SUTs run Testpmd SW application in Linux user-mode as a +Device Under Test (DUT). TG runs TRex SW application as a packet Traffic +Generator. Physical connectivity between SUTs and to TG is provided using +different NIC models that need to be tested for performance. Currently +installed and tested NIC models include: + +#. 2port10GE X520-DA2 Intel. +#. 2port10GE X710 Intel. +#. 2port10GE VIC1227 Cisco. +#. 2port40GE VIC1385 Cisco. +#. 2port40GE XL710 Intel. + +Detailed LF FD.io test bed specification and topology is described on `CSIT LF +testbed wiki page <https://wiki.fd.io/view/CSIT/CSIT_LF_testbed>`_. + +Testpmd Performance Tests Overview +---------------------------------- + +Performance tests are split into two main categories: + +- Throughput discovery - discovery of packet forwarding rate using binary search + in accordance to RFC2544. + + - NDR - discovery of Non Drop Rate, zero packet loss. + - PDR - discovery of Partial Drop Rate, with specified non-zero packet loss. + +- Throughput verification - verification of packet forwarding rate against + previously discovered throughput rate. These tests are currently done against + 0.9 of reference NDR, with reference rates updated periodically. + +CSIT |release| includes following performance test suites: + +- 2port10GE X520-DA2 Intel + + - **L2XC** - L2 Cross-Connect forwarding of untagged Ethernet frames. |
