue Configuration
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+VSPerf currently supports multi-queue with the following limitations:
+
+1. Requires QEMU 2.5 or greater and any OVS version higher than 2.5. The
+ default upstream package versions installed by VSPerf satisfies this
+ requirement.
+
+2. Guest image must have ethtool utility installed if using l2fwd or linux
+ bridge inside guest for loopback.
+
+3. If using OVS versions 2.5.0 or less enable old style multi-queue as shown
+ in the ''02_vswitch.conf'' file.
+
+ .. code-block:: python
+
+ OVS_OLD_STYLE_MQ = True
+
+To enable multi-queue for dpdk modify the ''02_vswitch.conf'' file.
+
+.. code-block:: python
+
+ VSWITCH_DPDK_MULTI_QUEUES = 2
+
+**NOTE:** you should consider using the switch affinity to set a pmd cpu mask
+that can optimize your performance. Consider the numa of the NIC in use if this
+applies by checking /sys/class/net/<eth_name>/device/numa_node and setting an
+appropriate mask to create PMD threads on the same numa node.
+
+When multi-queue is enabled, each dpdk or dpdkvhostuser port that is created
+on the switch will set the option for multiple queues. If old style multi queue
+has been enabled a global option for multi queue will be used instead of the
+port by port option.
+
+To enable multi-queue on the guest modify the ''04_vnf.conf'' file.
+
+.. code-block:: python
+
+ GUEST_NIC_QUEUES = [2]
+
+Enabling multi-queue at the guest will add multiple queues to each NIC port when
+qemu launches the guest.
+
+In case of Vanilla OVS, multi-queue is enabled on the tuntap ports and nic
+queues will be enabled inside the guest with ethtool. Simply enabling the
+multi-queue on the guest is sufficient for Vanilla OVS multi-queue.
+
+Testpmd should be configured to take advantage of multi-queue on the guest if
+using DPDKVhostUser. This can be done by modifying the ''04_vnf.conf'' file.
+
+.. code-block:: python
+
+ GUEST_TESTPMD_PARAMS = ['-l 0,1,2,3,4 -n 4 --socket-mem 512 -- '
+ '--burst=64 -i --txqflags=0xf00 '
+ '--nb-cores=4 --rxq=2 --txq=2 '
+ '--disable-hw-vlan']
+
+**NOTE:** The guest SMP cores must be configured to allow for testpmd to use the
+optimal number of cores to take advantage of the multiple guest queues.
+
+In case of using Vanilla OVS and qemu virtio-net you can increase performance
+by binding vhost-net threads to cpus. This can be done by enabling the affinity
+in the ''04_vnf.conf'' file. This can be done to non multi-queue enabled
+configurations as well as there will be 2 vhost-net threads.
+
+.. code-block:: python
+
+ VSWITCH_VHOST_NET_AFFINITIZATION = True
+
+ VSWITCH_VHOST_CPU_MAP = [4,5,8,11]
+
+**NOTE:** This method of binding would require a custom script in a real
+environment.
+
+**NOTE:** For optimal performance guest SMPs and/or vhost-net threads should be
+on the same numa as the NIC in use if possible/applicable. Testpmd should be
+assigned at least (nb_cores +1) total cores with the cpu mask.
+
+Executing Packet Forwarding tests
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To select the applications which will forward packets,
+the following parameters should be configured:
+
+.. code-block:: python
+
+ VSWITCH = 'none'
+ PKTFWD = 'TestPMD'
+
+or use ``--vswitch`` and ``--fwdapp`` CLI arguments:
+
+.. code-block:: console
+
+ $ ./vsperf phy2phy_cont --conf-file user_settings.py \
+ --vswitch none \
+ --fwdapp TestPMD
+
+Supported Packet Forwarding applications are:
+
+.. code-block:: console
+
+ 'testpmd' - testpmd from dpdk
+
+
+1. Update your ''10_custom.conf'' file to use the appropriate variables
+ for selected Packet Forwarder:
+
+ .. code-block:: python
+
+ # testpmd configuration
+ TESTPMD_ARGS = []
+ # packet forwarding mode supported by testpmd; Please see DPDK documentation
+ # for comprehensive list of modes supported by your version.
+ # e.g. io|mac|mac_retry|macswap|flowgen|rxonly|txonly|csum|icmpecho|...
+ # Note: Option "mac_retry" has been changed to "mac retry" since DPDK v16.07
+ TESTPMD_FWD_MODE = 'csum'
+ # checksum calculation layer: ip|udp|tcp|sctp|outer-ip
+ TESTPMD_CSUM_LAYER = 'ip'
+ # checksum calculation place: hw (hardware) | sw (software)
+ TESTPMD_CSUM_CALC = 'sw'
+ # recognize tunnel headers: on|off
+ TESTPMD_CSUM_PARSE_TUNNEL = 'off'
+
+2. Run test:
+
+ .. code-block:: console
+
+ $ ./vsperf phy2phy_tput --conf-file <path_to_settings_py>
+
+Executing Packet Forwarding tests with one guest
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+TestPMD with DPDK 16.11 or greater can be used to forward packets as a switch to a single guest using TestPMD vdev
+option. To set this configuration the following parameters should be used.
+
+ .. code-block:: python
+
+ VSWITCH = 'none'
+ PKTFWD = 'TestPMD'
+
+or use ``--vswitch`` and ``--fwdapp`` CLI arguments:
+
+ .. code-block:: console
+
+ $ ./vsperf pvp_tput --conf-file user_settings.py \
+ --vswitch none \
+ --fwdapp TestPMD
+
+Guest forwarding application only supports TestPMD in this configuration.
+
+ .. code-block:: python
+
+ GUEST_LOOPBACK = ['testpmd']
+
+For optimal performance one cpu per port +1 should be used for TestPMD. Also set additional params for packet forwarding
+application to use the correct number of nb-cores.
+
+ .. code-block:: python
+
+ DPDK_SOCKET_MEM = ['1024', '0']
+ VSWITCHD_DPDK_ARGS = ['-l', '46,44,42,40,38', '-n', '4']
+ TESTPMD_ARGS = ['--nb-cores=4', '--txq=1', '--rxq=1']
+
+For guest TestPMD 3 VCpus should be assigned with the following TestPMD params.
+
+ .. code-block:: python
+
+ GUEST_TESTPMD_PARAMS = ['-l 0,1,2 -n 4 --socket-mem 1024 -- '
+ '--burst=64 -i --txqflags=0xf00 '
+ '--disable-hw-vlan --nb-cores=2 --txq=1 --rxq=1']
+
+Execution of TestPMD can be run with the following command line
+
+ .. code-block:: console
+
+ ./vsperf pvp_tput --vswitch=none --fwdapp=TestPMD --conf-file <path_to_settings_py>
+
+**NOTE:** To achieve the best 0% loss numbers with rfc2544 throughput testing, other tunings should be applied to host
+and guest such as tuned profiles and CPU tunings to prevent possible interrupts to worker threads.
+
+VSPERF modes of operation
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+VSPERF can be run in different modes. By default it will configure vSwitch,
+traffic generator and VNF. However it can be used just for configuration
+and execution of traffic generator. Another option is execution of all
+components except traffic generator itself.
+
+Mode of operation is driven by configuration parameter -m or --mode
+
+.. code-block:: console
+
+ -m MODE, --mode MODE vsperf mode of operation;
+ Values:
+ "normal" - execute vSwitch, VNF and traffic generator
+ "trafficgen" - execute only traffic generator
+ "trafficgen-off" - execute vSwitch and VNF
+ "trafficgen-pause" - execute vSwitch and VNF but wait before traffic transmission
+
+In case, that VSPERF is executed in "trafficgen" mode, then configuration
+of traffic generator can be modified through ``TRAFFIC`` dictionary passed to the
+``--test-params`` option. It is not needed to specify all values of ``TRAFFIC``
+dictionary. It is sufficient to specify only values, which should be changed.
+Detailed description of ``TRAFFIC`` dictionary can be found at
+:ref:`configuration-of-traffic-dictionary`.
+
+Example of execution of VSPERF in "trafficgen" mode:
+
+.. code-block:: console
+
+ $ ./vsperf -m trafficgen --trafficgen IxNet --conf-file vsperf.conf \
+ --test-params "TRAFFIC={'traffic_type':'rfc2544_continuous','bidir':'False','framerate':60}"
+
+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:
+^^^^^^^^
+
+Custom image fails to boot
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Using custom VM images may not boot within VSPerf pxp testing because of
+the drive boot and shared type which could be caused by a missing scsi
+driver inside the image. In case of issues you can try changing the drive
+boot type to ide.
+
+.. code-block:: python
+
+ GUEST_BOOT_DRIVE_TYPE = ['ide']
+ GUEST_SHARED_DRIVE_TYPE = ['ide']
+
+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" during qemu initialization,
+check the amount of hugepages on your system:
+
+.. code-block:: console
+
+ $ 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-block:: python
+
+ DPDK_SOCKET_MEM = ['1024', '0']
+ VSWITCHD_DPDK_ARGS = ['-c', '0x4', '-n', '4']
+ VSWITCHD_DPDK_CONFIG = {
+ 'dpdk-init' : 'true',
+ 'dpdk-lcore-mask' : '0x4',
+ 'dpdk-socket-mem' : '1024,0',
+ }
+
+Note: Option ``VSWITCHD_DPDK_ARGS`` is used for vswitchd, which supports ``--dpdk``
+parameter. In recent vswitchd versions, option ``VSWITCHD_DPDK_CONFIG`` will be
+used to configure vswitchd via ``ovs-vsctl`` calls.

+Execution of vswitchperf testcases by Yardstick
+-----------------------------------------------
+
+General
+^^^^^^^
+
+Yardstick is a generic framework for a test execution, which is used for
+validation of installation of OPNFV platform. In the future, Yardstick will
+support two options of vswitchperf testcase execution:
+
+- plugin mode, which will execute native vswitchperf testcases; Tests will
+ be executed natively by vsperf, and test results will be processed and
+ reported by yardstick.
+- traffic generator mode, which will run vswitchperf in **trafficgen**
+ mode only; Yardstick framework will be used to launch VNFs and to configure
+ flows to ensure, that traffic is properly routed. This mode will allow to
+ test OVS performance in real world scenarios.
+
+In Colorado release only the traffic generator mode is supported.
+
+Yardstick Installation
+^^^^^^^^^^^^^^^^^^^^^^
+
+In order to run Yardstick testcases, you will need to prepare your test
+environment. Please follow the `installation instructions
+<http://artifacts.opnfv.org/yardstick/docs/user_guides_framework/index.html>`__
+to install the yardstick.
+
+Please note, that yardstick uses OpenStack for execution of testcases.
+OpenStack must be installed with Heat and Neutron services. Otherwise
+vswitchperf testcases cannot be executed.
+
+VM image with vswitchperf
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+A special VM image is required for execution of vswitchperf specific testcases
+by yardstick. It is possible to use a sample VM image available at OPNFV
+artifactory or to build customized image.
+
+Sample VM image with vswitchperf
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Sample VM image is available at vswitchperf section of OPNFV artifactory
+for free download:
+
+.. code-block:: console
+
+ $ wget http://artifacts.opnfv.org/vswitchperf/vnf/vsperf-yardstick-image.qcow2
+
+This image can be used for execution of sample testcases with dummy traffic
+generator.
+
+**NOTE:** Traffic generators might require an installation of client software.
+This software is not included in the sample image and must be installed by user.
+
+**NOTE:** This image will be updated only in case, that new features related
+to yardstick integration will be added to the vswitchperf.
+
+Preparation of custom VM image
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In general, any Linux distribution supported by vswitchperf can be used as
+a base image for vswitchperf. One of the possibilities is to modify vloop-vnf
+image, which can be downloaded from `<http://artifacts.opnfv.org/vswitchperf.html/>`__
+(see :ref:`vloop-vnf`).
+
+Please follow the :ref:`vsperf-installation` to
+install vswitchperf inside vloop-vnf image. As vswitchperf will be run in
+trafficgen mode, it is possible to skip installation and compilation of OVS,
+QEMU and DPDK to keep image size smaller.
+
+In case, that selected traffic generator requires installation of additional
+client software, please follow appropriate documentation. For example in case
+of IXIA, you would need to install IxOS and IxNetowrk TCL API.
+
+VM image usage
+~~~~~~~~~~~~~~
+
+Image with vswitchperf must be uploaded into the glance service and
+vswitchperf specific flavor configured, e.g.:
+
+.. code-block:: console
+
+ $ glance --os-username admin --os-image-api-version 1 image-create --name \
+ vsperf --is-public true --disk-format qcow2 --container-format bare --file \
+ vsperf-yardstick-image.qcow2
+
+ $ nova --os-username admin flavor-create vsperf-flavor 100 2048 25 1
+
+Testcase execution
+^^^^^^^^^^^^^^^^^^
+
+After installation, yardstick is available as python package within yardstick
+specific virtual environment. It means, that yardstick environment must be
+enabled before the test execution, e.g.:
+
+.. code-block:: console
+
+ source ~/yardstick_venv/bin/activate
+
+
+Next step is configuration of OpenStack environment, e.g. in case of devstack:
+
+.. code-block:: console
+
+ source /opt/openstack/devstack/openrc
+ export EXTERNAL_NETWORK=public
+
+Vswitchperf testcases executable by yardstick are located at vswitchperf
+repository inside ``yardstick/tests`` directory. Example of their download
+and execution follows:
+
+.. code-block:: console
+
+ git clone https://gerrit.opnfv.org/gerrit/vswitchperf
+ cd vswitchperf
+
+ yardstick -d task start yardstick/tests/rfc2544_throughput_dummy.yaml
+
+**NOTE:** Optional argument ``-d`` shows debug output.
+
+Testcase customization
+^^^^^^^^^^^^^^^^^^^^^^
+
+Yardstick testcases are described by YAML files. vswitchperf specific testcases
+are part of the vswitchperf repository and their yaml files can be found at
+``yardstick/tests`` directory. For detailed description of yaml file structure,
+please see yardstick documentation and testcase samples. Only vswitchperf specific
+parts will be discussed here.
+
+Example of yaml file:
+
+.. code-block:: yaml
+
+ ...
+ scenarios:
+ -
+ type: Vsperf
+ options:
+ testname: 'p2p_rfc2544_throughput'
+ trafficgen_port1: 'eth1'
+ trafficgen_port2: 'eth3'
+ external_bridge: 'br-ex'
+ test_params: 'TRAFFICGEN_DURATION=30;TRAFFIC={'traffic_type':'rfc2544_throughput}'
+ conf_file: '~/vsperf-yardstick.conf'
+
+ host: vsperf.demo
+
+ runner:
+ type: Sequence
+ scenario_option_name: frame_size
+ sequence:
+ - 64
+ - 128
+ - 512
+ - 1024
+ - 1518
+ sla:
+ metrics: 'throughput_rx_fps'
+ throughput_rx_fps: 500000
+ action: monitor
+
+ context:
+ ...
+
+Section option
+~~~~~~~~~~~~~~
+
+Section **option** defines details of vswitchperf test scenario. Lot of options
+are identical to the vswitchperf parameters passed through ``--test-params``
+argument. Following options are supported:
+
+- **frame_size** - a packet size for which test should be executed;
+ Multiple packet sizes can be tested by modification of Sequence runner
+ section inside YAML definition. Default: '64'
+- **conf_file** - sets path to the vswitchperf configuration file, which will be
+ uploaded to VM; Default: '~/vsperf-yardstick.conf'
+- **setup_script** - sets path to the setup script, which will be executed
+ during setup and teardown phases
+- **trafficgen_port1** - specifies device name of 1st interface connected to
+ the trafficgen
+- **trafficgen_port2** - specifies device name of 2nd interface connected to
+ the trafficgen
+- **external_bridge** - specifies name of external bridge configured in OVS;
+ Default: 'br-ex'
+- **test_params** - specifies a string with a list of vsperf configuration
+ parameters, which will be passed to the ``--test-params`` CLI argument;
+ Parameters should be stated in the form of ``param=value`` and separated
+ by a semicolon. Configuration of traffic generator is driven by ``TRAFFIC``
+ dictionary, which can be also updated by values defined by ``test_params``.
+ Please check VSPERF documentation for details about available configuration
+ parameters and their data types.
+ In case that both **test_params** and **conf_file** are specified,
+ then values from **test_params** will override values defined
+ in the configuration file.
+
+In case that **trafficgen_port1** and/or **trafficgen_port2** are defined, then
+these interfaces will be inserted into the **external_bridge** of OVS. It is
+expected, that OVS runs at the same node, where the testcase is executed. In case
+of more complex OpenStack installation or a need of additional OVS configuration,
+**setup_script** can be used.
+
+**NOTE** It is essential to specify a configuration for selected traffic generator.
+In case, that standalone testcase is created, then traffic generator can be
+selected and configured directly in YAML file by **test_params**. On the other
+hand, if multiple testcases should be executed with the same traffic generator
+settings, then a customized configuration file should be prepared and its name
+passed by **conf_file** option.
+
+Section runner
+~~~~~~~~~~~~~~
+
+Yardstick supports several `runner types
+<http://artifacts.opnfv.org/yardstick/docs/userguide/architecture.html#runner-types>`__.
+In case of vswitchperf specific TCs, **Sequence** runner type can be used to
+execute the testcase for given list of frame sizes.
+
+
+Section sla
+~~~~~~~~~~~
+
+In case that sla section is not defined, then testcase will be always
+considered as successful. On the other hand, it is possible to define a set of
+test metrics and their minimal values to evaluate test success. Any numeric
+value, reported by vswitchperf inside CSV result file, can be used.
+Multiple metrics can be defined as a coma separated list of items. Minimal
+value must be set separately for each metric.
+
+e.g.:
+
+.. code-block:: yaml
+
+ sla:
+ metrics: 'throughput_rx_fps,throughput_rx_mbps'
+ throughput_rx_fps: 500000
+ throughput_rx_mbps: 1000
+
+In case that any of defined metrics will be lower than defined value, then
+testcase will be marked as failed. Based on ``action`` policy, yardstick
+will either stop test execution (value ``assert``) or it will run next test
+(value ``monitor``).
+
+**NOTE** The throughput SLA (or any other SLA) cannot be set to a meaningful
+value without knowledge of the server and networking environment, possibly
+including prior testing in that environment to establish a baseline SLA level
+under well-understood circumstances.
