My take on this is that settlement free peering only remains free as long as it is beneficial to both sides, i.e. equal amounts of traffic exchanged.

Clearly, to balance out the traffic ratios, content providers should set their server MTUs to 64 bytes. That way, small HTTP request packets will be nicely balanced out by small HTTP reply packets. If the content providers also turn off SACK, and force ACKs for each packet, they can achieve nearly the perfect traffic ratios the eyeball networks seem to desire. Small packet one way, equivalent small packet the other way, and everyone is happy. Obviously those recent infidels pushing for the so-called "Jumbo Frames" here on NANOG were nothing more than shills for the eyeball networks, seeking to get more and more networks out of ratio, in an effort to get them to cough up money. Fie on them, I say--instead of JumboFrames, we need MicroFrames! Exchange points should start enforcing a maximum frame size of 64 bytes, to truly bring the internet into perfectly-balanced ratio-ness.
