They were private peering stats (aggregated) from UUNET  which
show 3.5 x for roughly two years, right before the MPLS conference
in GMU.   The stats included 15% or whatever% ATM cell tax.  ANS
was not included;-)

There was also another dimension.  In addition to the vertical growth.
The backbone also expanded horizontally (coverage/millage), in a very
rapid pace.  I guess this was the reason some said the growth rate was
double digits.

I'm not sure simplify the math can explain the complexity of the network
growth.  Of cause, this is another topic.

I have a concern that your posting and your paper mix UUNet traffic with
the
Internet traffic.  I personally was very much involved in the ISP world
(was
working for Tier1 ISPs) during the period and I’d like to point out the
following:
UUNet’s (or any other individual network’s) traffic does NOT equal to the
Internet traffic, even at that time!
I was working at ANSnet and later UUnet due to a three party acquisition
deal
between AOL, WorldCom and CompuServe during that time period.  I did hear
presentations about network traffic being doubling every 100 days by O’Dell
but
my understanding was that he was referring to UUnet’s traffic not the
Internet
traffic.

At the time, the Tier 1 ISPs included UUNet, MCI Network, Sprint Network,
ANSnet, etc.  Each ISP could only collect network traffic stats on its own
backbone and there was no one entity could collect the entire Internet
traffic.
For this reason, the prediction by O’Dell could only be based on UUNet’s
traffic
stats.   I really doubt that O’Dell would say the Internet traffic doubling
every 100 days rather than saying that of UUNet’s traffic.   I’d encourage
you
to do some research to find out if he was really referring to the Internet
traffic or just UUNet traffic.  The reference listed by your paper showed
that
he was saying ‘network traffic’ not ‘Internet traffic.’

I do not know if making such distinction would alter the conclusion of your
paper.  But, to me, there is a difference between one to predict the growth
of
one particular network based on the stats collected than one to predict the
growth of the entire Internet with no solid data.
Thanks!--Jessica

Subject: off-topic: historical query concerning the Internet bubble

Apologies for intruding with this question, but I can't think
of any group that might have more concrete information relevant
to my current research.



Enclosed below is an announcement of a paper on technology bubbles.
It is based largely on the Internet bubble of a decade ago, and
concentrates on the "Internet traffic doubling every 100 days" tale.
As the paper shows, this myth was perceived in very different ways
by different people, and this by itself helps undermine the foundations
of much of modern economics and economic policy making.

To get a better understanding of the dynamics of that bubble, to assist
in the preparation of a book about that incident, I am soliciting
information
from anyone who was active in telecom during that period. I would
particularly
like to know what you and your colleagues estimated Internet traffic growth
to
be, and what your reaction was to the O'Dell/Sidgmore/WorldCom/UUNet myth.
If
you were involved in the industry,
and never heard of it, that would be extremely useful to know, too.

Ideally, I would like concrete information, backed up by dates, and
possibly
even emails, and a permission to quote this information.  However, I will
settle for more informal comments, and promise confidentiality to anyone
who requests it.

                  Preliminary version, August 5, 2010


                            ABSTRACT

  Gullibility is the principal cause of bubbles.  Investors and the general
public get snared by a "beautiful illusion" and throw caution to the wind.
Attempts to identify and control bubbles are complicated by the fact that
the
authorities who might naturally be expected to take action have often
(especially in recent years) been among the most gullible, and were
cheerleaders
for the exuberant behavior.  Hence what is needed is an objective measure
of
gullibility.

  This paper argues that it should be possible to develop such a measure.
Examples demonstrate, contrary to the efficient market dogma, that in some
manias, even top-level business and technology leaders do fall prey to
collective hallucinations and become irrational in objective terms.  During
the
Internet bubble, for example, large classes of them first became unable to
comprehend compound interest, and then lost even the ability to do simple
arithmetic, to the point of not being able to distinguish 2 from 10.  This
phenomenon, together with advances in analysis of social networks and
related
areas, points to possible ways to develop objective and quantitative tools
for
measuring gullibility and other aspects of human behavior implicated in
bubbles.  It cannot be expected to infallibly detect all destructive
bubbles,
and may trigger false alarms, but it ought to alert observers to periods
where
collective investment behavior is becoming irrational.

  The proposed gullibility index might help in developing realistic
economic
models.  It should also assist in illuminating and guiding decision making.
