IPv4 Routed-Forwarding ====================== Following sections include summary graphs ofL3FWD Phy-to-Phy performance with packet routed forwarding, including NDR throughput (zero packet loss) and PDR throughput (<0.5% packet loss). Performance is reported for L3FWD running in multiple configurations of L3FWD pmd thread(s), a.k.a. L3FWD data plane thread(s), and their physical CPU core(s) placement. NDR Throughput ~~~~~~~~~~~~~~ Testpmd NDR 64B packet throughput in 1t1c setup (1thread, 1core) is presented in the graph below. .. raw:: html .. raw:: latex \begin{figure}[H] \centering \graphicspath{{../_build/_static/dpdk/}} \includegraphics[clip, trim=0cm 8cm 5cm 0cm, width=0.70\textwidth]{64B-1t1c-ipv4-ndrdisc} \label{fig:64B-1t1c-ipv4-ndrdisc-dpdk} \end{figure} *Figure 1.
