I think you're over-specifizing Bill's assertion, Woody.
He didn't mean "TCP Flows", I don't think; he was simply -- as I=20
understood him -- talking about the 40,000ft view of connections between
pieces of the Internet.
I don't expect your dataset to have flow-level data, and I don't think
he did either; it isn't really germane to the conversation we're having.
