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
