2.4.8. Container Orchestrated Topologies

This section includes summary graphs of VPP Phy-to-Phy packet latency with CContainer Orchestrated Topologies measured at 50% 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.

VPP packet latency in 1t1c setup (1thread, 1core) is presented in the graph below.
