I'm looking for test software that can generate test streams with the TCP/IP protocol, but limit the rate of the test data. For example, if using 100Mbps Ethernet, I would like to be able to generate a 1Mbps TCP/IP stream.

Tools like Iperf/Jperf can test with UDP at a specific rate, but TCP will always attempt to maximize its throughput.

Ideally, the tool would support Windows and IPv6.

nuttcp can limit the speed at which the transmitter sends data to the network. Check the -R option...

It´s part of pS-Performance Toolkit / BWCTL - Bandwidth Test Controller
