Many of the bits that flow flow over several networks between their =
source and destination. Likely the vast majority of bits traverse at =
least 3 autonomous systems in the process.
So when you want to count traffic that went over a non-contract peering =
session vs. traffic that went over a contract peering session, how do =
you count traffic that traverses some of each?
