Nitpick... I think you mean "introduce artificial" or "emulate" rather
than "simulate". For network simulation you could use something like
the NS2 Network Simulator, which I'm sure has arbitrarily configurable
delays/losses etc. per link.

Most people seem to use Dummynet for FreeBSD:
http://info.iet.unipi.it/~luigi/ip_dummynet/
For Linux, there's NIST NET:
http://cs.ecs.baylor.edu/~donahoo/tools/nistnet/
For Solaris, there's ONE (Ohio Network Emulator):
http://masaka.cs.ohiou.edu/one/
Note that I don't have personal experience with any of these, but I
know that at least Dummynet and NIST NET have succefully been used for
research...
