OpenDDS is an open-source C++ implementation of the Object Management Group's specification "Data Distribution Service for Real-time Systems". Although OpenDDS is itself developed in C++, Java and JMS bindings are provided so that Java applications can use OpenDDS -- see java/README and java/jms/README for details. OpenDDS is built on the ACE (http://www.theaceorb.com/product/aboutace.html) abstraction layer to provide platform portability. OpenDDS also leverages capabilities of TAO (http://www.theaceorb.com/), such as its IDL compiler and as the basis of the OpenDDS DCPS Information Repository (DCPSInfoRepo). The primary development of OpenDDS was done by the ACE/TAO development team at Object Computing, Incorporated (http://www.ociweb.com) in St. Louis and Phoenix. It is released under the same generous license terms as ACE, TAO and MPC. See the LICENSE file for details.

If you encounter any problems with this release please fill out the PROBLEM-REPORT-FORM file found in this directory and send to support@ociweb.com. If you desire responsive commercial support for OCI on any problems you encounter, we strongly recommend that you set up an account before you actually need help. There is no cost to establish a normal account. Support charges only apply to work actually delivered. However, we do offer premium level accounts for customers with specific support and enhancement needs, and there may be ongoing charges for such premium service. To set up a support account or to find out more about the support options available, please contact sales@ociweb.com. ====================================================================== * Features This release of OpenDDS is based on the DDS Specification formal/07-01-01 (version 1.2). 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/2014-09-01 (version 2.2). See the OpenDDS Developer's Guide and the file docs/design/RTPS for more details on RTPS. OpenDDS has been found to perform better than other similar TAO services (notification and real-time event channel) by a factor of two or three. The features offered by the RTEC and NS are similar to DDS, but not identical, so carefully examine your use-cases before choosing one service over another. Speed is not the only criterion. Currently OpenDDS does not support the Data Local Reconstruction Layer (DLRL) portion of the DDS specification. See the Developer's Guide for further information on OpenDDS compliance with the DDS specification. This document is freely available as a PDF file from the same location where OpenDDS can be downloaded. Some additional notes about compliance with the DDS specification can be found below. If you would like have OCI add a feature to OpenDDS please see the Support section for contact information. ====================================================================== * Dependencies ** TAO OpenDDS requires TAO for both IDL compilation as well as interaction with the DCPSInfoRepo. If you will be using the "configure" script for OpenDDS (see the INSTALL file for details), you do not need to download TAO first -- the "configure" script will download it for you. At a minimum, you must be at one of the following versions in order to properly compile OpenDDS: *** TAO 1.6a patch 14 *** TAO 2.0a patch 7 *** TAO 2.2a patch 5 *** TAO 2.3.1 (DOC Group) Note that the 1.6a, 2.0a, and 2.2a releases are from OCI and can be obtained from http://www.theaceorb.com/. The DOC Group releases can be obtained from http://download.dre.vanderbilt.edu/. ** GNU Make GNU Make 3.80+ was used for automating the compiling and linking of OpenDDS on Unix and Linux systems. ** Perl Perl is used for running the automated tests and examples included in this source tree, or if you will be generating Makefiles or Visual Studio project files. In most cases you will *not* need to generate Makefiles/project files for OpenDDS itself (but see the INSTALL file for details), but doing so for your own application code that uses OpenDDS is recommended. On Windows we recommend the use of ActiveState Perl. The "configure" script also uses Perl. * Build Targets * Operating Systems This release of OpenDDS has been tested under the following platforms: Linux family: ** Red Hat EL 5, x86_64 ** Red Hat EL 6.2, x86_64 ** Red Hat EL 6.3, x86_64 ** Fedora Core 6, x86 ** Fedoras 12 x86_64 ** Ubuntu 12.04 LTS, x86_64 ** openSUSE 11.4, x86_64 Windows family: ** Windows Server 2003 ** Windows 7 (64-bit) ** Windows Server 2008 R2 (64-bit) Others: ** Android NDK ** SunOS 5.10 (Solaris 10) (SPARC) ====================================================================== * Compilers This release of OpenDDS has been tested using the following compilers: ** Microsoft Visual C++ 7.1 with SP1 (Visual Studio .NET 2003) ** Microsoft Visual C++ 8 with SP1 (Visual Studio 2005) ** Microsoft Visual C++ 9 with SP1 (Visual Studio 2008) ** Microsoft Visual C++ 10 with SP1 (Visual Studio 2010) ** gcc 4.1.1 ** gcc 4.4.3 ** gcc 4.6.1 ** gcc 4.8.2 ** Clang 3.4 ** Sun C++ 5.9 SunOS_sparc Patch 124863-01 2007/07/25 OpenDDS 3.6 is planned to be the final version to support a number of older compilers. If your project requires support for any of the following compilers, you will need to either stay with OpenDDS 3.6 or contact OCI for support. ** Microsoft Visual C++ 7.1 with SP1 (Visual Studio .NET 2003) ** Microsoft Visual C++ 8 with SP1 (Visual Studio 2005) ** gcc 4.1.1 * Building and Installing For building and installation instructions see the INSTALL file in this directory. ====================================================================== * OpenDDS Compliance with the DDS Specification See http://www.opendds.org and the OpenDDS Developer's Guide at: http://download.ociweb.com/OpenDDS/OpenDDS-latest.pdf
