That is one thing I don't understand about the aversion to peering. We
peer with anyone who will either pay the line costs or connect to us over
Bell FR, where the costs are negligible. Granted, we are small potatoes in
the ISP field, but to my way of thinking both parties benefit. There is
a customer here communicating with a customer there. Both ISPs are getting
money from their customer to get connectivity to the other ISP's customer.
Dropping the peering connection degrades connectivity for both ISPs'
I understand that there is a an issue about a smaller player using the
larger player's long-haul links for transport, but in this case it seems
that Exodus is neither a significantly smaller player nor are they using
BBN's links for long-haul. In fact, it seems that if Exodus were to purchase
transit, all that traffic would be moved to a single peering point between
BBN and whoever they purchased traffic from, which *would* be using BBN's
long-haul network. Not to mention that the asymmetry of that link would
become the same level of a "problem" as the current links to Exodus.
I don't expect that a small ISP like ourselves could go to any of the major
ISPs and expect to peer for free, but in this case it looks like BBN gets
at least as much benefit as Exodus of the current arrangement.

More likely they think they have Exodus/etc backed into a corner with no
option but to pay BBN for transit.
