You can also look at <http://www.linuxfoundation.org/en/Net:Netem>.
I use Netem to simulate satellite delay. My configured delays are
about 265 ms each way with 2 ms of variation. Works really well and
support is compiled directly recent Ubuntu Linux versions and probably
many others as well. I used a single box with 802.1q support on it
and a couple of VLANs configured in bridging mode so the Linux box is
just transparent to the devices under test. Use a VLAN trunking
capable switch to break out the VLANs to as many devices as you need.

Subject: [c-nsp] TCP throughput /WAN delay simulation with
back to back routers
Hello Folks ,
I am trying to test TCP throughput with different variables.
I want to simulate a delay of aprox 45msec between two test
PCs connected two bat to back routers . How do we introduce
an artificial delay where in the actual delay is on 2-3
msec.Using cisco routers.?
Thilak
