Replying to John a bit out of order...
BGP'ed regional networks provide more portals into
the larger Internet and
can support smaller networks via VPN and Tunnels.
For sure if we had more traffic it would be good to have multiple
gateways instead of the existing sole system. Then the smaller
networks could tie to each other via Tunnels and VPN to preserve the
reliability. (The real need for any connection between 44 net and
non-44net would be another good discussion...)
If the BGP is in a 'hardened' data center then
its probability of going
down is greatly reduced over the random tunnel server running on a 20 year
old computer in somebody's basement.
Maybe... But a few 20 year old basement computers 10 or 20 miles
apart running ampr applications is something special that we can do
and nobody else with no other technology can do.
You can multi-home BGP networks for higher
reliability. It all depends on
how the network is engineered. This is a volunteer effort, with
distributed network design and management.
Part of engineering is considering the 'volunteers' available.
Designing a system where only a select few can play (BGP routing) is
less HAM oriented, UM!HO, than a basement computer system where
anybody and everybody can participate.
However, I think a truly useful network of Amateur
Radio related
technologies is better served via high bandwidth infrastructure (99.99% of
the time). Ingenuity takes over for the rest (0.01%).
That high bandwidth infrastructure is generally not 'amateur RF' so
keep it simple and on the stock Internet technologies and no need for
any additional routing magic.
It's all pretty much moot given the lack of a use case for either the
BGP High speed or basement lower speed systems. I'm still dreaming of
a HAM Radio variant of Facebook...
