    Reminds me a lot of the Tactical Microgrid Standard (aka TMS aka MIL-STD-3071) [1], probably just because TMS uses DDS as well. I would really like to know if there is a protocol that functions like DDS but caters to real-time guarantees and prioritizes (at a "simple protocol" level) usability on embedded systems with no dynamic memory allocation. It would also need to be just-as-functional with non-real-time systems. One problem with DDS is that it is too heavy-handed to implement well on an embedded system.

      Pretty sure there are DDS implementations that provide most of that, maybe with memory pools instead of no-allocations.

      Other than that, PX4 uses an in-memory only pub&#x2F;sub for internal data bus, somewhat inspired by DDS

        I should have also mentioned that my appetite also includes not being locked into one vendor&#x27;s software stack. For instance, there are nice offerings from Eprosima [1] and Twin Oaks [2] that do this, but they seem to be &quot;outstanding in their field&quot; and would be difficult to replace if a need to do so developed. In the case of Eprosima&#x27;s offerings, they also make some architectural assumptions that are difficult to maintain for some applications (such as having a paired Linux device with each embedded device acting as a translator).

        But yes - there absolutely are solutions already. I guess I was just lamenting that they weren&#x27;t really functionally accessible for all applications.
