flow generating tool

[jiaruchen at gmail.com (jiaruchen at gmail.com)]

Iperf(linux) and jperf(windows) does generate traffic flows. You simply set up sender/receiver and it'll generate traffic load. It can generate 10gig line rate unicast flows but multicast replication is limited because it is software based. 

Iperf/jperf however, is not as flexible or anywhere as feature rich and powerful as some of the other hardware solutions as mentioned earlier - ex: ixia, spirent etc.

Perhaps not a tool as in software, but clearly something that you might want
to have a look at : 

Ixia and Spirent devices ... Those are mostly used for applications like
generating different kind of traffic.
