All this talk about symmetry and asymmetry is interesting.
Has anyone actually quantified how much congestion is due to buffer bloat which is, in turn, exacerbated by asymmetric connections?

I think you might have the cart before the horse. If there's no congestion on a peering link, buffering doesn't come into play, at least not within the transport infrastructure. We're not talking congestion on the last mile side, we're looking at congestion on the interconnect links between networks, typically 10G or 100G ports. Unless you're running those links near or at capacity, buffering should be a complete non-issue. And if you're running those links at capacity, then the congestion is due to too much traffic, period, not to the size of buffers involved on either side of the link. ^_^; Thanks! Matt
