Scapy is for functional testing, TRex and `Ixia IxExplorer` are for performance testing. The mechanism in DTS that mananges traffic generators for performance is called `Pktgen`. + +`Ixia IxExplorer` is the principal means used to program Ixia hardware and to perform testing on network devices. Ixia is a hardware traffic generator product of `keysight `_ company.

It generates L3-7 traffic and provides in one tool capabilities. DTS requires to install `Trex` and configure it before lunching DTS.
