CoreDX DDS Interoperability

CoreDX DDS provides immediate interoperability with standardized wire protocol, and has been identified as a high-performance data communications middleware component that achieved Open System goals. CoreDX DDS provides for loosely coupled applications, with dynamic discovery, platform independence, low-latency, high-throughput, message-oriented data communications that can be tailored by a robust set of Quality-of-Service attributes. On-the-wire interoperability is the final crucial component that opens up a world of publish subscribe applications.

CoreDX DDS Interoperability provides on-the-wire compatibility with other DDS implementations. CoreDX DDS applications can easily communicate with applications based on DDS from other vendors. This multi-vendor interoperability is enabled by the DDS Real-Time Publish Subscribe (RTPS) protocol. Twin Oaks Computing has demonstrated CoreDX DDS interoperability with multiple vendors.

With a small library footprint, measured in Kbutes not Mbytes, CoreDX DDS is perfectly suited to support space and resource constrained applications. Learn more here

Data Distribution Service Middleware (DDS) Turns 20!

Twin Oaks Computing is excited to announce in 2024, we celebrate 20 years of DDS innovation with the DDS community. From its first use case that enabled distributed communications for US Navy ships to the autonomous systems of today, the DDS family of standards has enabled new generations of applications to run reliably, rapidly and securely, regardless of distance or scale.

To commemorate this milestone, the DDS Foundation will be running a year-long celebration to highlight the 14 specifications in the DDS standard, along with selected real-world use cases. Kicking it off on January 18 is a webinar that starts at the beginning: A discussion with the original Principal Developer of the original Proof of Concept experiments, along with the lead developer for the Original DDS standard.

Thank you for joining us last month in Reston, VA. where we had a birthday celebration and live panel discussing the past, present, and future of DDS.

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.

Managing DataWriter caches with Transient Local Durability

The Transient Local Durability configuration provides some useful functionality, particularly with late joining DataReaders. However, care must be taken to ensure the DataWriter cache doesn't continuously increase.

The following QoS policies may be used to limit the growth of the DataWriter cache:

  1. Keep Last History QoS configuration
  2. Non-infinite Resource Limits QoS configuration
  3. Non-infinite Lifespan QoS configuration

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