We have a network product that runs on Linux and needs to be tested in reduced bandwidth networks. We have been able to use 'tc' (traffic control) in Linux and dummynet in FreeBSD to inject delay (latency) with predictable behavior. But when we try to throttle the bandwidth with either of these, it does not seem to have much effect. Here is an example of trying to use 'tc' to set the bandwidth to 512Kbps: tc qdisc change dev eth0 root tbf rate 512kbit burst 1540 But when we run 'scp' over that connection we see speeds that are way higher than we expect. Here are results of setting various bandwidths in both dummynet and tc. You can see that it has SOME effect but not very much.
