I realize the scheme is old, I myself reinvented it around 1990. I guess give that the idea hasn't gone very far since kind answers my own question.
My view at the time -- and my view today -- is that there's an inherent conflict between that and multiple competitive ISPs.
It'd be a standard. Surely people were thinking that before TCP/IP suite became dominant speaking a particular protocol was a competitive advantage against a competitor.
Suppose there's an IP address corresponding to 40.75013351 west longitude, 73.99700928 north latitude (my building, according to Google maps). To which ISP should it be handed for delivery? Must all ISPs in a given area peer with each other?
Let's say I buy a mesh radio which speaks the protocol. Who's the ISP? By putting it up on a pole or a roof I've become a transit point for traffic which potentially originated far away. I could use QoS to prioritize traffic by distance, so that far away traffic doesn't expire. In larger networks, you could tag packets with your ISP's tag, until it is being delivered to a "closest" point (of course geographic distance is not a single metric) of exchange. That way you could guarantee traffic doesn't exit your network unless it hasn't got any choice. Of course you could tunnel anything you want over a geographic link. Any LoS laser satellite constellation would presumably do that. -- Eugen* Leitl <a href="http://leitl.org">leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE
