OpenDDS Essentials

OpenDDS Essentials: QoS, Keys and Instances, and Built-in Topics

Extend your OpenDDS programming skills and learn how DDS publish/subscribe offers far more than simple topic-based data transfer. Quality of service (QoS) policies, keys and instances, and built-in topics give application developers tools to build scalable and robust distributed systems.


Proficiency with middleware technologies like DDS has become an in-demand skill as more companies implement solutions driven by robotics, smart systems, and automation.

This 6-hour course builds on our Introduction to OpenDDS Programming course. Through a combination of lectures and hands-on lab exercises, participants learn how to use features of OpenDDS technology that were not covered in the introduction.

This course prepares participants to:

  • Determine which QoS policies to apply when

  • Use keys and instances to customize how data is handed by the middleware

  • Gain visibility into the discovery process and domain metadata through built-in topics 


To get the most out of this course, we recommend students have completed Introduction to OpenDDS Programming (either C++ or Java) or have equivalent experience with either the OpenDDS project or another DDS implementation.

Intended Audience

Although everyone is welcome, this course is most valuable to distributed application developers and architects looking for a standards-based, open source, publish-subscribe middleware solution.


The following topics are covered in this course:

  • Quality of service (QoS)
    • General mechanisms
    • Liveliness
    • Deadline
    • Time-based filter
    • Lifespan
    • Partition
    • Reliability
    • History
    • Resource limits
    • Durability
  • Keys and instances
  • Built-in topics

This is a live, hands-on training course. No recording of this training event will be made available for on-demand consumption.
