the open source DDS implementation

OpenDDS is an open source C++ implementation of the OMG DDS standards. OpenDDS also supports Java bindings through JNI.

DDS is a suite of open standards designed to handle all the data distribution chores for you: message addressing, data marshaling and demarshaling (so subscribers can be on different platforms as publishers), delivery, flow control, retries, security, etc. Any node can be a publisher, subscriber, or both simultaneously. The DDS publish-subscribe model virtually eliminates complex network programming for distributed applications. DDS supports mechanisms that go beyond the basic publish-subscribe model.

OpenDDS uses the ACE abstraction layer to provide operating system and compiler portability. OpenDDS is based on version 1.4 of DDS specification, version 2.2 of the RTPS DDS-I Wire Protocol Specification, and version 1.1 of the DDS Security specification
