" The argument can be made, and there might be empirical data to back it up, that the private interconnects actually offload *at least in the short term* the participants' pipes into the public exchange points. For example, if a significant fraction (1/4th to 1/3rd) of the S and M and ... traffic into a public exchange is S and M and ... talking among each other, then offloading much of it at some other place might reduce the fractions (maybe to 1/10th to 1/5th). Of course, if their business models do not include eventual upgrading of their pipes into public exchanges, they will have to balance the reduced <performance|reachability> to the Internet at large as seen by their customers against any savings from not upgrading. (Disclaimer: I pulled the numbers out of thin air, so anybody who quotes them is as foolish as I for having put numbers in writing in the first place.) --Steve - - - - - - - - - - - - - - - - -
