The Data Distribution Service (DDS) for real-time systems is an Object Management Group (OMG) machine-to-machine (sometimes called middleware or connectivity framework) standard that aims to enable dependable, high-performance, interoperable, real-time, scalable data exchanges using a publish–subscribe pattern.
who can give a survey of comparing DDS and other pub/sub middleware? thanks. DDS is standard, the others (Siena, Mercury, Spread etc) are not. NDDS is an commercial implementation of DDS used by Department of Defense and others. The QoS part is also important. The question is larger than simply that one (OMG DDS) is a standard and the others ...
The Object Management Group's Data Distribution Service (DDS) provides message-oriented Publish/Subscribe (P/S) middleware standard that aims to enable scalable, real-time, dependable, high performance and interoperable data exchanges between publishers and subscribers. [7] The standard provides interfaces to C++, C++11, C, Ada, Java, and Ruby.
In 2004, the Object Management Group (OMG) was granted the right to revise the ODMG 3.0 specification as an OMG specification by the copyright holder, Morgan Kaufmann Publishers. In February 2006, the OMG announced the formation of the Object Database Technology Working Group (ODBT WG) and plans to work on the 4th generation of an object ...
In 2011 OMG formed the Cloud Standards Customer Council. [2] Founding sponsors included CA, IBM, Kaavo, Rackspace and Software AG.The CSCC is an OMG end user advocacy group dedicated to accelerating cloud's successful adoption, and drilling down into the standards, security and interoperability issues surrounding the transition to the cloud.
AMI4CCM is a separate OMG standard. CIAO also provides an implementation of the DDS4CCM standard which integrates DDS as publish-subscribe middleware into the component model. The CIAO DDS4CCM implementation supports RTI Connext DDS and OpenDDS as underlying DDS implementations. AXCIOMA is the open source successor for CIAO.
Common Data Representation (CDR) is used to represent structured or primitive data types passed as arguments or results during remote invocations on Common Object Request Broker Architecture (CORBA) distributed objects.
By adding loss detection and retransmission mechanisms, reliable multicast has been implemented on top of UDP or IP by various middleware products, e.g. those that implement the Real-Time Publish-Subscribe (RTPS) Protocol of the Object Management Group (OMG) Data Distribution Service (DDS) standard, as well as by special transport protocols ...
