Hello,

I'm trying to figure out if it is possible to get iPerf to simulate
certain transmission patterns. In particular, I'd like to send a mix
of packet sizes in one session so I can measure it's affect on jitter
in another session.

I'd also like to be able to send a stream that is designed to emulate
VOIP, so I can assess how well the network (with the congestion
stream mentioned above in play) will support the VOIP stream.

Can iPerf do either of these things? If not, can anyone recommend any
freely available Unix tools that can?

Thanks,
Avram

Are you wanting to saturate the network or just provide a pattern of traffic?

I've written similar sort of code for video conferencing which
consists of creating audio and video layers. If you're interested send
me an email off-list.
