[TRex traffic generator](https://trex-tgn.cisco.com) is used for majority of
CSIT performance tests. TRex is used in multiple types of performance tests,

## Traffic modes
If measurement of latency is requested, two more packet streams are
created (one for each direction) with TRex flow_stats parameter set to
STLFlowLatencyStats. In that case, returned statistics will also include
-min/avg/max latency values and encoded HDRHistogram data.
