eProsima Safe DDS User Manual
Safe DDS is a C++ implementation of the DDS (Data Distribution Service) Specification, a protocol defined by the Object Management Group (OMG).
Focused on delivering a highly reliable and safe communication protocol for critical applications in industries such as automotive, avionics, and medical devices, the library has been meticulously designed as a restricted set of the DDS API that adheres to the requirements of the most stringent functional safety standards, including ISO 26262 ASIL D, the highest level of functional safety certification for automotive applications.
Safe DDS provides a communication protocol characterized by predictability, scalability, and efficiency while also ensuring data consistency, reliability, and fault tolerance in real-time systems. Moreover, the library is developed for high portability across various platforms, encompassing multiple RTOSes and bare metal environments. Additionally, Safe DDS is highly embeddable with a minimal and carefully controlled memory footprint.
Support for a variety of architectures, such as QNX Neutrino 7.1, Ubuntu 22.04 and FreeRTOS v10, is incorporated within Safe DDS, allowing its advantages to be employed on diverse platforms. The library’s cross-platform compatibility and adaptability render it an invaluable resource for real-time systems requiring robust and reliable communication protocols.
