  I would think you might be interested in looking at our
work on the Congestion Manager from a few years ago:


  You might find it relevant.  Not only do we have an ns-2
evaluation, but we've implemented it in Linux;  the source code is
freely available.  If your algorithms are substantial improvements
over those we used, the CM may provide the kind of nice, modular
framework you would want in which to actually implement your own
