I did the same. I used ttcp and recorded the bandwidth I could use. But my
results where nearly perfetc (I recorder the bandwidth on a very log period).
Recently I tried it with upd data but I had some strange results. 1 UDP data
stream was shaped perfectly, but 2 UPD data streams can use the full link
bandwidth. I still have to test ir further.
