A7: #DDS tops Data Connectivity Standards for the #IIoT #IIC24 #IoTDay #IoT #InternetOfThings

What is the communication interaction pattern or patterns required? For example, request-reply, which makes for tightly coupled interactions and is commonly used on the control plane of a system, or alternatively more loosely coupled publish-and-subscribe style communications that is typically used on the data plane. What is the desired level of interoperability between systems? Each protocol supports different levels of interoperability for information exchanges between applications and subsystems. For example, protocols such as MQTT enable basic syntactic (also referred to as Foundational Interoperability) whereby systems can exchange messages but how to interpret the data contained in each message is undefined. More sophisticated protocols such as DDS support full Semantic interoperability. Not only can subsystems exchange information but DDS takes advantage of both str...
