In order for the Industrial Internet to work, a common language has to be established, enabling industrial machine sensors and actuators to connect to local processing, the Internet, as well as other important industrial networks in order to function as a single system.
A group of elite messaging technologies is emerging and PrismTech believes that the protocol able to power the Industrial Internet is within their ranks.
In their whitepaper called, "Messaging Technologies for the Industrial Internet and the Internet of Things," PrismTech, a software platform provider of DDS and a member of the IIC, reviews messaging techniques available that could potentially serve as the foundation of the Industrial Internet.
They focused on:
- Object Management Group’s (OMG) Data Distribution Service for Real-Time Systems (DDS)
- OASIS’ Advanced Message Queuing Protocol (AMQP)
- MQ Telemetry Transport (MQTT) a proprietary protocol originally developed by IBM but now a proposed OASIS standard
- Java Message Service (JMS) an international messaging standard developed through the Java Community Process (JCP)
- Representational State Transfer (REST) a common style of using HTTP for Web-based applications and not a standard
- Constrained Application Protocol (CoAP) is a software protocol to be used in very simple electronics devices such as Wireless Sensor Networks (WSN) that allows them to communicate over the Internet.
The criteria used in this white paper to determine which is the best messaging technology for the Industrial Internet include examinations of each protocol's interoperability, qualities-of-service, performance, security and more. PrismTech argues that, "An understanding of the architecture and the message/date sharing requirement of each target system is an important pre-requisite for choosing the most appropriate messaging solution".
After a thorough examination, PrismTech puts forward the opinion that DDS is the best protocol to adopt for the Industrial Internet. PrismTech explains, "Only DDS can provide the real-time, many-to-many, managed connectivity required by high-performance device-to-device applications. DDS is also emerging as a key interoperable messaging protocol for connecting real-time device networks to Cloud based Data Centers."
