Packet Latency
==============
-Plotted results are generated from a single execution of CSIT NDR discovery
-test. Box plots are used to show the Minimum, Median and Maximum packet
+Latency results are generated from a single execution of NDR discovery
+test across physical testbeds hosted LF FD.io labs: 3n-hsw, 2n-skx, 2n-
+skx. Box plots are used to show the Minimum, Median and Maximum packet
latency per test.
-*Title of each graph* describes the packet path, testbed topology, processor
-architecture, packet size, number of cores and threads used by workers and
-DUT configuration, *X-axis labels* are indices of individual test suites
-executed by FD.io test executor vpp performance jobs that created result output
-file used as data source for the graph, *Y-axis labels* are measured packet
-Latency [uSec] values, and the *Graph legend* lists the plotted test suites and
-their indices. Latency is reported for concurrent symmetric bi-directional
-flows, separately for each direction: i) West-to-East:
-TGint1-to-SUT1-to-SUT2-to-TGint2, and ii) East-to-West:
-TGint2-to-SUT2-to-SUT1-to-TGint1.
+Additional information about graph data:
+
+#. **Graph Title**: describes tested packet path, testbed topology,
+ processor model, NIC model, packet size, number of cores and
+ threads used by data plane workers and indication of DUT
+ configuration.
+
+#. **X-axis Labels**: indices of individual test suites as listed in
+ Graph Legend and direction of latency flow:
+
+ - West-to-East: TGint1-to-SUT1-to-SUT2-to-TGint2.
+ - East-to-West: TGint2-to-SUT2-to-SUT1-to-TGint1.
+
+#. **Y-axis Labels**: measured packet latency values in [uSec].
+
+#. **Graph Legend**: lists X-axis indices with associated CSIT test
+ suites executed to generate graphed test results.
+
+#. **Hover Information**: lists number of runs executed, specific test
+ substring, packet flow direction, maximal, mean and minimal values of
+ measured latencies.
.. note::
Test results have been generated by
`FD.io test executor vpp performance job 3n-hsw`_,
`FD.io test executor vpp performance job 3n-skx`_ and
- `FD.io test executor vpp performance job 2n-skx`_ with Robot Framework
+ `FD.io test executor vpp performance job 2n-skx`_ with RF
result files csit-vpp-perf-|srelease|-\*.zip
`archived here <../../_static/archive/>`_.
- Plotted data set size per test case is equal to the number of job executions
- presented in this report version: **10**.
