Larry, this is indeed a loosely coupled /system/, not a loosely coupled /network/. In other words, it is up there in the application layer. The network layer for it can and usually is a controlled latency and response time one. The DDS origin is in the air-force where it rides on top of a doubly redundant bus, the MIL-STD-1553. By today's standard this is indeed old-fashioned. However, thousands of aircraft are using it daily, by many countries, and I doubt that any other network can claim that many flight hours, literally... The CAN network has the aspirations to apply the lessons this network taught us but with more pep.

This can be a powerful tool, but it is not a silver bullet. It does provide a way to build loosely-coupled systems, but they are built around a shared data paradigm. I get nervous when I hear something like this described as "real-time" in particular, since that is antithetical to both networked communications and loose coupling. Larry M.

This is an awesome breakthrough in messaging! I wish I would come up with such a brilliant idea. So simple and so powerful! (BTW, the M2M moniker can also be interpreted as "Many-to-Many".) And (one of) the beauties of it is that neither message originator(s), nor the message recipient(s) need to be aware of the design of each other, not even of the existence of each other. This is great for system upgrade. Think of a system initially comprised of just a GPS and a car navigation system that is later upgraded with a magnetic or a gyro compass. The only change necessary is for the navigation system. It needs to "subscribe" and of course use the newly added information for better navigation. The other two are oblivious of the consumer of this new information.
