Edge graph or connectivity map
Hi,

I just wanted to bring up two related concerns. Firstly, although I am aware that a node map exists, I was wondering where or if one can find a map of the routes, node edges, or the connectivity links -- whatever term you prefer. Secondly, I expect that after arriving at such a map, we will find that the network consists of a number of isolated islands and I wanted to ask whether there is any initiative to interconnect them to form a national network, and whether any effort could be organized to that end. I think benefits that come to mind with redundant national broadband are things like the distribution of ebooks for guidance in times of emergency, or the ability for hospitals and medical staff to exchange large imaging files, like the 3D x-rays they have now.

Thoughts or commentary are welcome. I was thinking about developing a tool to map the network if no such thing exists already.

Network mapping
There are several AREDN network mapping tools out there.   Here's one:  https://mapping.kg6wxc.net/meshmap/#8/33.970/-118.200 .   It's Open Source so the software is available at https://gitlab.kg6wxc.net//

As far as a national network, AREDN runs a global tunnel server and regional networks can request a link via Darryl, K5DLQ, here on AREDN.

Redundancy

The tunnel service is great, but I think it's clear how relying on the Internet defeats the purpose of network independence and redundancy. That maybe fine for very localized emergencies, but it does nothing for you if there is a widespread outage of telecom service.

Tunnels
Of course - I tell all the local groups not to plan on relying on tunnels.  Your served agencies need to be on solid, robust RF links before you can even think of offering EmComm via the AREDN network.
