[HamGateNY] Statewide Networking Ideas

[Charles J. Hargrove]

Happy New Year 2021 to all.  Time to forget about the 2020 crap, ignore
the clueless politicians and media and just live our lives!

Here is an idea on how they are building out their network in Slovenia.
Maybe there are some good ideas that will catch your fancy.


Maybe a concrete example of our current and future S5net in Slovenia 
together with our expectations from broader 44net community could help.

As you can see from schema of current and planned links:

    https://groups.io/g/nbp/topic/s5net_stanje_in_plan/79358609

we are building nationwide radio network, linking our hills with DMR 
repeaters into a fully redundant network, as much as possible 
independent from public internet. Main goals:

- reliable DMR, EchoLink, APRS network,
- emergency communications for our communities,
- for radioclubs and individual radioamateurs,
- open for experimentation and innovation into the future.

Besides mesh-like radio layer there is also a star-like ground layer 
connecting gateways to public internet via tunnels to main router in our 
capital. VPN server is established to connect easily and from everywhere 
to the S5net. Offering L2TP and SSTP VPN access which is easiest for 
most people.

We are using Mikrotik routers and Wifi antennas from Ubiquiti and 
Mikrotik. But we care not to become too dependent to any vendor. 
Sticking to standards is a key here.

We allocate our 44.150 IPs in the following way:

- /28 with reserve /28 to each hill,
- /24 with reserve /24 to each interested radioclub,
- /28 with /28 to a LAN of each interested radioamateur,
- static /32 and dynamic /32 (like for mobile phones) to each interested
- more for specific needs (for experimentation, some IoT projects etc.)

Allocation is not forever, it will probably cease 5yrs after inactivity.

OSPF protocol routes traffic in S5net. Therefore we are free to raise 
any subnet anywhere in the network. For things like roaming..

BGP to the public internet for a whole national 44.150 allocation is 
something we are thinking about. Like in Netherlands as I understand? 
All access from outside disallowed by default, switched on manually for 
each individual IP or subnet.

For peering we are talking with our Academic network ARNES, because they 
are similar in philosophy and have a lot of knowledgeable networkers 
willing to help.

To interconnect with HAMnet in neighbor countries we also plan to use 
BGP with a whole S5net as one AS with private ASN.

Our DMR master server is multihomed - with public access for hotspots 
and with 44 IP via S5net for DMR repeaters.

Hope this helps a bit
