RTI Connext DDS Micro – Lightweight Messaging Solution

Small-Footprint Messaging Software for Resource-Constrained Applications

Connext DDS Micro is the connectivity framework for resource-constrained Industrial IoT applications. It meets stringent size, weight, and power requirements with performance, scalability, reliability and security well beyond the reach of traditional connectivity frameworks—all within a DDS standard-compliant framework.

 

Features

Connext DDS Micro provides a small-footprint modular messaging solution for resource-limited devices that have minimal memory, flash or CPU power, or even no operating system at all.

As portable source code with minimal operating system dependencies, ports are available for all common CPUs and operating systems;

  • Linux (x86)
  • Windows
  • FreeRTOS (ARM)
  • VxWorks (PowerPC)
  • devices without OS (ARM)

Connext DDS Micro uses an innovative, completely decentralised architecture. Applications directly exchange data in a true peer-to-peer manner – no servers, message brokers or daemon processes act as bottlenecks or single points of failure. As a result, Connext DDS Micro delivers the consistent low-latency, high throughput and scalability required for big data in motion.

Peer-to-Peer Communication
By utilising true peer-to-peer data exchanges, no servers, message brokers or daemons can act as single points of failure.

Plug-and-Play Communication
Devices and applications are automatically discovered and connected at run-time, allowing use in autonomous, dynamic and ad hoc intelligent systems.

Real-Time Quality of Service
Applications have comprehensive control over and visibility into real-time behavior, including timing, deadlines, resource utilisation and system state.

Optimised Publish/Subscribe
Data can be reliably multicast to multiple applications and devices for extremely efficient streaming data distribution.

Standards-based solution based on Object Management Group (OMG®) Data Distribution Service (DDS®) programming interface and RTPS wire interoperability protocol. Complies with DDS Security and demonstrates interoperability with other DDS implementations.
