Data Plane ThroughputΒΆ

Network data plane packet and bandwidth throughput are measured in accordance with RFC 2544, using FD.io CSIT Multiple Loss Ratio search (MLRsearch), an optimized throughput search algorithm, that measures SUT/DUT packet throughput rates at different Packet Loss Ratio (PLR) values.

Following MLRsearch values are measured across a range of L2 frame sizes and reported:

  • NON DROP RATE (NDR): packet and bandwidth throughput at PLR=0%.
    • Aggregate packet rate: NDR_LOWER <bi-directional packet rate> pps.
    • Aggregate bandwidth rate: NDR_LOWER <bi-directional bandwidth rate> Gbps.
  • PARTIAL DROP RATE (PDR): packet and bandwidth throughput at PLR=0.5%.
    • Aggregate packet rate: PDR_LOWER <bi-directional packet rate> pps.
    • Aggregate bandwidth rate: PDR_LOWER <bi-directional bandwidth rate> Gbps.

NDR and PDR are measured for the following L2 frame sizes (untagged Ethernet):

  • IPv4 payload: 64B, IMIX (28x64B, 16x570B, 4x1518B), 1518B, 9000B.
  • IPv6 payload: 78B, IMIX (28x78B, 16x570B, 4x1518B), 1518B, 9000B.

All rates are reported from external Traffic Generator perspective.
