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

With the Connext DDS data-centric approach, applications 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
