Cerf Says Symmetry is Beautiful

Of course, from a technical point of view I am all for symmetrical connections as well.

From a commercial perspective I think that it's hard to recouperate cost

from a 10 meg symmetrical connection when the customer is running p2p and is using most of that bw 24/7 and is only paying $40 or so for that pleasure. Yes, one can degrade that customers performance by ratelimiting or such, or prioritizing other customers traffic or something else, but the 90/10 rule saves some of it, the problem is when the 90% start doing the same, then the flat rate business model is a problem and does not scale.

Where does 95th percentile fit into this?

i think the right rule is, "if you can't make money from it, don't sell it."
