What's so bogus about wanting to charge for traffic?
Where I would raise a flag is, charge whom ?
This sounds very much like the way that international long distance used to
be done. That the Internet does not support that is to me, at least, not a
bug but a very desirable feature.
And you can get into transit charges. How much does Country B charge for data
from Country A going to Country C?
Oh such FUN!!!! Shades of X.25 gateways! Oh, oh, and Teletypes. Oh yes it was
SOOO much fun working out the best way to route messages back in my
Automotive days... We need X.400-style routing tables back!
I think this is at the heart of it, and why I'm taking it very seriously. This
isn't about netflow or netflow++. As we all know, pairwise (peerwise?)
settlement payments are quite common. But the only reason to put charging
information into BGP is to enable -- and require -- much more complex payment
regimens. From a government perspective, it might about about setting prices
high for traffic from, say, an AS that hosts content they don't like. From
some folks perspective, it might be "the" answer to the network neutrality
debate: they don't discriminate, they just want to be paid by the sender. It
would discourage folks who host or post too much content, or run services like
Tor for free.
I don't think this idea is coming from people who don't understand the Internet
or its current economic models. I think they understand it all too well. I
think this is a thoroughly bad idea that really should be stopped dead in its
tracks, both for policy reasons and -- see rgm's comments -- technical ones.
(Here's another amusing thought. Imagine that a charging rate announcement is
denominated in Elbonian zorkmids. Do you want to download foreign exchange
tables into your BGP preferences configuration?)
