Oh also I forgot to mention that trying to map a direct relationship
between IX traffic growth and total IP traffic growth is completely
bogus. There is a significant modifier you're missing, and it's called
"price". Two years ago the price for an IX port at the large commercial
exchange points in the US (which account for the vast majority of the
traffic, no offense to the small non-comercial exchanges out there) was
between 4-7x higher than the price for the same ports today. The reason
for the price drop had nothing to do with changing economics of
providing the service, but rather it was because of a wide-spread price
war between the two largest IX operators in the US. Such a massive
change in the economics for the IP network operators will obviously
result in major changes to the amount of traffic delivered over IX
fabrics vs private interconnection. Again, something you could have
actually asked operators about rather than making up conclusons in your
head.
