A lot of military comms are point-to-point or broadcast between radios where TCP/IP doesn’t really make sense. On top of that, you need to understand how much legacy military networking stuff is out there. This stuff long predates the internet. We had tactical data links and target tracking where a ground station could receive a target info from a remote radar array, and automatically direct fighters on autopilot on…

I never said anything about mandating TCP too.

DDS sort of took over from CORBA in the military domain, and the statically-typed IDL was still quite similar to CORBA last time I looked at it, so that takes you back to around 1998 when CORBA was being used a lot in the military in my experience. What other protocols and systems were you thinking of that can provide (depending on broker) hard-realtime delivery that can be used in safety-critical systems?

Stupid question, but why didn’t the DOD mandate IP compatibility for literally all comms like 20+ years ago? Is it pure corruption/incompetence or is there a good reason?

why the hate on DDS? seems like a perfect fit.

DDS is the least bad of the stuff that has come out of OMG, but it's not a nice middleware still. There is no underlying algebra of that composes nicely when compared to Zenoh for example, and the "vendor independence" and compatibility is usually a joke. There's a reason ROS is moving away from it again.

“Hi Codex, please find attached website about the specification of my Battlesuit and use the documented API to create a plugin for Home Assistant that shows groups of sensor data. You are only allowed to use commands that retrieve data, you are not allowed to perform actions on the suit. Treat the suit like its API is not robust and in worse shape than a cheap toy: perform read calls slowly and sequentially with at l…
