I was wondering when the discussion was going to take this
turn before I threw my monkey wrench (or "spanner", for you
on the civilized side of the Atlantic) into the works...
We've done some projections on TCP performance on the evolving
Internet, and while the results aren't ready to publish, they
are nonetheless startling:
As the Internet grows and more dial-up users connect
(currently the fastest growing community), we will
see increasing congestion on inter-IXC (and inter-NAP)
links on the "backbone" Internet. Result: most low-
bandwidth users (ie. less than 128kb/s) will never
have a window size greater than *ONE PACKET*.
Surprise! So, what's the conclusion? Well, most Internet
providers won't want to increase the bandwidth of the links
that connect them to their regionals, because there's no profit
in this (at least until users wise up and start bitching about
poor network performance, ie. 12kb/s ftps on a 28.8kb/s line).
Congestion will only get worse, even with the advent of
bandwidth-on-demand, such as ATM, frame-relay, or SMDS.
Alright, so where am I taking all of this reasoning? Most
of you people I suppose aren't interested in low-level
Just here: image scaling (ie. fitting an image into a
640x400 rectangle), depth reduction (taking a 24bit GIF file
and rendering it in 1bit deep B&W on a notebook), etc. should
be done *SERVER-SIDE*.
Now before you flame me, I realize this is unclean and not
the logical place to do this: the client should be
burdened by whatever presentational computation his
preferences entail. Sure. That's logical.
But should everyone be penalized by wasted network bandwidth
in transmitting images (or sound) in a format that exceeds
the possible capacities of the rendering hardware?
On the other hand, if I browse some images on the road with
my monochrome laptop, and these images are cached, then plug
my laptop into a colour monitor at work or at home at a higher
resolution and depth, the cache will be invalid, since the
images will have to be "refreshed" at a higher resolution.
Or at least, they should be. Of course, this is an admittedly
Am I the only one to lose sleep over these issues?
Should HTML 3.0 architects be concerned about the
economics of the Internet? And what will happen if they
HTML *is* after all the biggest consumer of bits on the
