I point you to the notes of D.C. Nanog, particularily the Sprint discussion. http://www.academ.com/nanog/may1996/sprintlink.html#Notes I don't remember for certain the figures that Jim showed on the detailed map of Sprint's National backbone, but I do recall a 90%+ utilization figure on mae-east and mae-west links by Sprint. I'm sure many others are very near that as well. Don't mean to pick on Sprint, but they made that information public at NANOG D.C. I have no idea what the "intentions" are of the "big players". Don't even want to get into that, as the only people that know the real intentions, are those making the decisions not to upgrade their links. What is fact is: the IXPs are not over utilized.. the links of the carriers entering the IXPs are. ROb
In other words, the big players don't like the "open" naps and are deliberately not installing sufficient bandwidth to them?
