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 real-world 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.
Connext DDS Micro is the first connectivity software designed for resource-constrained applications in real-world systems. It provides a small-footprint connectivity framework for IIoT devices that have minimal memory and CPU power, and that may not even have an operating system. Connext DDS Micro simultaneously satisfies demanding real-time performance requirements with meeting stringent resource constraints. By abstracting out low-level networking and communication details, it reduces development costs to minimise the amount of custom connectivity or integration code that developers would otherwise have to create.
Provided as portable source code with minimal operating system dependencies; example ports available for all common CPUs and operating systems, as well as bare metal devices with no OS.
All memory utilisation is fixed based on resource constraints; no dynamic memory allocation is required; efficient serialisation and compact wire representation also minimise CPU and network overheard.
Standards-based solution based on Object Management Group Data Distribution Service programming interface and RTPS wire interoperability protocol. Complies with DDS Security and demonstrates interoperability with other DDS implementations.
