+NAT44 IPv4 Routing
+==================
+
+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.
+
+CSIT source code for the test cases used for plots can be found in
+`CSIT git repository <https://git.fd.io/csit/tree/tests/vpp/perf/ip4?h=rls2001>`_.
