VNF Service Chains
==================

.. important::

    **DISCLAIMER**: Presented test results should be taken with a pinch of
    salt as they may not represent correctly the system behaviour due
    to experimental nature of used test methodology (see :ref:`reconf_tests`).

In each test, a single service chain is added, the re-configuration
contains all the steps the initial chains got, except the last step
(starting VMs) is skipped.

Additional information about graph data:

#. **Graph Title**: describes tested VPP packet path. Format:

   - wire encapsulation ``dot1qip4vlxan``,
   - VPP forwarding mode ``l2bd``,
   - total number {Y} of service chains ``{Y}ch``,
   - total number of chains being reconfigured ``1ach``,
   - total number of vhost-user interfaces forwarding packets on VPP with {Y}
     chains and {X} VMs per chain ``{2XY}vh`` (2 interfaces per {X} VMs per {Y}
     chains),
   - total number {XY} of VNF VMs forwarding packets ``{XY}vm`` and finally
   - VNF workload in VM ``testpmd``.

#. **X-axis Labels**: indices of individual test suites as listed in
   Graph Legend.

#. **Y-axis Labels**: measured Implied time loss [s] values.

#. **Graph Legend**: lists X-axis indices with associated CSIT test
   suites executed to generate graphed test results and the average value and
   standard deviation of measured packet loss in millions of packets.

#. **Hover Information**: lists minimum, first quartile, median,
   third quartile, and maximum. If either type of outlier is present the
   whisker on the appropriate side is taken to 1.5×IQR from the quartile
   (the "inner fence") rather than the max or min, and individual outlying
   data points are displayed as unfilled circles (for suspected outliers)
   or filled circles (for outliers). (The "outer fence" is 3×IQR from the
   quartile.)

.. note::

    Test results have been generated by
    `FD.io test executor vpp performance job 2n-skx`_ with RF
    result files csit-vpp-perf-|srelease|-\*.zip
    `archived here <../../_static/archive/>`_.
