You're a terminating, or 'eyeball', network if the preponderance of your customers are end-users, resi or biz. Small-biz networks that are single uplink count here, yes.
You're a transit network, if the preponderance of your customers are other networks, including larger business networks that are or might become multi-homed. In short, if the plurality of your customers have an ASN.
And for a chunk of time, we looked like a transit network for traffic that passed through us heading for Internet2, if you were looking at us from the Internet2 side, and damned few eyeballs unless you call a few dozen HPC clusters eyeballs.
But if you were looking at us from our Cogent upstream, we looked like an eyeball network because we didn't provide those downstreams any transit in Cogent's direction, so all that was visible was our tens of thousands of eyeballs that were all looking at stuff that wasn't on Internet2.
So as I said, it depends on where you were looking at us from.
What you *look like from outside* depends on whence you look, yes... But that doesn't affect what you *are*; my definition was based on the view of the mythical superobserver *above* flatland, who can see everything cause he's at right angles to it; the majority of ASs, I would venture to speculate, veer sharply in one direction or the other -- even if that's because a transit operator acquired an eyeball operator, or vice versa, and those parts are in separate ASen. Do we have disagreement on that point? I've mostly been above the forest, rather than in the trees... Cheers, -- jra -- Jay R.
