If you haven't already, please have a look at this page
http://www.icir.org/floyd/red.html

and in particular:
http://www.icir.org/floyd/red.html#ns

The technical report posted there was performed with ns-1, but the tests 
were later ported to ns-2, and I just gave it a try and was able to 
reproduce the plots from Figures 1-5 (with only small differences in the 
output) by running the same commands documented in the report on ns-2.
