[arin-ppml] Demand for community networking

[Davis, Terry L]

I can only speak to design work going on for the Next Generation of Global Air Traffic Management Systems.

- Aviation has already agreed to use our air-to-ground link layer to isolate aircraft movements from the Internet routing should that ever be needed.

- At present the ATM network is being designed as a closed network (as our existing OSI network is) but our intent is to stay fully compatible and compliant with IPv6 standards.  So I don't see that as impacting nor do I see it ever be opened to Internet routing.

- Would it really be a great idea to have something like several 1000 individual IPv6 allocations to build the new global ATM on, if we include 200 nations, 500+ aircraft operating entities, a 1000 or so airports, plus aviation service providers of various types around the globe?  To me, that would be a nightmare scenario to try to design and secure a network to support any critical infrastructure.

Take care
Terry
