Alerts: Not looked into them very much, if they send an email to the operator that would work. Relying on the operator looking at the right part of the web interafce or the LEDs isn't good enough. I sometimes don't loook at the web interface for weeks and the controller is up in a loft out of eye and ear sight...
Yes, UDP is "send and forget", however I think all the data for a single signal fits into a single packet of 1.5 k bytes ish. So you don't need the overhead of the TCP error checked/retransmission system to ensure that all the data of a signal arrives. It all does, or doesn't if the packet gets lost. Assuming any packet loss is random acros stations, losing packets isn't going to have a great impact on the network. Say 50 stations report a stroke and 15 are needed to located it, 35 can get lost...
