Keeps in mind that the aviation network will have 140+ designers and operators (each nation-state member) and only high level architectural guidance from ICAO at the top.   SIPRNET is a highly controlled environment and as I recall it still depends on traffic filter access lists on the routers to control entry.?

I think we will have similar problems with a "policy" approach.

Look forward to the discussions in Vancouver.

Take care

I am not sure that I agree with your first statement. Why couldn't you build a closed network using OTS gear that implements current IETF standards?  Are there not many examples of such networks (e.g., SIPRNET )?

The second problem is more interesting. The CIN might want to standardize a BGP policy with the following characteristics:

-          Enforces a globally agreed routing policy

-          Does not fail in a catastrophic way when one node/country does something that does not comply with policy

Two problems immediately come up with this path:

-          Current standards don't readily support the concept of closed or isolate networks.

-          And as any of you that operate large networks, especially globally with millions of nodes, know, they are always cross-wired somewhere.  And thus defining a scheme to protect the Internet BGP tables from disruption is going to be very challenging.  And don't forgot, there will not be a single network operator; most of the 140 nations will operate their own part of it.
