+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.
+
+
+Prerequisites
+-------------
+
+Refer chapter Yardstick Installation for more information on yardstick
+prerequisites

+
+  - build-essential
+
+  - automake
+
+  - libtool

+Install Yardstick (NSB Testing)
+-------------------------------
+
+Download the source code and install Yardstick from it
+
+.. code-block:: console
+
+  git clone https://gerrit.opnfv.org/gerrit/yardstick
+
+  cd yardstick
+
+  # Switch to latest stable branch
+  # git checkout <tag or stable branch>
+  git checkout stable/euphrates
+
+  # For Bare-Metal or Standalone Virtualization
+  ./nsb_setup.sh
+
+  # For OpenStack
+  ./nsb_setup.sh <path to admin-openrc.sh>
+
+
+Above command setup docker with latest yardstick code. To execute
+
+.. code-block:: console
+
+  docker exec -it yardstick bash
+
+It will also automatically download all the packages needed for NSB Testing setup.
+Refer chapter :doc:`04-installation` for more on docker **Install Yardstick using Docker (recommended)**

+
+On 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.
+    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.

+OVS-DPDK Pre-requisites
+#######################
+
+On 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.
+    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::
+
+       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 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.
+     Please refer to below link on how to setup `OVS-DPDK <http://docs.openvswitch.org/en/latest/intro/install/dpdk/>`_

+--------------------------------
+
+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.
+
+2. Update pod_ixia.yaml file with ixia details.

+
+  for sriov/ovs_dpdk pod files, please refer to above Standalone Virtualization for ovs-dpdk/sriov configuration
+
+3. Start IxOS TCL Server (Install 'Ixia IxExplorer IxOS <version>')
+   You will also need to configure the IxLoad machine to start the IXIA
+   IxosTclServer. This can be started like so:
+
+   - Connect to the IxLoad machine using RDP
+   - Go to:
+    ``Start->Programs->Ixia->IxOS->IxOS 8.01-GA-Patch1->Ixia Tcl Server IxOS 8.01-GA-Patch1``
+     or
+    ``"C:\Program Files (x86)\Ixia\IxOS\8.01-GA-Patch1\ixTclServer.exe"``
+
+4. Create a folder "Results" in c:\ and share the folder on the network.
+
+5. execute testcase in samplevnf folder.

+
+1. Software needed: ``IxNetworkAPI<ixnetwork verson>Linux64.bin.tgz`` (Download from ixia support site)
+                     Install - ``IxNetworkAPI<ixnetwork verson>Linux64.bin.tgz``
+2. Update pod_ixia.yaml file with ixia details.
+
+  .. code-block:: console

+
+3. Start IxNetwork TCL Server
+   You will also need to configure the IxNetwork machine to start the IXIA
+   IxNetworkTclServer. This can be started like so:
+
+    - Connect to the IxNetwork machine using RDP
+    - Go to:     ``Start->Programs->Ixia->IxNetwork->IxNetwork 7.21.893.14 GA->IxNetworkTclServer`` (or ``IxNetworkApiServer``)
+
+4. execute testcase in samplevnf folder.
+   eg ``<repo>/samples/vnf_samples/nsut/vfw/tc_baremetal_rfc2544_ipv4_1rule_1flow_64B_ixia.yaml``
