Packet LatencyΒΆ

Latency results are generated from a single execution of NDR discovery test across physical testbeds hosted LF FD.io labs: 3n-hsw, 2n-skx, 2n- skx. Box plots are used to show the Minimum, Median and Maximum packet latency per test.

Additional information about graph data:

  1. Graph Title: describes tested packet path, testbed topology, processor model, NIC model, packet size, number of cores and threads used by data plane workers and indication of DUT configuration.
  2. X-axis Labels: indices of individual test suites as listed in Graph Legend and direction of latency flow:
    • West-to-East: TGint1-to-SUT1-to-SUT2-to-TGint2.
    • East-to-West: TGint2-to-SUT2-to-SUT1-to-TGint1.
  3. Y-axis Labels: measured packet latency values in [uSec].
  4. Graph Legend: lists X-axis indices with associated CSIT test suites executed to generate graphed test results.

Note

Test results have been generated by FD.io test executor dpdk performance job 3n-hsw, FD.io test executor dpdk performance job 3n-skx and FD.io test executor dpdk performance job 2n-skx with RF result files csit-dpdk-perf-1807-*.zip archived here.
