+IPv4 Tunnels
+============
+
+This section includes summary graphs of VPP Phy-to-Phy packet latency with
+IPv4 Overlay Tunnels measured at 100% of discovered NDR throughput rate.
+Latency 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_tunnels?h=rls2001>`_.
