It’s normally used for faraway tracking in IoT. DDS is decentralized. Evaluation focuses on how easy the protocols can be used and on how much work is taken away from the developer to be automated in the middleware for regular tasks like securing, searching, and serializing the data. In principle, placement on the socket adapter without the PDU header option or directly on the TCP/IP is therefore possible in the CP. However brokers can restrict access to topics. Like MQTT, DDS was designed specifically to address machine-to-machine (M2M) communication, the foundation for the IoT. Decentralized, peer to peer communication.

Download . Neither WMQ LLM or WMQ scales down to unreliable device networks and embedded systems, so there is WMQ Telemetry (aka MQTT), which was specifically designed for constrained devices and networks, and that can interoperate with the main queue manager, too. MQTT is optimized for centralized data collection and analysis – connecting sensors and mobile devices to applications running in a data center.

Requirements for turning on your light switch (best with CoAP) are much different than the requirements for managing the generation of that power (best with DDS), monitoring the transmission lines (best with MQTT), or communicating power usage within the data center (best with AMQP). So it’s about time to work on that alphabet. On May 13, 2013, at 12:20 PM, "Mike Milinkovich" wrote: Rick, “In the public domain” means something very specific from a legal point of view.
