Re: Can P2P applications learn to play fair on networks?

* Eric Spaeth:

Of that group, only DSL doesn't have a common upstream bottleneck between the subscriber and head-end.

DSL has got that, too, but it's much more statically allocated and oversubscription results in different symptoms. If you've got a cable with 50 wire pairs, and you can run ADSL2+ at 16 Mbps downstream on one pair, you can't expect to get full 800 Mbps across the whole cable, at least not with run-of-the-mill ADSL2+. (Actual numbers may be different, but there's a significant problem with interference when you get closer to theoretical channel limits.)
