RTI Connext DDS

Connectivity Software for Industrial IoT

Fast • Scalable • Resilient • Secure

The Connectivity You Need to Control and Monitor Demanding Industrial IoT Systems

Develop Connected Apps and Devices

Simplify communication with high-level APIs for data-centric publish-subscribe, request-reply and message queuing. Libraries support all major programming languages and operating systems - even bare metal.

Integrate Everything

Connect new and existing assets with a fast, scalable and secure integration bus. Easily adapt to disparate protocols. Write apps to a unified API and data model decoupled from underlying devices' native interfaces.

Implement an Open Architecture

Reduce integration and upgrade costs with modularity and loose coupling. DDS compliant pub/sub provides well-defined interfaces and plug-and-play interoperability between system components.

Decentralized for Ultra-High Performance, Scalability and Availability

Apps and devices automatically discover each other and talk peer-to-peer, including over reliable multicast. No message brokers or servers are required. The result:

  • Latency in the microseconds, even with many subscribers
  • Throughput of millions of messages per second
  • Non-stop availability with no single point of failure
  • Autonomous operation with no administration

New apps use the DDS API. Legacy apps can use Routing Service.

Seamlessly Share Data from the Edge to the Cloud (and Even in the Fog)

Run Over Any Transport

Communicate reliably over any network type and transport protocol, including:

  • Shared memory within an intelligent machine
  • UDP multicast on a LAN
  • TCP or TLS over the Internet
  • Non-IP radio or satellite links in the field

Efficiently Route Data

Intelligently bridge data across networks, transport protocols and security domains with RTI Routing Service, a smart software agent. It introspects message contents and only forwards subscribed data. It can also downsample and prioritize data when volume exceeds link capacity.

Deploy Analytics Anywhere

Run analytics and control apps where it makes most sense: at the edge or in the cloud. Apps don't change—they are independent of physical proximity and the underlying transport. Easily move intelligence to the edge to process more data with lower latency and greater autonomy.

Portable and Interoperable Product Suite

Connext DDS Professional

The world's leading connectivity framework compliant with the Data Distribution Service (DDS) standard. Includes a rich set of productivity-enhancing tools and adapters.

Go Pro
