Subject: Finding real costs
Stan's comments are all perfectly sensible and to the point about
what was true than. They easily could be true today. The test is to
put in the real numbers and see whether the costs are "painfully high"
or "surprisingly low," especially at the large carriers who service 90+
% in the U.S., have fiber in place, but do need to add switches,
routers, WDM and similar equipment to deliver more bandwidth.
When I put in the best numbers I can find. I come to bandwidth
costs of 1-4% of the price charged the customer, and not increasing.
Traffic is growing fast, 25-40% per year per customer (Odlyzko.)
Relevant equipment costs are coming down about as fast. Carrier
spending on bandwidth per customer has been about flat.
Data and evidence wanted. I certainly could be wrong. Especially
as NN became a political battle, carriers are very reluctant to
provide real data even to respected professors. If anyone has the
direct bandwidth cost data, I'd love to see it. I'm specifically
speaking of large, wireline carriers. I know wireless has more
constraints and I am not expert there, cable local upstream has
problems at least until they go to DOCSIS 3.0, and smaller carriers
are in a bad situation. Christopher Yoo notes them in a brilliant
article he just wrote about the possible problems of NN, well-informs.
The key question remains, what are the costs at a Verizon, Comcast,
Cox or Bell? (up to the limit of the local access without digging,
such as the 25 down, 1 up of AT&T U-verse.)
There are probably people on the list who have answers. Please
find a way, perhaps anonymously via Dave or similar, to get us the
real numbers to inform this discussion.
