IPv4 Overlay Tunnels
====================

Following sections include summary graphs of VPP Phy-to-Phy performance
with IPv4 Overlay Tunnels, 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.

NDR Throughput
~~~~~~~~~~~~~~

VPP NDR 64B packet throughput in 1t1c setup (1thread, 1core) is presented
in the graph below.

PDR Throughput
~~~~~~~~~~~~~~

VPP PDR 64B packet throughput in 1t1c setup (1thread, 1core) is presented
in the graph below. PDR measured for 0.5% packet loss ratio.
