Like, imagine you're a tier1 ISP and some small tier3 fiber-to-home ISP wants to buy transit from you.

Their last mile is skewed towards download, so the end users physically can't upload more than half their max download speed, and they likely won't upload much anyway unless they're into torrents.

So you'd be getting like idk, 8 Gbit/s download and 0.8 Gbit/s upload from that customer? Do you charge them for upload & link only?
