First Public Demo of ContextNet and CoreDX DDS

The Laboratory for Advanced Collaboration (LAC) presented and ran the first public demonstration of ContextNet's mobile communication middleware, SDDL, which uses CoreDX DDS. This demonstration was held at the 30th Brazilian Symposium for Networks and Distributed Systems.


Twin Oaks Computing's CFO MC at Rotary Club Veterans' Appreciation Breakfast

Twin Oaks Computing's CFO Asa Beck was the Master of Ceremonies at the 6th Annual Rotary Club of Denver Southeast Veterans' Appreciation Breakfast. This special breakfast honored current and fallen veterans, and included music and humorous military stories, told by veterans. Twin Oaks Computing wholeheartedly supports our troops, and would like to express immense gratitude to the men and women for their service to our country.


Learn how DDS works

Here is a valuable educational resource structured to build a strong understanding of DDS concepts. This DDS tour is unique because, rather than just reiterating the DDS Standards, it presents a clear and structured approach to grasping core DDS concepts.

Frequently Asked Question: Latency

Question: I have seen documentation and graphs that boast 70 usec latencies using CoreDX DDS. However, my own latency tests show latencies between .5 and 10 msec. I understand networking hardware and other environmental factors will affect latency results, but I should be able to do better than 10 msec, right? How do I achieve better latency numbers?

Answer: Latencies in the "microseconds" (50-200 usec) are certainly achievable with CoreDX DDS on all common platforms.

The first place to look for latency improvements is the Latency Budget QoS Policy. This important QoS policy, supported by CoreDX DDS, allows your application to balance low latency versus high throughput performance. The Latency Budget QoS Policy specifies the acceptable delay between when the publishing application writes data and when the data is made available to the reading application. Configuring a Latency Budget delay > 0 will reduce overhead and help CPU and throughput performance. However, it will increase latencies. When low latency is the most important criteria, the Latency Budget QoS policy should be configured with a delay of 0.0 seconds on the relevant DataReaders and DataWriters.

The CoreDX DDS distribution includes sample application code, including a latency test. This example latency test can be used as a benchmark in your environment, as well as a reference for writing your own latency tests.
