I interpret the question to mean networks where is there significant
actual delay along them.  I seem to recall that there are some ways to
do this Linux machines, but most commercial test equipment can simulate
things, including dropping packets.
I think, however, that we do not want/need and packets dropped, as then
the bandwidth constraint would not be in the device under test.
