How does it look when you examine it by not the count of sessions or links but by the volume of overall data? I wonder if it may change a little like 50% of the volume of traffic is covered by a handshake. (I made 50% up - could be any percentage.) Jason

I quoted a PCH peering paper at the Peering Track. (Not violating rules, talking about myself.)

The paper is: https://www.pch.net/resources/Papers/peering-survey/PCH-Peering-Survey-2 0 11.pdf

I said ³99.97%² of all peering sessions have nothing behind them more than a ³handshake² or an email. It seems I was in error. Mea Culpa.

The number in the paper, on page one is, 99.52%.

Hopefully everyone will read the paper, and perhaps help create better data.
