Hi. I have a question regarding the potential ability to isolate datawriters and readers on a local network. I work in an environment where the pplication we develop uses 4 constant domain ids. However, all the computers in our lab are on a local network. If someone runs the application on one computer, every other computer is also getting that same DDS traffic. Is there any way to isolate each computer, besides changing the domain id, through perhaps the QoS settings?
