RTI Connext and Intelligent Distributed Systems

RTI is the best in the world at connecting intelligent, distributed systems. These systems improve medical care, make our roads safer, improve energy use, and protect our freedom. Based on the Connext databus, RTI’s software allows applications to exchange data in real time and provides the non-stop availability and security essential for mission-critical systems. The Connext databus enables applications to work together as one, integrated system, significantly reducing development, integration and maintenance costs.

Connext has proven successes in thousands of safety- and mission-critical systems including autonomous vehicles, connected medical devices and next-generation defense systems.

Connext: Data-Centric Framework for Performance, Scalability, Autonomy and Reliability

With the Connext data-centric approach, applications and devices automatically discover each other and talk peer-to-peer, over reliable multicast, across platforms and large-scale and geographically distributed systems. 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 in highly distributed systems
