I think your xlx example is not the best for the use
case of 44net
addresses.
It's a good example of pure HAM application not using 44net addresses
because of 44net current topology.
For efficient routing and high speed and low latency
as required for
voip systems, it is much more efficient to do a direct connection to
the server on a public interface instead of doing it the 44net way
unless the server sits on a BGP announced subnet.
Our XLX is using 44.190 IP adressing. Following DG8NGN rules, it's
routed directly to Internet from our data center. Reaching it via its
44.190.11.6 IP address, or via public Internet address, is currently the
same latency. Some people are using dual addressing (44net and public
Internet). We dropped public Internet completely, and are using only
44.190 IP addresses.
Yes, a 44 BGP network would do the trick, but I am certainly not
willing to pay hundreds of USD per month for such an endeavor. BGP
peering is not cheap and not readily available in the whole wide world
unless it is not piggy backed on another preexisting AS for a select
few working in the network business.
Several people here are using Vultr VPS. Our instance costs $5/month,
but the $2.5/month instance would do the job, too. Setup is very easy.
Also, as said before, we now can afford some operational costs for
network infrastructure.
And even in this case, it is of no use for the client
to have a 44net
address, since it will again need to go the ampr-gw route to take
advantage of that IP, while masquerading to the local gateway IP
would yield better results.
I do not really understand. The idea of a single ampr-gw in San Diego is
from the past. We are now thinking about the future. One idea would be
to install several POPs (Points of Presence) in several countries or
regional zones. That's what we did here, on our tiny island. We are
currently experimenting dual addressing :
- 44.168 : standard AMPr adressing, routed via current schemes; no
output to Internet, or output via the nearest local NAT gateway
- 44.190 : full Internet routing, via BGP, at the same cost as standard
Internet routing. IP addresses are announced in Paris (nearest Vultr
data center) then routed to our regional POP in Corsica via the most
direct path.
We should look into other things, not available or not possible on the
regular internet, and voip and regular services are not it.
That's an opinion ;-) But I have another one ;-)
VoIP, digital modes, SDR and other applications using computers are
enjoyed by many people, particularly the young ones. The most recent
commercial transceivers are SDR (ie, a computer), have Ethernet ports,
and use IP. On the other hand, we own a dedicated IP range. My opinion
is that every HAM application using IP should use AMPR addressing, or
should be able to use it easily. If we have a good routing policy, this
would allow to isolate what is pure ham radio (for ex, remote rig
control) from what is general purpose Internet. AMPRNet should work as a
corporate network, allowing members to communicate with each other, and
with the ability to limit / control gateways to wild Internet (required
by some regulations in some countries; this would help us achieve this goal)
