Dave,


This list has had some interesting chat of late about the threat posed by
CU-SeeMe. (I know you're already on the list.) This message has some
especially interesting data about European long line costs and a
wonderful tag line by the sender.


Regards,
Dan

I've been lurking on this list for a couple of weeks, and I'm quite
happy to see that bandwidth consumption is being of concern to people.
From our (EUnet's) perspective, CU-SeeMe actually poses a serious
threat to the quality of the services we can offer, and we have been
considering various means of protecting ourselves and our customers.

trans-Atlantic bandwidth. BUT is this true for fee paying access?

Speaking as the person who evaluates, plans, implements, and controls
the transatlantic bandwidth for -- no holds barred -- Europe's biggest
commercial ISP, bandwidth is certainly going up and up.  We double
every six months.  But ...

 In the UK this is certainly not the case and the commercial internet
providers
are steaming ahead with their parrallel networks and their own funded
trans-Atalntic links. This may contain the germ of a bandwidth
solution... if
these commercial internet access providers find that it is worth their
while,
they would certainly find it commercially sensible to fund local reflectors
rather than invest ever increasing sums into long haul high bandiwdth comms
circuits. The network of reflectors solution seems the correct way to
go but
quite what it will eventually look like is unclear to me.

.. local reflectors and/or whatnot doesn't solve the situation
where somebody with a Mac behind a 64k (or even 19.2 async) link goes
to the US (or elsewhere in Europe, for that matter) and turns on what
can only properly be described as a megabit-blast (which happens a
couple of times every week).  Even if they had the local bandwidth to
receive it, I don't think they would be prepared to pay for it.  In
order to serve these people, we would need to have a separate 1-2Mbit
transatlantic link, just for their video.  2Mbit transatlantic plus
_one_ 2Mbit link across Europe costs on the order of USD
100000-150000 per month, just for the lines themselves; we'd need to
have separate 1-2Mbit links across Europe to every single country we
serve (over two dozen), simply to avoid CU-SeeMe tearing apart
regular traffic (telnet, ftp, WWW, customer-specific applications,
etc).  Obviously, this is not an issue open for discussion.  Were we
to bill people for their usage, it would easily come to USD 50-100
per hour.

For the benefit of US-based readers of this list who find this too
incredible, here are some examples of European vs US leased line
prices:

GBP 1 = USD 1.35, give or take 10-20%.

There's no question that CU-SeeMe is a great tool, great fun,
and a wonderful step forward (although I've never used it myself :-).
But careless use can have devastating effects on the networks
used for the transport.  As mentioned, wee see this happening
once or twice every week.

My personal guess is that unless something is done to ensure more
"socially responsible" use in the US, the problems we have in Europe
now will become widespread in the US in 6-12 months time.  Rationale:
At the current level of CU-SeeMe use European and transatlantic lines
are ready for meltdown, while in the US (where lines typically are 10
times bigger) one observes "busy day".  When CU-SeeMe use has reached
10 times its current level, one will in the US have to solve the same
problems we in Europe have to solve over the coming 6-12 months.

Imminent death of the Internet _not_ predicted, BTW. :-)
