That is not really accurate? Linux traffic control (tc, [0]) exists since Kernel 2.2. It can introduce traffic latency and a few other network conditions, like packet loss.

Hmm kind of... I was referring to the fact that dummynet models pipes with a fixed bandwidth and centralized scheduler. Packets are released according to very high precision transmission timing. This means that serialization delay, queue buildup, and link behavior are simulated in a way that resembles real network conditions. Dummynet can provide a highly deterministic timing and queue behavior, which made it popular in networking research and WAN emulation experiments. TC cannot do that with the same accuracy.
I think much like other tools, think SELinux vs OpenBSD (unveil, etc) TC is more flexible (does more things) but there are _some things_ that can't do, and even for things both can do *BSD solutions are much simpler.
