rtiddsgen Bitfield Question

Hi,

I'm new to DDS and I was looking through the rtiddsgen release notes and found that bitfields are no longer supported.

I have several messages I'm interested in creating IDL files for that have a format similar to:

MIDAS Overview and Demonstration - Using SDN and OpenFlow to automatically enforce DDS QoS

The MIDdleware Assurance Substrate (MIDAS) uses software defined networking (SDN) and OpenFlow to automatically enforce timing and other non-functional properties for DDS-based publish/subscribe systems.

The video demonstrates how MIDAS can be used to maintain the network Qos necessary to close a real-time control loop even in the presence of network interference and a Denial of Service (DoS) attack.

regarding Connext DDS and Connext secure

Hello ,

         1.Considering DDS being a brokerless  solution, is there a meagre chance that DDS implementation can be done at broker level?

         2.Relating to the automatic discovery feature of DDS, RTI connext funadmentals of discovery somehow hampers the security aspect.

         For example , from the working context of discovery services, 

Read with query condition - .Net thread safety

I am using the C# .Net API for RTI Community DDS.

I am trying to query DDS on demand using a QueryCondition and read_w_condition() on a typed DataReader. I am trying to use the DataReader to access or take data I have previously published on demand from the application so that I can use DDS as a store of data. I am using multiple threads as I am servicing multiple interfaces.

StreamCoCo: A DSL for Processing Data-Centric Streams for Industrial IoT Edge Applications

We report our experience of developing and using a simple yet an effective flow-based programming language and its distributed execution engine for detecting behavioral anomalies in physical assets in industrial IoT systems. Our stream processing systems is built using the Reactive Extensions (Rx) library for composing asynchronous data streams and the OMG Data Distribution Service (DDS) for publish-subscribe communication over the network.
