It sounds like you are looking for a network impairment generator. There are
a multitude of commercial appliances out there that will do this. Shunra is
one that I have used in the past. If you are looking for F/OSS running on
Linux, then take a look at NISTNet (  http://snad.ncsl.nist.gov/nistnet/).
It is beta, and has been for a very long time, but it works. I have used it
in various areas of network testing and pro-active troubleshooting.

HTH,
