+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.
+
+
+Prerequisites
+-------------

+Installing Yardstick on Ubuntu 14.04
+------------------------------------
+
+.. _install-framework:
+
+You can install Yardstick framework directly on Ubuntu 14.04 or in an Ubuntu
+14.04 Docker image. No matter which way you choose to install Yardstick
+framework, the following installation steps are identical.
+
+If you choose to use the Ubuntu 14.04 Docker image, You can pull the Ubuntu
+14.04 Docker image from Docker hub:
+
+::
+
+  docker pull ubuntu:14.04
+
+Installing Yardstick framework
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Download source code and install Yardstick framework:
+
+::
+
+  git clone https://gerrit.opnfv.org/gerrit/yardstick
+  cd yardstick
+  ./nsb_setup.sh
+
+It will also automatically download all the packages needed for NSB Testing setup.
+

+------------------------------------
+
+Environment variables
+^^^^^^^^^^^^^^^^^^^^^
+
+Before running Yardstick (NSB Testing) it is necessary to export traffic
+generator libraries.
+
+::
+
+    source ~/.bash_profile
+
+Config yardstick conf
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+::
+
+    cp ./etc/yardstick/yardstick.conf.sample /etc/yardstick/yardstick.conf
+    vi /etc/yardstick/yardstick.conf
+
+Add trex_path and bin_path in 'nsb' section.
+
+::
+
+  [DEFAULT]
+  debug = True
+  dispatcher = influxdb
+
+  [dispatcher_influxdb]
+  timeout = 5
+  target = http://{YOUR_IP_HERE}:8086
+  db_name = yardstick
+  username = root
+  password = root
+
+  [nsb]
+  trex_path=/opt/nsb_bin/trex/scripts
+  bin_path=/opt/nsb_bin

+
+Config pod.yaml describing Topology
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Before executing Yardstick test cases, make sure that pod.yaml reflects the
+topology and update all the required fields.
+
+::
+
+    cp /etc/yardstick/nodes/pod.yaml.nsb.sample /etc/yardstick/nodes/pod.yaml
+
+Config pod.yaml
+::

+Enable yardstick virtual environment
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Before executing yardstick test cases, make sure to activate yardstick
+python virtual environment
+
+::
+    source /opt/nsb_bin/yardstick_venv/bin/activate
+
+
+Examples and verifying the install
+----------------------------------
+
+It is recommended to verify that Yardstick was installed successfully
+by executing some simple commands and test samples. Before executing yardstick
+test cases make sure yardstick flavor and building yardstick-trusty-server
+image can be found in glance and openrc file is sourced. Below is an example
+invocation of yardstick help command and ping.py test sample:
+::
+
+  yardstick -h
+  yardstick task start samples/ping.yaml
+
+Each testing tool supported by Yardstick has a sample configuration file.
+These configuration files can be found in the **samples** directory.
+
+Default location for the output is ``/tmp/yardstick.out``.
+
+
+Run Yardstick - Network Service Testcases
+-----------------------------------------
+
+NS testing - using NSBperf CLI
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+::
+
+  source /opt/nsb_setup/yardstick_venv/bin/activate
+  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
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+::
+
+  source /opt/nsb_setup/yardstick_venv/bin/activate
+  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>
