`TRex traffic generator <https://wiki.fd.io/view/TRex>`_ is used for all
CSIT performance tests. TRex stateless mode is used to measure NDR and
-PDR throughputs using binary search (NDR and PDR discovery tests) and
-for quick checks of DUT performance against the reference NDRs (NDR
-check tests) for specific configuration.
+PDR throughputs using MLRsearch and to measure maximum transer rate
+in MRR tests.
TRex is installed and run on the TG compute node. The typical procedure
is:
- TRex is started in the background mode
::
- $ sh -c 'cd <t-rex-install-dir>/scripts/ && sudo nohup ./t-rex-64 -i -c 7 --iom 0 > /tmp/trex.log 2>&1 &' > /dev/null
+ $ sh -c 'cd <t-rex-install-dir>/scripts/ && sudo nohup ./t-rex-64 -i -c 7 > /tmp/trex.log 2>&1 &' > /dev/null
- There are traffic streams dynamically prepared for each test, based on traffic
profiles. The traffic is sent and the statistics obtained using
- :command:`trex_stl_lib.api.STLClient`.
+ :command:`trex.stl.api.STLClient`.
