+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/>`_.
