2.3.5. IPv6 Overlay Tunnels

Following sections provide a summary of VPP Phy-to-Phy IPv6 Overlay Tunnels performance illustrating 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.

Title of each graph is a regex (regular expression) matching all plotted throughput test cases, X-axis labels are indeces of csit-vpp-perf-1701 jobs that created result output files used as data sources for the graph, Y-axis labels are measured Packets Per Second [pps] values, and the graph legend identifes the plotted test suites.

Note

Data sources for reported test results: i) FD.io test executor jobs csit-vpp-perf-1701-all and csit-vpp-perf-1701-long , ii) archived FD.io jobs test result output files.

2.3.5.1. NDR Throughput

VPP NDR Throughput - running in configuration of one worker thread (1t) on one physical core (1c) - is presented in the figure below.
