L2 Ethernet Switching ===================== Following sections include summary graphs of VPP Phy-to-Phy performance with L2 Ethernet switching, 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. .. raw:: html *Figure 1a.
