Excuse me, but bandwidth demand doubles in about half year,
while Moore's law is that semiconductor capacity doubles every
2 years. There's no indication that this will change any time

Nice brick wall :slight_smile:

I doubt it. The curve is racing upward now because of all the people
who are suddenly connecting to the net. Once a large fraction of them
are on the curve will slow dramatically -- demand for bandwidth will
continue to increase, but only as fast as the customers can eat it,
which is by definition related to how fast their equipment runs.

This whole thing is very reminiscent of what happened with fax machine
production a decade or so ago, and what happened with phone installs
about a century ago.

There will be some problems between now and the time things slow down,


Networks are by definition designed for one computer to talk with many
other computers. Under the ideal situation the computers would talk to
each other at the same speed it talks to its self (bus bandwidth, memory
speed) creating a single virtual computer. Due to the engineering
constraints of doing this, using the bandwidth that is available,
applications have been written that are "network specific" eg. slow. This
constraint will always drive bandwidth to higher speeds. Thus it follows
Moore's Law as chips get faster, so will computers and conversly -
bandwidth. There is no end in sight for the need of more bandwidth.
