eProsima Fast DDS
eprosima Fast DDS (formerly Fast RTPS) is a C++ implementation of the DDS (Data Distribution Service) standard of the OMG (Object Management Group). eProsima Fast DDS implements the RTPS (Real Time Publish Subscribe) protocol, which provides publisher-subscriber communications over unreliable transports such as UDP, as defined and maintained by the Object Management Group (OMG) consortium. RTPS is also the wire interoperability protocol defined for the Data Distribution Service (DDS) standard. eProsima Fast DDS expose an API to access directly the RTPS protocol, giving the user full access to the protocol internals.
Some of the main features of this library are:
- Configurable best-effort and reliable publish-subscribe communication policies for real-time applications.
- Plug and play connectivity so that any new applications are automatically discovered by any other members of the network.
- Modularity and scalability to allow continuous growth with complex and simple devices in the network.
- Configurable network behavior and interchangeable transport layer: Choose the best protocol and system input/output channel combination for each deployment.
- Two API Layers: a high-level Publisher-Subscriber one focused on usability (DDS) and a lower-level Writer-Reader one that provides finer access to the inner workings of the RTPS protocol.
eProsima Fast DDS has been adopted by multiple organizations in many sectors including these important cases:
- Robotics: ROS (Robotic Operating System) as their default middleware for ROS2.
- EU R&D: FIWARE Incubated GE.

You can get either a binary distribution of eprosima Fast DDS or compile the library yourself from source.
Installation from binaries
The latest, up to date binary release of eprosima Fast DDS can be obtained from the company website.
Installation from Source
Asio and TinyXML2 libraries
On Linux, you can install these libraries using the package manager of your Linux distribution. For example, on Ubuntu you can install them by using its package manager with the next command.
sudo apt install libasio-dev libtinyxml2-dev
Once these packages are downloaded, open an administrative shell and execute the following command:
choco install -y -s <PATH\TO\DOWNLOADS\> asio tinyxml2
<PATH\TO\DOWNLOADS> with the folder you downloaded the packages to.
colcon is a command line tool to build sets of software packages. This section explains to use it to compile easily Fast-RTPS and its dependencies. First install ROS2 development tools (colcon and vcstool):
pip install -U colcon-common-extensions vcstool
Download the repos file that will be used to download Fast RTPS and its dependencies:
$ mkdir fastdds_ws $ cd fastdds_ws $ wget https://raw.githubusercontent.com/eProsima/Fast-DDS/master/fastrtps.repos $ mkdir src $ vcs import src < fastrtps.repos
Finally, use colcon to compile all software:
$ colcon build
Before compiling manually Fast DDS you need to clone the following dependencies and compile them using CMake.
$ git clone https://github.com/eProsima/Fast-CDR.git $ mkdir Fast-CDR/build && cd Fast-CDR/build $ cmake .. $ cmake --build . --target install
$ git clone https://github.com/eProsima/foonathan_memory_vendor.git $ cd foonathan_memory_vendor $ mkdir build && cd build $ cmake .. $ cmake --build . --target install
Once all dependencies are installed, you will be able to compile and install Fast DDS.
$ git clone https://github.com/eProsima/Fast-DDS.git $ mkdir Fast-DDS/build && cd Fast-DDS/build $ cmake .. $ cmake --build . --target install
You can access the documentation online, which is hosted on Read the Docs.
For those who want to try a quick demonstration of Fast-DDS libraries on Ubuntu, here is a way to launch an example application.
First, download and install docker application. Open a terminal and type the following command
$ sudo apt-get install docker.io
Then, download the docker image file from https://eprosima.com/index.php/downloads-all
Load the image and run it:
$ docker load -i ubuntu-fast-rtps.tar $ docker run -it ubuntu-fast-rtps
You can run as many images as you want and check the communication between them.
