+# General Coding Style
+
+## Code
+
+Abide by [PEP-8] for general code. Some particular points to note:
+
+* Wrap code at 79 characters.
+* Use only spaces - no tabs.
+* Use implicit string concatenation where possible. Don't use the escape
+  character unless absolutely necessary.
+* Be liberal in your use of whitespace to group related statements together.
+  However, don't leave a space after the docstring and the first statement.
+* Use single quotes for all string literals.
+
+## Documentation
+
+Follow [PEP-257] and the [Sphinx guidelines] for documentation. In particular:
+
+* Wrap docstrings at 72 characters.
+* Use double-quotes for all docstrings.
+* Write all inline comments in lower-case, except where using a name/initialism.
+* Document **all** library functions/classes completely. Tests, however, only need a test case docstring.
+
+To summarise the docstring conventions:
+
+```python
+def my_function(athing, stuff=5):
+   """
+   Summary line here in imperative tense.
+
+   Longer description here...
+
+   :param athing: Details about this paramter here
+   :param stuff: Ditto
+
+   :returns: None
+   """
+   pass  # code here...
+```
+
+### Validation
+
+All code should be checked with the PyLint linter and PEP8 style guide checker.
+Pylint can be run like so:
+
+```bash
+pylint <file or directory>
+```
+
+Most PyLint errors should be resolved. You will need to do this manually.
+However, there are cases where they may not make sense (e.g. you **need** to
+pass `N` parameters to a function). In this case, disable the relevant
+case using an inline `disable` like so:
+
+```python
+# pylint: disable=[code]
+```
+
+On the other hand, all PEP8 errors should be resolved.

+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+#May 2015
+
+This is the initial release of a re-designed version of the software based on
+community feedback.  This initial release supports only the Phy2Phy deployment
+scenario and the LTD.Throughput.RFC2544.PacketLossRatio test - both described
+in the OPNFV vswitchperf 'CHARACTERIZE VSWITCH PERFORMANCE FOR TELCO NFV USE
+CASES LEVEL TEST DESIGN'.  The intention is that more test cases will follow
+once the community has digested the initial release.
+
+## New
+
+* CentOS7 support
+  * Verified on CentOS7
+  * Install & Quickstart documentation
+
+* Better support for mixing tests types with Deployment Scenarios
+* Re-work based on community feedback of TOIT
+  * Framework support for other vSwitches
+  * Framework support for non-Ixia traffic generators
+  * Framework support for different VNFs
+* Python3
+
+## Missing
+
+* Report generation is currently disabled
+* xmlunit output is  currently disabled
+* VNF support.

+# Installing toit
+
+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 (see https://www.softwarecollections.org/en/scls/rhscl/python33)
+should be enabled.
+
+Install the requirements as specified below.
+
+---
+## Enable Software Collections (SCL)
+
+```bash
+yum -y install scl-utils
+yum -y install https://www.softwarecollections.org/en/scls/rhscl/python33/epel-7-x86_64/download/rhscl-python33-epel-7-x86_64.noarch.rpm
+```
+
+## System packages
+
+There are a number of packages that must be installed using `yum`. These can be installed like so:
+
+```bash
+yum -y --exclude=python33-mod_wsgi* install python33-* pciutils
+```
+
+---
+
+## Python 3 Packages
+
+To avoid file permission errors and Python version issues, use virtualenv to create an isolated environment with Python3.
+The required Python 3 packages can be found in the `requirements.txt` file in the root of the test suite.
+They can be installed in your virtual environment like so:
+
+```bash
+scl enable python33 bash
+# Create virtual environment
+virtualenv vsperfenv
+cd vsperfenv
+source bin/activate
+pip install -r requirements.txt
+```
+
+You need to activate the virtual environment everytime you start a new shell session.
+To activate, simple run:
+
+```bash
+scl enable python33 bash
+cd 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:
+
+```bash
+export http_proxy=proxy.mycompany.com:123
+export https_proxy=proxy.mycompany.com:123
+```

+# Getting Started with 'vsperf'
+
+## Installation
+
+Follow the [installation instructions] to install.
+
+---
+
+## Configure the `./conf/10_custom.conf` file
+
+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
+
+Alternatively a custom settings file can be passed to `vsperf` via the
+`--conf-file` argument.
+
+```bash
+./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
+
+To list the available tests:
+
+```bash
+./vsperf --list-tests
+```
+
+To run a group of tests, for example all tests with a name containing
+'RFC2544':
+
+```bash
+./vsperf --conf-file=user_settings.py --tests="RFC2544"
+```
+
+To run all tests:
+
+```bash
+./vsperf --conf-file=user_settings.py
+```
+
+Some tests allow for configurable parameters, including test duration (in
+seconds) as well as packet sizes (in bytes).
+
+```bash
+./vsperf --conf-file user_settings.py
+    --tests RFC2544Tput
+    --test-param "rfc2544_duration=10;packet_sizes=128"
+```
+
+For all available options, check out the help dialog:
+
+```bash
+./vsperf --help
+```

+"""IxNetwork traffic generator model.
+
+Provides a model for an IxNetwork machine and appropriate applications.
+
+This requires the following settings in your config file:
+
+* TRAFFICGEN_IXNET_LIB_PATH
+    IxNetwork libraries path
+* TRAFFICGEN_IXNET_HOST
+    IxNetwork host IP address
+* TRAFFICGEN_IXNET_PORT
+    IxNetwork host port number
+* TRAFFICGEN_IXNET_USER
+    IxNetwork host user name
+* TRAFFICGEN_IXNET_TESTER_RESULT_DIR
+    The result directory on the IxNetwork computer
+* TRAFFICGEN_IXNET_DUT_RESULT_DIR
+    The result directory on DUT. This needs to map to the same directory
+    as the previous one
+
+The following settings are also required. These can likely be shared
+an 'Ixia' traffic generator instance:
+
+* TRAFFICGEN_IXIA_HOST
+    IXIA chassis IP address
+* TRAFFICGEN_IXIA_CARD
+    IXIA card
+* TRAFFICGEN_IXIA_PORT1
+    IXIA Tx port
+* TRAFFICGEN_IXIA_PORT2
+    IXIA Rx port
+
+If any of these don't exist, the application will raise an exception
+(EAFP).
+
+Additional Configuration:
+-------------------------
+
+You will also need to configure the IxNetwork machine to start the IXIA
+IxNetworkTclServer. This can be started like so:
+
+1. Connect to the IxNetwork machine using RDP
+2. Go to:
+
+    Start->
+      Programs ->
+        Ixia ->
+          IxNetwork ->
+            IxNetwork 7.21.893.14 GA ->
+              IxNetworkTclServer
+
+   Pin a shortcut to this application to the taskbar.
+3. Before running it right click the pinned shortcut  and go to
+   "Properties". Here change the port number to your own port number.
+   This will be the same value as "TRAFFICGEN_IXNET_PORT" above.
+4. You will find this on the shortcut tab under the heading "Target"
+5. Finally run it. If you see the following error check that you
+   followed the above steps exactly:
+
+       ERROR: couldn't open socket : connection refused
+
+Debugging:
+----------
+
+This method of automation is quite error prone as the IxNetwork API
+does not give any feedback as to the status of tests. As such, it can
+be expected that the user have access to the IxNetwork machine should
+this trafficgen need to be debugged.
