 The traffic generation component is in charge of contrilling the TRex traffic generator using its python API.
 It includes tasks such as:

 NFVbench is a python application that is designed to run in a compact and portable format inside a container and on production pods.
 As such it only uses open sourec software with minimal hardware requirements (just a NIC card that is DPDK compatible).
 Traffic generation is handled by TRex on 2 physical ports (2x10G or higher) forming traffic loops up to VNF level and following
