OCI is happy to announce the release of OpenDDS version 2.1.  OpenDDS is an open source C++ implementation of the OMG Data Distribution Service for Real-time Systems (DDS) specification. In addition to C++, OpenDDS supports Java language bindings and includes a JMS provider implementation.  The new OpenDDS 2.1 release includes new UDP and multicast transport implementations, including support for reliable multicast. A new instrumentation and monitoring application and library are available to enable run-time monitoring of OpenDDS entities and applications.

The existing Java API for DDS, which is derived from the IDL PSM (Platform-Specific Model), limits cross-vendor portability and performance. It also fails to take advantage of libraries and facilities unique to the Java platform, such as generic types and built-in serialization support. The proposed RFP (which was later issued with document number mars/09-12-16) asks submitters to propose an improved Java API to remove those limitations.

A pure Java implementation of DDS focused on the needs of safety-critical systems.
