The rough numbers suggested that the attributable economic cost of one IPv4 prefix in the DFZ (whether PI, PA or TE) was then in the neighborhood of $8000 USD per year.I haven't seen that work, but I am guessing this number is an aggregate (i.e. every cost to everyone on the 'Net combined), not per- network? See, I'm just looking at that TWO BILLION DOLLARS PER YEAR number and thinking to myself, "um, yeah, right". :)
Patrick, That was a worldwide total, yes. The cost per prefix per router is obviously only measured in cents per year. You do know that Cisco's sales are north of $20B per year, right? Juniper, which sells few products that aren't DFZ routers, also posts annual revenues well north of $1B.
Feel free to explain how confused I am. (But be warned, I am not going to believe it costs $2B/year to run a multi-homed network with two full feeds. :)
The thread started here: http://lists.arin.net/pipermail/ppml/2007-September/008927.html It was originally an argument of about the cost of doing PI for IPv6, which according to Cisco product literature consumes twice the amount of space in the FIB as routes for IPv4. I encourage you to critique the numbers and then add them up for yourself. Regards, Bill Herrin -- William D.
