2.3.4. 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.

2.3.4.1. NDR Throughput

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

2.3.4.2. 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.
