That seems odd given that the BEAM was designed for reliable real-time telephone switching

- tonyarkles 6y agoYou're not wrong! I actually tried doing a bunch of research to figure out how the original Ericsson phone switches worked with Erlang, but couldn't find a whole lot of info.
- imhoguy 6y agoAt least we have this "Erlang: The Movie" demo to reverse engineer some bits: https://m.youtube.com/watch?v=BXmOlCy0oBM https://m.youtube.com/watch?v=BXmOlCy0oBM
- tonyarkles 6y agoThat's awesome! Thanks!
- dnautics 6y agoIIRC a good way to put is that the phone switches didn't work with erlang, but the phone switch controllers did.
- jacquesm 6y agoSoft real-time != hard real-time. Erlang is great at soft real-time but does not work at all for hard real-time, there simply are no guarantees, just very good average latency. If you want hard real time (such as for in-flight control of a drone) then you should look elsewhere.
