The main Moongen repository now has LUA scripts contributed by Netronome, to better simulate a real world traffic pattern. Enhance VSPERF to permit selection of traffic pattern to be used, and allow this generated pattern as an option.

see: examples/netronome-packetgen in the main Moongen repository

Synopsis extracted from the LUA script is below, that describes the traffic pattern.

Packetgen uses MoonGen to generate a bursty traffic patten at high packet rates.

The traffic pattern has the following properties:

-) All packets generated will share the same source IP, source MAC and size
profile (fixed size of IMIX, see below).
-) The destination IP and MAC are selected sequentially as per the above
pattern.
-) The sets of streams are separated by the MAC and IP stride, and each
stream is repeated in bursts.
-) The destination IP and MAC increase in lock-step.
-) Packets size can be fixed (specified when running), or selected from a
7:4:1 IMIX profile with packet sizes of 1514, 570, or 64, respectively.
