dummynet(4)? It's a standard part of FreeBSD and may be in other BSDs.
It's very configurable to generate delays, congestion like behavior
and such.
NAME
dummynet - traffic shaper, bandwidth manager and delay emulator
DESCRIPTION
dummynet is a system facility that permits the control of traffic going
through the various network interfaces, by applying bandwidth and queue
size limitations, implementing different scheduling and queue management
policies, and emulating delays and losses.
