When testing networking for a customer with high-speed, long-latency
network issues I used a nistnet setup with three computers: One in the
middle w/two network cards (gigabit, in this case), running nistnet,
and two others representing the endpoints. The nistnet software let
me set bandwidth, latency, packet loss etc. In addition I used 'pload'
just for graphical monitoring of speed. This worked very well and you
can really simulate just about anything. (NB: As soon as you go into
high bandwith, long latency setups you'll begin to get affected by the
kernel's networking setup itself, which may affect things.)
