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.)
