I agree and IP Multicast is something we can afford on
our 44net based
networks, which are without NAT and other limits for IPv4 Multicast.
For connecting DMR repeaters between themselves directly, in zero-cong
fashion, for instance. Without need for a central DMR master server,
which itself is a single point of failure. Its sole role can be to
coordinate traffic on talkgroups but the repeater network can learn
and communicate directly afterwards. Specially in case of master
server failure or network split of any kind.
I am especially interested in repeater linking via amateur IP
facilities. As I understand it, most repeater linking is over commercial
Internet connections, which is great except that you can't count on them
being there in emergencies. Besides, we're hams.
I don't know DMR's IP-level protocols, but if they can be multicast, and
the 44-net can support general multicast, that would be a perfect
combination.
This is an idea behind a DMR-Multicast project which is already
written and I hope I will start testing to release this winter.
Great!
