garage out there, 20% loss starts to take on a whole new meaning...
Or this one? :-)
Just curious, but how was that figure arrived at?

This one. Seems waaay too high. I don't think 1/3 all global Internet traffic passes through _all_ of public exchanges, let alone one exchange. -dorian
A talk I heard a few months ago said that 85% of the statistics shown in presentations were just guesses or made up. Probably the same is for email postings.
Stastics show that its possible to statistically prove anything.

As one of the few people who has actually gathered some statistics about the net, change that to "just guesses, made up, or real numbers drastically misinterpreted" and I'll agree 100%. *grin* ********************************************************* J.D.

Seems waaay too high. I don't think 1/3 all global Internet traffic passes through _all_ of public exchanges, let alone one exchange.
If we're talking about WAN traffic (not all IP traffic), then my estimate is about 70% going through an exchange point. Given MAE-East's central location, 33% seems to be not that far off the mark (definitely not orders of magnitude). 10% maybe. --vadim
There is a non-trivial amount of WAN traffic flowing between ISPs' private interconnects. They do not touch NAPs at all. I wonder if this factor is taken into consideration when the 1/3 figure was generated. --jessica Date: Tue, 21 Oct 1997 17:27:42 PDT To: "Dorian R. Kim" <dorian@blackrose.org> cc: "Paul G.

I'd tend to doubt it. Do you know any way to get flow stats from every backbone collected in one place and collated? ********************************************************* J.D.

So you do not think that the estimate include the traffic exchanged at private interconnections either. If this is indeed the case (which is very likely), the figure is not that meaningful.

I'd think most of the backbones have stats data of its own private exchange(s) but I do not think it's publicly available. --Jessica
