IPv4 Routed-Forwarding
======================

Following sections include summary graphs of VPP Phy-to-Phy performance
with IPv4 Routed-Forwarding, including NDR throughput (zero packet loss)
and PDR throughput (<0.5% packet loss). Performance is reported for VPP
running in multiple configurations of VPP worker thread(s), a.k.a. VPP
data plane thread(s), and their physical CPU core(s) placement.

Results are generated by multiple executions of the same CSIT tests.
In order to display variation in measured throughput values, Box-and-
whisker plots are used to show their quartiles (Min, 1st quartile / 25th
percentile, 2nd quartile / 50th percentile / mean, 3rd quartile / 75th
percentile, Max). Outliers are plotted as individual points.

*Title of each graph* is a regex (regular expression) matching all
throughput test cases plotted on this graph, *X-axis labels* are indices
of individual test suites executed by csit-vpp-perf-1704-all jobs that
created result output files used as data sources for the graph, *Y-axis
labels* are measured Packets Per Second [pps] values, and the *Graph
legend* lists the plotted test suites and their indices.

.. note::

    Test results have been generated by FD.io test executor jobs
    `csit-vpp-perf-1704-all
    <https://jenkins.fd.io/view/csit/job/csit-vpp-perf-1704-all/>`_,
