Each packet either
1. terminates in my network
2. transits my network
3. originates from my network
Lets assume that I announce a price that I will charge other networks for
transitting packets through my network. Note, that I couldn't care less
about the speed at which they connect to my network.
Computers (third party?) on the edges of my network count the number of
packets that transit my network over a certain time period. Periodically I
issue invoices. Of course, other networks do the same. End users
(including co-located computers) simply appear as connected networks that
don't provide any transit, hence they pay for their connection.

Remember that I said "if the same amount of packets are transfered". The
speed of my connection does not necessarily affect the number of packets
that I'm transmitting.

No. That's "transmission cost", not "connection cost". The cost of me
connecting to your network (not counting setup and so on) is the sum of
the interface electronics on both ends and whatever link we need
Off on a tangent... creating bandwidth is somewhat like making computer
chips. Making the first production Pentium (or whatever) processor costs
billions. The second is a few cents. Here, laying the cable is expensive.
Once it is in the ground, the cost for transporting another packet is
An interesting question is what do to with potential bandwidth/cpu
cycles/free ram, i.e. what are the costs of not using available capacity?
One answer is that the cost is zero until your competitor starts being
more efficient then you are. See Soviet UNION vs USA.
Back to networks... it would be logical to assume that whenever people
deploy fiber they drop as much as they can afford at that moment. If
that's true then there must be enourmous amounts of unlit fiber. What's
the total capacity going accross the atlantic or pacific? How much of it
is being used? I'd bet that there are many terabits of fiber that are not
Yes, of course, the closer you get to what's technologically feasable,
(the closer you move to the border to the future) the more expensive
things become. I guess that's the main argument used to defend higher
costs for faster connections.
But we don't even need to go to that edge. Building gigabit, if not
terrabit routers is amazingly simple and can be done with off the shelf
technology. Hey, a few Linux boxes interconnected with a few 100MB/sec
ethernet switches in the right fashion would allow the creation of a super
NAP that should outperform gigaswitches easily.
Summary: I would not be surprised if the packet carrying capacity of the
Internet could be increased by two or three orders of magnitude with
surprisingly little investments. The real challenge is how to get people
to do that.

Hehe... you can, think about it.
