OpenDDS is an open-source C++ implementation of the Object Management Group's specification "Data Distribution Service for Real-time Systems" (DDS), as well as some other related specifications. These standards define a set of interfaces and protocols for developing distributed applications based on the publish-subscribe and distributed cache models. Although OpenDDS is itself developed in C++, Java and JMS bindings are provided so that Java applications can use OpenDDS. OpenDDS also includes support for the DDS Security and XTypes specifications.
OpenDDS is built on the ACE abstraction layer to provide platform portability. OpenDDS also leverages capabilities of TAO, such as its IDL compiler and as the basis of the OpenDDS DCPS Information Repository (DCPSInfoRepo).
The primary development of OpenDDS was done by
Object Computing, Incorporated in
St. Louis and Phoenix. It is released under generous license
terms similar to ACE, TAO and MPC. See the LICENSE file for
details.

This release of OpenDDS is based on the DDS Specification formal/2015-04-10 (version 1.4). It features the following transport protocols:
- TCP/IP
- UDP/IP
- IP multicast
- RTPS over UDP/IP (unicast and multicast)
RTPS (Interoperability) features are based on the DDS-RTPS Specification formal/2019-04-03 (version 2.3). See the OpenDDS Developer's Guide and the file docs/design/RTPS for more details on RTPS.
See the Developer's Guide for information on OpenDDS compliance with the DDS specification. If you would like to contribute a feature or sponsor the developers to add a feature please see the Support section above for contact information.
For a complete detailed list of dependencies, see
docs/dependencies.md.
OpenDDS requires TAO for both IDL compilation as well as interaction with the
DCPSInfoRepo. ACE is also required, but it is always included with TAO. If you
will be using the configure script for OpenDDS (see the
INSTALL.md file for details), you do not need to download TAO
first -- the configure script will download it for you.
There are two distributions of ACE/TAO that can be used with OpenDDS:
- OCI ACE/TAO 2.2a patch 19 or later
- This will be automatically downloaded by default when using the configure script.
- Can be manually downloaded from:
- DOC Group ACE 6.5.12 / TAO 2.5.12 or later in the ACE 6.x / TAO 2.x series
- When using the configure script, DOC Group ACE/TAO can be downloaded using
one of these arguments:
--doc-groupfor the latest release--ace-github-latestto use the master branch of ACE/TAO as is. This also downloads the master branch of MPC as is.
- Can be manually downloaded from:
- When using the configure script, DOC Group ACE/TAO can be downloaded using
one of these arguments:
The TAO Developer's Guide book can be requested for free from https://objectcomputing.com/products/tao/tao-developers-guide
Perl is used for the configure script, running the automated tests and examples included in this source tree, and generating Makefiles or Visual Studio project files.
On Windows we recommend the use of Straweberry Perl.
- Google Test, for various tests.
- Google Test is required for OpenDDS tests. If tests are not built, Google Test is not needed.
- CMake, for building Google Test and the OpenDDS CMake module.
- Java, for Java bindings.
- Qt, for Monitor application and ishapes demo.
- Wireshark, for the OpenDDS DCPS Wireshark dissector.
- RapidJSON, for optional dissector sample dissection support and JSON typesupport.
- Xerces-C++, for XML QoS and DDS Security.
- OpenSSL, for DDS Security.
