I suspect that a fair amount of this will be dependent on quite a bit
that was not stated. :-)
That said, this is one of the main purposes behind the Luigi Rizzo's
development of "dummynet" for FreeBSD; from "man dummynet":
HISTORY
dummynet was initially implemented as a testing tool for TCP congestion
control by Luigi Rizzo <luigi at iet.unipi.it>, as described on ACM Computer
Communication Review, Jan.97 issue. Later it has been then modified to
work at the ip and bridging level, integrated with the IPFW packet fil-
ter, and extended to support multiple queueing and scheduling policies.
