I don't expect your dataset to have flow-level data, and I don't think he did either.
How else do you get a representative measurement of “actual traffic flows on the Internet?” We’ve got adjacency information. Telegeography has hand-waving 40,000 ft. flow estimates in the form of different widths of arrows on a map. But if you want to know how large actual flows of data are between two regions of the Internet, and you can’t actually instrument the whole Internet, you need two things: (1) a broad and representative sampling of flow data, and (2) a complete measurement of a few portions of the network that are represented in the sampled set. That gives you a horizontal and a vertical view, from which you can extrapolate to a whole, or any other part, with some minor assurance of reasonability. If someone has an easier methodology to suggest, that still produces usable results, I’m all ears.
it isn't really germane to the conversation we're having.
I thought I’d made that point? -Bill
