Interesting paper, thanks.? I'm sure that Peter and the EU bureaucracy
were very aware of the X.25-related costs and struggling with how to
allocate them (moving expenses into someone else's budget...).? But I
see no indication that they were aware of the asymmetry introduced by
our cost-avoidance algorithm.? E.g., did they ever compare notes with
the ARPA billing department??? Or did each side just pay its bill and
perhaps figure out how to allocate costs among the users on their side.
It also appears that they might not have understood how the costs
depended on who initiated each X.25/X.75 circuit setup - which was not
necessarily related in any consistent way with the TCP connections or
source of packet traffic.
Given all of the other usage of X.25 in Internet-related worlds (CSNET
etc.), there's likely a fascinating bit of Internet History in how
different systems dealt with the intersection between the Internet-style
"it's all free if you're approved to use it at all" and the X.25 "if you
initiate a conversation with someone, you pay by the minute and by the
packet" attitudes.?? Did anyone else implement "move your expenses"
schemes at organizational boundaries?
There's probably a PhD thesis or two to be done in that early-Internet
arena - Who Paid For The Internet?
