Functest has become the repo hosting proposed traffic profiles for OPNFV. The current traffic profiles are very generally specified, giving fractions of total traffic on different directions of transmission.
The LTD needs to include the possibility of IMIX testing, but reference the repo for a living list of traffic profiles. There should also be some cautions that small modifications to IMIX packet sizes or proportions of total can have a profound affect on the results (which are usually bounded by the extremes of Fixed Packet size testing).
TOIT/VSPERF needs a new feature to specify IMIX packet sizes and frequency, but that is covered by a different VSPERF issue (97).
