RTIPerftest Latency Measurement in Multi-Subscriber Scenarios

Hi,

I'm trying to run rtiperftest latency test with multiple subscribers. And I read the C++ source code:

Run RTI Perftest with DDS Security Plugin and Cloud Discovery Service in Kubernetes Pods

Hi,

I'm trying to run the RTI perftest application with DDS Security plugin enabled in Kubernetes pods. As multicast is not enabled by most k8s CNIs, I have to run cloud discovery service to make participants discover each other. However, I got the following error on the publisher:

Performance of Connext 5.3.1 on Beagle Black Bones (Perftest Benchmark)

Hello,

I  am running RTI Connext 5.3.1 on a cluster of Beagle Black Bone (BBB) devices for a project. To benchmark the baseline maximum throughput for different data sample sizes, we used RTI DDS perftest 2.3.2.  I had some questions about the observed performance results and I will be very grateful if you can help me in understanding the reason behind the observed results.

Content Filter Propagation across TCP WAN connection

Hi,

We have a DataWriter in one network sending data to a DataReader in another network over TCP.  We have configured the Participant QoS on both DataWriter's and DataReader's side to use nddstransporttcp transport library.

Calculating Queuing Delay for a DataReader

Hi,

I am trying to understand how I can calculate the queuing delay of messages for a DataReader's receive queue. For example, if a message entered a DataReader's receive queue at time-stamp t1 and the take() operation was called at time-stamp t2, I am interested in calculating (t2-t1).  Similarly, I would like to calculate the queuing delay for DataWriter's send queue. 

Can you please let me know if there are methods/fields exposed by the DDS API which can help me in this regard? 

Thank you,

Shweta

Reactive Stream Processing for Data-centric Publish/Subscribe

The Internet of Things (IoT) paradigm has given rise to a new class of applications wherein complex data analytics must be performed in real-time on large volumes of fast-moving, heterogeneous sensor-generated data. Such data streams are often unbounded and must be processed in a distributed and parallel manner to ensure timely processing and delivery to interested subscribers.

out of order delivery of samples

Hi,

We are getting data samples out-of-order on the subscriber side, when we use a QoS profile that is an extension of BuiltInQosLib-  Generic.StrictReliable.HighThroughput or when using a profile that is an extension of Generic.AutoTuning. (I have attached the xml QoS file we are using) 

This occurs even when batching is disabled. 

On the other hand, if we use the default QoS settings then we get samples in order. 

Can you please suggest why this behavior is occuring?
