+Yardstick - NSB Testing -Installation
+=====================================
+
+Abstract
+--------
+
+The Network Service Benchmarking (NSB) extends the yardstick framework to do
+VNF characterization and benchmarking in three different execution
+environments viz., bare metal i.e. native Linux environment, standalone virtual
+environment and managed virtualized environment (e.g. Open stack etc.).
+It also brings in the capability to interact with external traffic generators
+both hardware & software based for triggering and validating the traffic
+according to user defined profiles.
+
+The steps needed to run Yardstick with NSB testing are:
+
+* Install Yardstick (NSB Testing).
+* Setup/Reference pod.yaml describing Test topology
+* Create/Reference the test configuration yaml file.
+* Run the test case.
+
+

+
+  .. code-block:: console
+
+      brctl addbr br-int
+      brctl addif br-int <interface_name>    #This interface is connected to internet
+
+ b) Build guest image for VNF to run.
+    Most of the sample test cases in Yardstick are using a guest image called
+    ``yardstick-image`` which deviates from an Ubuntu Cloud Server image
+    Yardstick has a tool for building this custom image with samplevnf.
+    It is necessary to have ``sudo`` rights to use this tool.
+
+    Also you may need to install several additional packages to use this tool, by
+    following the commands below::
+
+       sudo apt-get update && sudo apt-get install -y qemu-utils kpartx
+
+    This image can be built using the following command in the directory where Yardstick is installed
+
+    .. code-block:: console
+
+       export YARD_IMG_ARCH='amd64'
+       sudo echo "Defaults env_keep += \'YARD_IMG_ARCH\'" >> /etc/sudoers
+
+    Please use ansible script to generate a cloud image refer to :doc:`04-installation`
+
+    for more details refer to chapter :doc:`04-installation`
+
+    .. note:: VM should be build with static IP and should be accessible from yardstick host.

+ a) Create a bridge for VM to connect to external network
+
+  .. code-block:: console
+
+      brctl addbr br-int
+      brctl addif br-int <interface_name>    #This interface is connected to internet
+
+ b) Build guest image for VNF to run.
+    Most of the sample test cases in Yardstick are using a guest image called
+    ``yardstick-image`` which deviates from an Ubuntu Cloud Server image
+    Yardstick has a tool for building this custom image with samplevnf.

+    Also you may need to install several additional packages to use this tool, by
+    following the commands below::
+
+       sudo apt-get update && sudo apt-get install -y qemu-utils kpartx
+
+    This image can be built using the following command in the directory where Yardstick is installed::
+
+       export YARD_IMG_ARCH='amd64'
+       sudo echo "Defaults env_keep += \'YARD_IMG_ARCH\'" >> /etc/sudoers

+
+    for more details refer to chapter :doc:`04-installation`
+
+    .. note::  VM should be build with static IP and should be accessible from yardstick host.
+
+ c) OVS & DPDK version.
+     - OVS 2.7 and DPDK 16.11.1 above version is supported
+
+ d) Setup OVS/DPDK on host.

+IxLoad:
+^^^^^^^
+
+1. Software needed: IxLoadAPI ``<IxLoadTclApi verson>Linux64.bin.tgz and <IxOS version>Linux64.bin.tar.gz`` (Download from ixia support site)
+                     Install - ``<IxLoadTclApi verson>Linux64.bin.tgz & <IxOS version>Linux64.bin.tar.gz``
+   If the installation was not done inside the container, after installing the IXIA client,
+   check /opt/ixia/ixload/<ver>/bin/ixloadpython and make sure you can run this cmd
+   inside the yardstick container. Usually user is required to copy or link /opt/ixia/python/<ver>/bin/ixiapython
+   to /usr/bin/ixiapython<ver> inside the container.

+
+Yardstick - NSB Testing - Operation
+===================================
+
+Abstract
+--------
+
+NSB test configuration and OpenStack setup requirements
+
+
+OpenStack Network Configuration
+-------------------------------
+
+NSB requires certain OpenStack deployment configurations.
+For optimal VNF characterization using external traffic generators NSB requires
+provider/external networks.
+
+
+Provider networks
+^^^^^^^^^^^^^^^^^
+
+The VNFs require a clear L2 connect to the external network in order to generate
+realistic traffic from multiple address ranges and port
+
+In order to prevent Neutron from filtering traffic we have to disable Neutron Port Security.
+We also disable DHCP on the data ports because we are binding the ports to DPDK and do not need
+DHCP addresses.  We also disable gateways because multiple default gateways can prevent SSH access
+to the VNF from the floating IP.  We only want a gateway on the mgmt network
+
+.. code-block:: yaml
+
+    uplink_0:
+      cidr: '10.1.0.0/24'
+      gateway_ip: 'null'
+      port_security_enabled: False
+      enable_dhcp: 'false'
+
+Heat Topologies
+^^^^^^^^^^^^^^^
+
+By default Heat will attach every node to every Neutron network that is created.
+For scale-out tests we do not want to attach every node to every network.
+
+For each node you can specify which ports are on which network using the
+network_ports dictionary.
+
+In this example we have ``TRex xe0 <-> xe0 VNF xe1 <-> xe0 UDP_Replay``
+
+.. code-block:: yaml
+
+      vnf_0:
+        floating_ip: true
+        placement: "pgrp1"
+        network_ports:
+          mgmt:
+            - mgmt
+          uplink_0:
+            - xe0
+          downlink_0:
+            - xe1
+      tg_0:
+        floating_ip: true
+        placement: "pgrp1"
+        network_ports:
+          mgmt:
+            - mgmt
+          uplink_0:
+            - xe0
+          # Trex always needs two ports
+          uplink_1:
+            - xe1
+      tg_1:
+        floating_ip: true
+        placement: "pgrp1"
+        network_ports:
+          mgmt:
+           - mgmt
+          downlink_0:
+           - xe0
+
+Collectd KPIs
+-------------
+
+NSB can collect KPIs from collected.  We have support for various plugins enabled by the
+Barometer project.
+
+The default yardstick-samplevnf has collectd installed.   This allows for collecting KPIs
+from the VNF.
+
+Collecting KPIs from the NFVi is more complicated and requires manual setup.
+We assume that collectd is not installed on the compute nodes.
+
+To collectd KPIs from the NFVi compute nodes:
+
+
+    * install_collectd on the compute nodes
+    * create pod.yaml for the compute nodes
+    * enable specific plugins depending on the vswitch and DPDK
+
+    example pod.yaml section for Compute node running collectd.
+
+.. code-block:: yaml
+
+    -
+      name: "compute-1"
+      role: Compute
+      ip: "10.1.2.3"
+      user: "root"
+      ssh_port: "22"
+      password: ""
+      collectd:
+        interval: 5
+        plugins:
+          # for libvirtd stats
+          virt: {}
+          intel_pmu: {}
+          ovs_stats:
+            # path to OVS socket
+            ovs_socket_path: /var/run/openvswitch/db.sock
+          intel_rdt: {}
+
+
+
+Scale-Up
+------------------
+
+VNFs performance data with scale-up
+
+  * Helps to figure out optimal number of cores specification in the Virtual Machine template creation or VNF
+  * Helps in comparison between different VNF vendor offerings
+  * Better the scale-up index, indicates the performance scalability of a particular solution
+
+Heat
+^^^^
+
+For VNF scale-up tests we increase the number for VNF worker threads.  In the case of VNFs
+we also need to increase the number of VCPUs and memory allocated to the VNF.
+
+An example scale-up Heat testcase is:
+
+.. code-block:: console
+
+  <repo>/samples/vnf_samples/nsut/acl/tc_heat_rfc2544_ipv4_1rule_1flow_64B_trex_scale_up.yaml
+
+This testcase template requires specifying the number of VCPUs and Memory.
+We set the VCPUs and memory using the --task-args options
+
+.. code-block:: console
+
+  yardstick --debug task start --task-args='{"mem": 20480, "vcpus": 10}'   samples/vnf_samples/nsut/acl/tc_heat_rfc2544_ipv4_1rule_1flow_64B_trex_scale_up.yaml
+
+
+Baremetal
+^^^^^^^^^
+  1. Follow above traffic generator section to setup.
+  2. edit num of threads in ``<repo>/samples/vnf_samples/nsut/vfw/tc_baremetal_rfc2544_ipv4_1rule_1flow_64B_trex_scale_up.yaml``
+
+  e.g, 6 Threads  for given VNF
+
+.. code-block:: yaml
+
+
+     schema: yardstick:task:0.1
+     scenarios:
+     {% for worker_thread in [1, 2 ,3 , 4, 5, 6] %}
+     - type: NSPerf
+       traffic_profile: ../../traffic_profiles/ipv4_throughput.yaml
+       topology: vfw-tg-topology.yaml
+       nodes:
+         tg__0: trafficgen_1.yardstick
+         vnf__0: vnf.yardstick
+       options:
+         framesize:
+           uplink: {64B: 100}
+           downlink: {64B: 100}
+         flow:
+           src_ip: [{'tg__0': 'xe0'}]
+           dst_ip: [{'tg__0': 'xe1'}]
+           count: 1

+           vnf_config: {lb_config: 'HW', lb_count: 1, worker_config: '1C/1T', worker_threads: {{worker_thread}}}
+           nfvi_enable: True
+       runner:
+         type: Iteration
+         iterations: 10
+         interval: 35
+     {% endfor %}
+     context:
+       type: Node
+       name: yardstick
+       nfvi_type: baremetal
+       file: /etc/yardstick/nodes/pod.yaml
+
+Scale-Out
+--------------------
+
+VNFs performance data with scale-out
+
+  * Helps in capacity planning to meet the given network node requirements
+  * Helps in comparison between different VNF vendor offerings
+  * Better the scale-out index, provides the flexibility in meeting future capacity requirements
+
+
+Standalone
+^^^^^^^^^^
+
+Scale-out not supported on Baremetal.
+
+1. Follow above traffic generator section to setup.
+2. Generate testcase for standalone virtualization using ansible scripts
+
+  .. code-block:: console
+
+    cd <repo>/ansible
+    trex: standalone_ovs_scale_out_trex_test.yaml or standalone_sriov_scale_out_trex_test.yaml
+    ixia: standalone_ovs_scale_out_ixia_test.yaml or standalone_sriov_scale_out_ixia_test.yaml
+    ixia_correlated: standalone_ovs_scale_out_ixia_correlated_test.yaml or standalone_sriov_scale_out_ixia_correlated_test.yaml
+
+  update the ovs_dpdk or sriov above Ansible scripts reflect the setup
+
+3. run the test
+
+  .. code-block:: console
+
+    <repo>/samples/vnf_samples/nsut/tc_sriov_vfw_udp_ixia_correlated_scale_out-1.yaml
+    <repo>/samples/vnf_samples/nsut/tc_sriov_vfw_udp_ixia_correlated_scale_out-2.yaml
+
+Heat
+^^^^
+
+There are sample scale-out all-VM Heat tests.  These tests only use VMs and don't use external traffic.
+
+The tests use UDP_Replay and correlated traffic.
+
+.. code-block:: console
+
+  <repo>/samples/vnf_samples/nsut/cgnapt/tc_heat_rfc2544_ipv4_1flow_64B_trex_correlated_scale_4.yaml
+
+To run the test you need to increase OpenStack CPU, Memory and Port quotas.
+
+
+Traffic Generator tuning
+------------------------
+
+The TRex traffic generator can be setup to use multiple threads per core, this is for multiqueue testing.
+
+TRex does not automatically enable multiple threads because we currently cannot detect the number of queues on a device.
+
+To enable multiple queue set the queues_per_port value in the TG VNF options section.
+
+.. code-block:: yaml
+
+  scenarios:
+    - type: NSPerf
+      nodes:
+        tg__0: tg_0.yardstick
+
+      options:
+        tg_0:
+          queues_per_port: 2

-Yardstick - NSB Testing -Installation
-=====================================
-
-Abstract
---------
-
-The Network Service Benchmarking (NSB) extends the yardstick framework to do
-VNF characterization and benchmarking in three different execution
-environments viz., bare metal i.e. native Linux environment, standalone virtual
-environment and managed virtualized environment (e.g. Open stack etc.).
-It also brings in the capability to interact with external traffic generators
-both hardware & software based for triggering and validating the traffic
-according to user defined profiles.
-
-The steps needed to run Yardstick with NSB testing are:
-
-* Install Yardstick (NSB Testing).
-* Setup pod.yaml describing Test topology
-* Create the test configuration yaml file.
-* Run the test case.
-

-Using Docker
-------------
-Refer chapter :doc:`04-installation` for more on docker **Install Yardstick using Docker (**recommended**)**
-
-Install directly in Ubuntu
---------------------------
-.. _install-framework:
-
-Alternatively you can install Yardstick framework directly in Ubuntu or in an Ubuntu Docker image. No matter which way you choose to install Yardstick, the following installation steps are identical.
-
-If you choose to use the Ubuntu Docker image, you can pull the Ubuntu
-Docker image from Docker hub::
-
-  docker pull ubuntu:16.04
-
-Install Yardstick
-^^^^^^^^^^^^^^^^^^^^^
-
-Prerequisite preparation::
-
-  apt-get update && apt-get install -y git python-setuptools python-pip
-  easy_install -U setuptools==30.0.0
-  pip install appdirs==1.4.0
-  pip install virtualenv
-
-Create a virtual environment::
-
-  virtualenv ~/yardstick_venv
-  export YARDSTICK_VENV=~/yardstick_venv
-  source ~/yardstick_venv/bin/activate
-
-Download the source code and install Yardstick from it::
-
-  git clone https://gerrit.opnfv.org/gerrit/yardstick
-  export YARDSTICK_REPO_DIR=~/yardstick
-  cd yardstick
-  ./install.sh
-
-
-After *Yardstick* is installed, executing the "nsb_setup.sh" script to setup
-NSB testing::
-
-  ./nsb_setup.sh
-
-It will also automatically download all the packages needed for NSB Testing setup.

-Enable yardstick virtual environment
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Before executing yardstick test cases, make sure to activate yardstick
-python virtual environment if runnin on ubuntu without docker::
-
-    source /opt/nsb_bin/yardstick_venv/bin/activate
-
-On docker, virtual env is in main path.
-
-Run Yardstick - Network Service Testcases
------------------------------------------
-
-NS testing - using NSBperf CLI
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-::
-
-  PYTHONPATH: ". ~/.bash_profile"
-  cd <yardstick_repo>/yardstick/cmd
-
- Execute command: ./NSPerf.py -h
-      ./NSBperf.py --vnf <selected vnf> --test <rfc test>
-      eg: ./NSBperf.py --vnf vpe --test tc_baremetal_rfc2544_ipv4_1flow_64B.yaml
-
-NS testing - using yardstick CLI
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-::
-  PYTHONPATH: ". ~/.bash_profile"
-
-Go to test case forlder type we want to execute.
-      e.g. <yardstick repo>/samples/vnf_samples/nsut/<vnf>/
-      run: yardstick --debug task start <test_case.yaml>
-
-Network Service Benchmarking - Standalone Virtualization
---------------------------------------------------------
-
-SRIOV:
------
-
-Pre-requisites
-^^^^^^^^^^^^^^
-
-On Host:
- a) Create a bridge for VM to connect to external network
-    brctl addbr br-int
-    brctl addif br-int <interface_name>    #This interface is connected to internet
-
- b) Build guest image for VNF to run.
-    Most of the sample test cases in Yardstick are using a guest image called
-    ``yardstick-image`` which deviates from an Ubuntu Cloud Server image
-    Yardstick has a tool for building this custom image with samplevnf.
-    It is necessary to have ``sudo`` rights to use this tool.
-
-    Also you may need to install several additional packages to use this tool, by
-    follwing the commands below::
-
-       sudo apt-get update && sudo apt-get install -y qemu-utils kpartx
-
-    This image can be built using the following command in the directory where Yardstick is installed::
-
-       export YARD_IMG_ARCH='amd64'
-       sudo echo "Defaults env_keep += \'YARD_IMG_ARCH\'" >> /etc/sudoers
-       sudo tools/yardstick-img-dpdk-modify tools/ubuntu-server-cloudimg-samplevnf-modify.sh
-
-    for more details refer chapter :doc:`04-installation``
-
-Note: VM should be build with static IP and should be accessiable from yardstick host.

-Enable yardstick virtual environment
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Before executing yardstick test cases, make sure to activate yardstick
-python virtual environment if runnin on ubuntu without docker::
-
-    source /opt/nsb_bin/yardstick_venv/bin/activate
-
-On docker, virtual env is in main path.
-
-Run Yardstick - Network Service Testcases
------------------------------------------
-
-NS testing - using NSBperf CLI
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-::
-
-  PYTHONPATH: ". ~/.bash_profile"
-  cd <yardstick_repo>/yardstick/cmd
-
- Execute command: ./NSPerf.py -h
-      ./NSBperf.py --vnf <selected vnf> --test <rfc test>
-      eg: ./NSBperf.py --vnf vfw --test tc_sriov_rfc2544_ipv4_1flow_64B.yaml
-
-NS testing - using yardstick CLI
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-::
-  PYTHONPATH: ". ~/.bash_profile"
-
-Go to test case forlder type we want to execute.
-      e.g. <yardstick repo>/samples/vnf_samples/nsut/<vnf>/
-      run: yardstick --debug task start <test_case.yaml>
-
-OVS-DPDK:
------
-
-Pre-requisites
-^^^^^^^^^^^^^^
-
-On Host:
- a) Create a bridge for VM to connect to external network
-    brctl addbr br-int
-    brctl addif br-int <interface_name>    #This interface is connected to internet
-
- b) Build guest image for VNF to run.
-    Most of the sample test cases in Yardstick are using a guest image called
-    ``yardstick-image`` which deviates from an Ubuntu Cloud Server image
-    Yardstick has a tool for building this custom image with samplevnf.
-    It is necessary to have ``sudo`` rights to use this tool.
-
-    Also you may need to install several additional packages to use this tool, by
-    follwing the commands below::
-
-       sudo apt-get update && sudo apt-get install -y qemu-utils kpartx
-
-    This image can be built using the following command in the directory where Yardstick is installed::
-
-       export YARD_IMG_ARCH='amd64'
-       sudo echo "Defaults env_keep += \'YARD_IMG_ARCH\'" >> /etc/sudoers
-       sudo tools/yardstick-img-dpdk-modify tools/ubuntu-server-cloudimg-samplevnf-modify.sh
-
-    for more details refer chapter :doc:`04-installation``
-
-Note: VM should be build with static IP and should be accessiable from yardstick host.
-
-  c) OVS & DPDK version.
-     - OVS 2.7 and DPDK 16.11.1 above version is supported
-
-  d) Setup OVS/DPDK on host.
-     Please refer below link on how to setup .. _ovs-dpdk: http://docs.openvswitch.org/en/latest/intro/install/dpdk/
