A method is provided for performing zero-copy distribution of data samples between applications running on the same node in a system using an Object Management Group (OMG) Data Distribution Service (DDS) and/or a Real-Time Publish Subscribe (RTPS) protocol. Further provided is a method for selecting the network representation to communicate with a DataReader in a system using an Object Management Group (OMG) Real-Time Publish Subscribe (RTPS) protocol. Still further provided is the combination of these two methods to communicate transparently using zero-copy within the same node and not using zero-copy for different nodes. Embodiments of this invention lead to a relatively small communication latency that is constant and independent of the data size for applications running within a single node.

Publisher-side content based filtering methods and systems are provided to select which subscribers shall receive each data-message sent by a publisher using an Object Management Group (OMG) Real-Time Publish-Subscribe (RTPS) protocol. Methods and systems are provided for writer-side content based filtering and data distribution from a publisher to a plurality of subscribers using an Object Management Group (OMG) Real-Time Publish-Subscribe (RTPS) protocol. Methods and systems are provided for performing scalable content-based filtering and distribution from a publisher to a plurality of subscribers using the Object Management Group (OMG) Real-Time Publish-Subscribe (RTPS) protocol.
