What I am curious about here is the view from the big networks. A small
number of networks carry a very large percentage of the traffic. I'd like
to know what piece of their traffic actually crosses a public exchange,
rather than being delivered to a customer or another big network over a
private peering arrangement. The answer to this question will put some
level of relevence on this discussion. If those who carry 80% of the
domestic traffic exchange 80% of their off-network traffic privately then
NAP architecture and growth stratagem don't really make a difference.
