Hi John,

Thanks for the post.

I myself have 35 years continual experience in the field of professional computing.

Could you possibly share with me what your best estimate of your own
internet bandwidth requirements were 30 years ago?

Could you also possibly share with me, with respect your own usage, what you
would have regarded in terms of bytes as being "a reasonably large file"
30 years ago and what you regard as a reasonably large file in your work
today?

Alternatively, could you possibly recollect what your hard disk storage requirements
were 30 years ago and what they approximately might be today, including
any stored in "the cloud"?

If your experiences are anywhere like most Australians, I am sure your requirements
for bandwidth, storage and computing speed will have exploded during this period.

For many IceInSpace readers, their bandwidth and storage requirements 30 years
ago may have been zero.

Cisco have a web site that provides their own forecasts for networking
in key regions of the world here -
http://www.cisco.com/web/solutions/s....html#~Country

In Australia they currently estimate that peak Internet traffic will grow 2.9-fold from
2012-2017, a compound annual growth rate of 24%.

In 2012, they estimate Internet traffic in Australia was 282 Petabytes per month
but will grow to 650 Petabytes per month in 2017.

They estimate that Australian Internet traffic in 2017 will be equivalent to 85x
the volume of the entire Australian Internet in 2005.

They also estimate that in 2017, the gigabyte equivalent of all movies ever made
will cross Australia's IP networks every 8 hours.

That is incorrect. The primary bottlenecks are in the last mile.

The Australian city links already have a fiber backbone.

According to Southern Cross Cables who operate a network of 28,900 km of
trans-Pacific submarine fiber optic cables including links between Australia and
the United States, current available bandwidth capacity between the two countries
is in excess of current demand.

In their own words, installing successive generations of transmission technology to
each end of the cables has been comparatively easy and inexpensive.

For example, in 2008 each of their cables had a capacity of 120 gigabits/s.
By the end of 2012, by upgrading the transmitters, each had a capacity of
1000 gigabits/s (1 terabits/s).
