and ask what judgements it is sensible to make given these trends.
First, let's see what Cisco believes is going to happen to
What is driving this growth?
Largely video applications of every sort -- VoD, HD
Videoconferencing, Internet TV, HD image transfer for medical
applications, PVR downloads, distance education, etc.
As Cisco observes, the continuing increase in screen resolution
and the steadily increasing power of processors means that
people are going to be more inclined to be running multiple high-
bandwidth applications concurrently.
Next let's have a look at some history (Slide 2). Here I have
Lucent has used.
It shows the downstream bit rates since 2,400bps V-series
modems came into general use back in the late '80s.
Should we assume that the trend will now roll over (red band) or
continue (green band)? I would not put my money on the red band.
If we believe the trend will continue upward as shown in the
green band then it makes sense that the Government initiated this
major project, since a wholesale FTTP network of this sort cannot
be built overnight.
I said I would not focus on applications, but I will use just this
one slide (Slide 3) to illustrate the types of applications that will
become available as access speeds increase.
When we get to the point where 3D collaboration and full
to provide the speeds required.
It is not just the Australian Government that has recognised the
taking place in our region.
Five of the six are providing speeds of 100Mbps or above.
productively use 100Mbps in the years ahead.
Now to the second question.
