I think your best bet is to run NPD.

Huh? That looks at routing [in]stability, not goodput. Is this an intentional red herring?

While the routing study I presented at the Feb NANOG was based on measurements made using NPD, the daemon can also be used for taking TCP data. I'm right now analyzing a bunch of such and hope to have some results to present at the early '97 NANOG. That said, NPD (1) does *not* provide any *analysis* itself, just measurement, and (2) is far from industrial strength. So it's not something that someone can use right now for doing any sort of standardized measurement. Matt Mathis, Jamshid Mahdavi (both of PSC) & I are hoping to get funded to build an industrial strength version of NPD, along with the key pieces of the infrastructure for using it on a widespread basis, and analysis tools for automating measurements. If this comes through, then with luck we'll have something to present about it at the '97 NANOG, too. Vern
