4 This section includes summary graphs of VPP Phy-to-Phy packet latency
5 with IPv4 Routed-Forwarding measured at 50% of discovered NDR throughput
6 rate. Latency is reported for VPP running in multiple configurations of
7 VPP worker thread(s), a.k.a. VPP data plane thread(s), and their
8 physical CPU core(s) placement.
10 Results are generated from a single execution of CSIT NDR discovery
11 test. Box plots are used to show the Minimum, Average and Maximum packet
14 *Title of each graph* is a regex (regular expression) matching all
15 throughput test cases plotted on this graph, *X-axis labels* are indices
16 of individual test suites executed by csit-vpp-perf-1704-all job that
17 created result output file used as data source for the graph, *Y-axis
18 labels* are measured packet Latency [uSec] values, and the *Graph
19 legend* lists the plotted test suites and their indices. Latency is
20 reported for concurrent symmetric bi-directional flows, separately for
21 each direction: i) West-to-East: TGint1-to-SUT1-to-SUT2-to-TGint2, and
22 ii) East-to-West: TGint2-to-SUT2-to-SUT1-to-TGint1.
