Re: Lab Traffic Generator ?

Thanks to all.
Ostinato seems nice, but looks much like iperf/jperf.
It's in the middle of a quick ping and an elaborate pagent load
description (although it seems to support quite a bit of load
management).

To summarize, there seems to be many tools, some quick, some involved.
Some are more load control oriented, some are more content control
oriented. Some also include performance analysis.

In order of complexity:

ping
tfgen/mcaster

jperf/iperf
ostinato

pagent
d-itg

And others for sure.
I did find why tfgen was blowing... it is doing a nasty rewrite of the
code to control the tx, which is not a friendly behaviour nowadays.
Disabling DEP (Data Execution Prevention) brings it back to life.
(security guys, please be quiet)
If you have not seen tfgen, you might like it.
As I said: dest_ip:port, Bw, shoot!
