The environments where CoreDX DDS is deployed are diverse, and often complex with networking challenges and limitations. While some environments are simple local area networks, others are comprised of multiple subnets, complex routes, internet connections, or very low bandwidth connections. Some contain embedded devices with limited bandwidth, or applications that must dynamically adapt to new topics or data types during system operation.

Twin Oaks Computing offers a variety of CoreDX DDS tools to maximize the performance, reliability, and scalability of DDS systems deployed into environments where standardized DDS features simply do not fit or perform well.

Twin Oaks Computing is once again conducting site visits


While we're still offering online options, Twin Oaks Computing is excited to announce we're once again offering on site trainings and visits. If you're interested in a face-to-face meeting with a Twin Oaks Computing representative, or would like to schedule an in house CoreDX DDS training, contact us here.

Recorded Webinar: Security with CoreDX DDS


If you missed last month's webinar, you can view it here: Security with CoreDX DDS - Protecting your Network from Attacks.

This presentation takes an in-depth look at Industrial Internet of Things (IIoT) applications using CoreDX DDS, an implementation of the Data Distribution Service (DDS) standardized connectivity protocol from the Object Management Group (OMG), with a focus on secure data communications, CoreDX DDS is a proven, mature protocol, with over 15 years of implementation history across military, power, automotive, and IIoT industries. CoreDX DDS Secure includes state-of-the-art technologies for end-to-end and secure data communications.

CoreDX DDS Tips & Tricks


Welcome to this month's edition of CoreDX DDS Tips & Tricks, where our engineers provide quick bits of information to help our customers.

This month is about Inconsistent Topic Status.

Most developers know about the incompatible QoS statuses (requested_incompatible_qos on DataReader and DataWriter an offered_incompatible_qos on DataWriters). These statuses alert the application of a QoS mismatch between a DataReader and DataWriter on the same topic.

The inconsistent topic status is similar, but looks at the compatibility of the data types used by a DataReader and DataWriter on the same topic. This status is associated with a Topic, and should be checked, along with incompatible QoS statuses, on the Topic associated with both the DataWriter and DataReader.

If data types are incompatible, the DataReader and DataWriter will not match, the same way a reader and writer won't match if their QoS policies are incompatible.

CoreDX DDS Tips & Tricks are intended to be useful for engineers using CoreDX DDS. If you have any questions, please contact us here.
