[e2e] Free Internet & IPv6

I wonder why the bandwidth is unused in the first place?  Is it being wasted because it is of little value?  What bandwidth are we talking about?  I guess that bandwidth as a commodity would have a time and place.  Bandwidth on what router and when?

Is it bandwidth on the routers between the cat video community and youtube?  Or the bandwidth on some router that nobody wants to use anyways?

Maybe TANSAFL is not so easy to defeat.

So here's an idea - (pace, Bob Briscoe and Google Adwords)
Decongestant Adverts (DA - LikeCongestion Exposure, only backwards - employing Yet Another Level of Redirection called

bandwidth doesn't have much operational cost - te real cosrt is the shadow price of other people's traffic you displace - if there isn't other traffic, then the additional cost of carrying yours is little.

So we can have a receiver pays model for capacity - and the way they pay is via third party ads..
now this works very nicely if we observe thatcongesiton exposire requires you to transparently reveal where the congestion is - i.e. the source of ECN marks...

so the source can also reflect  the receiver to a wiling advertiser site, who then sends adverts with ECN-willing-to-pay marks ...
sine the adverts flow the opposite direction from the traffic they don't add to congestion - indeed on many links (e.g. Adsl) there's plenty of capacity that way anyway

that way, the net is free at the network layer, not just uo in the clouds
what say?
I see a bright new decongested future, full of IP banner ads

There's no technical challenge there. It's a business problem. Allocate some addresses from the existing pool and use them for a defined service such as you're describing.

What happens next, of course, is that since bandwidth costs money and no money is being exchanged, one gets no bandwidth. You've had the experience in hotels, no doubt; they offer free wifi in every room, by which they mean they have installed wifi APs on a LAN and connected that to some service provider. It works just fine as long as you send no packets on it. If you decide to send packets, oh, well gee. 20% loss is not a problem, is it? It's better than losing ALL of the packets, and after all it's free...
