if you allow external peering anywhere, the need for tunneling to the one
and only border router at UCSD to go to Internet disappears since each
subnet can peer with any other local network, even at a local Internet
Exchange Point, and get transit to Internet locally. This means that a
specific subnet will not depend on the global Internet connectivity to get
to a local destination outside AMPRnet. The idea is to keep local traffic
local.
Actually, the idea is to keep the traffic routed and flowing. You don't
need TCP/IP if you want to keep it local.
We can use dedicated terrestrial wireless links at
different amateur
frequencies, amateur satellites or maybe even some dedicated wired
stretches (god forbid :-) if nothing else is available. On stretches where
we by no means can come up with a dedicated link, we can still tunnel....
The internal intradomain routing can be set up statically or using an
intradomain routing protocol such as OSPF in each AMPRnet island and, if
needed, export routes between islands using iBGP as opposed to the eBGP
functionality used in Interdomain routing.
I don't see this happening for long haul at all with the hobby in it's
current state. The usable bandwidth we have is all short range. The long
haul frequencies are heavily clogged and QRM'ed. We don't have high
apogee/geosynchronous satellites that have the capability to transport
megabits of traffic. The reality is that it is cheaper and faster to use
commercial networks for the long haul.
With the economy the way it is, there is no change in sight. P3E has been
indefinitely been shelved and it's based on something 20 years old already.
The cost of getting good repeater space is rising as the proliferation of
mobile devices climb. I see the reboot of amateur packet being thicker
locally with narrow corridors connecting cities. But that takes time and
money. In lieu of that, there is the Internet. Hence why I don't
necessarily agree with your idea of "44net has to only be routed by amateur
radio operations". It's not financially feasible.
