Feel free to plug any realistic source numbers into the formula that you please. The end result will have the same impact: the cost is nontrivial. If you want to challenge the methodology, I respectfully ask that you find someone who does cost analysis for a living to assist you with the particulars. I had a professional cost analyst review and validate it. Same guy who got the V22 Osprey canceled before Congress put it back.
Note that another hard to estimate number is the economic benefit of the Internet, but it is reasonable to estimate this as at least $ 200 billion / year, but probably 2 or 3 times that. The direct revenue estimates I could find were all > $ 200 billion / year.
So, the $ 2 billion / year to run BGP that you estimate is a cost of doing business no more than 1% of revenue, and probably more like 0.3 to 0.5% of Internet revenue, aggregated globally. Non-trivial, to be sure, but that level does not seem unsustainable or even unreasonable.
To put it another way, that prefix is worth the money. Regards Marshall
Shifting focus to IPv6 abandons the problem.Not really, since generally IPv6 routes and IPv4 routes are combined whencomputing routing load.If we do nothing, by what date do you expect IPv6 to exceed even 2% of the total routing load? I stand by my statement. Regards, Bill Herrin -- William D. Herrin ................ herrin@dirtside.com bill@herrin.us 3005 Crane Dr. ......................
