Any non-small collection of Windows machines will do this all by themselves. :-) Joke aside, you could use IPerf in UDP mode between to hosts: server$ iperf -s -u -p 4999 client$ iperf -c <server_ip> -u -b 1000M -p 4999 If you just want to stress a link a don't care about measuring loss etc. you could use "nc" in UDP mode sourcing from /dev/zero: client$ dd if=/dev/zero count=666666 bs=1500 | nc -u <server_ip> You might face some problems trying to make PC hardware deliver multi gigabit loads, but several PCs in parallel can do it.
