Neither. We charge the peer whose traffic is incoming and who uses our
transit resources, a.k.a. intercity links. The peer always has control
over the traffic because they can route it differently if they choose or
build network infrastructure to avoid excessive use of the other company's
intercity links. We don't care about the peer's customers at all and have
no idea what is in the data packets. They are just bitstreams flowing in
both directions.

Much, much too complex. If the packet comes into my network, I note which
peer it came from, what is it's destination address and how many bytes in
the packet. At my leisure, I count the bytes and compare with outgoing
bytes. If it exceeds a predetermined ratio of free balanced peering, I
apply a selection algorithm to look at destination addresses and byte
counts and calculate a transit value. This is what I bill. Of course, in
the real world the collection of data and the billing would be audited or
even performed by a 3rd party settlements council.

I don't care about you; you're just a customer. The peering relationship
is strictly between the two backbone providers.
