  • Zetta Auto is the industry’s most robust and predictable data-centric communication solution for software-defined vehicles, leveraging the power of Data Distribution Service (DDS), Time Sensitive Networking (TSN) and Zenoh protocol to ensure end-to-end communication properties 
  • Committed to safety and reliability, Zetta Auto addresses current in-vehicle communication pain points and establishes a solid foundation to meet the automotive industry’s evolving V2X connectivity needs  
  • Zetta Auto will be extended with ASIL-D certification for in-vehicle communication in early 2024 


Vienna, Austria, July 6, 2023 – TTTech Auto, the technology leader in automotive safety software, and ZettaScale Technology, the pioneer in pub/sub/query protocol, today announced the launch of Zetta Auto. Combining their technology strengths, the two companies are delivering a unified communication platform for the automotive industry, initially focusing on making Serviced-Oriented Architecture (SOA) communication safe, performant and predictable. Extending the scope of the collaboration, Zetta Auto is also paving the way for a much-needed unification across the cloud-to-microcontroller communication continuum.  

Unlocking the full capabilities of software-defined vehicles demands a communication solution that is interoperable with automotive frameworks, and allows software and hardware to evolve independently while being performant, predictable and safe. Zetta Auto achieves this by combining the power of Data Distribution Service (DDS), Time Sensitive Networking (TSN) and Zenoh (pub/sub/query). Through the unified integration of these protocols, Zetta Auto’s capabilities are tailored to the specific needs of the automotive industry, and deliver adaptable communication solutions for both current and future vehicle architectures. 

The cutting-edge in-vehicle communication solution, leveraging and extending ZettaScale’s open-core Cyclone DDS, empowers vehicle applications to effortlessly exchange information across a wide range of operating systems, development languages and complex processor architectures and microcontrollers. Seamless interoperability and developer-friendly flexibility are achieved while ensuring predictable quality of service, remarkable throughput and minimal latency. The result is a substantial enhancement to end-to-end vehicle performance and robust networking capabilities, ideally suited for domain-based and zonal electronic/electrical architectures currently being developed. 

Zetta Auto empowers car manufacturers to harness the benefits of TSN, facilitating real-time communication within vehicles. This critical feature plays a pivotal role in unlocking the era of software-defined vehicles, enabling seamless software integration, validation and verification through end-to-end communication properties. With the inclusion of the TSN tool suite and integration capabilities, car manufacturers can confidently achieve advanced functionality with remarkable speed and efficiency. 

Zetta Auto’s integrated solution for microcontrollers builds on Zenoh Pico, a lightweight implementation of Zenoh, to guarantee minimal CPU and memory usage, resulting in an optimized footprint. It seamlessly integrates with AUTOSAR Classic, simplifying the development process with its included toolchain, and reducing the need for software component modifications. 

“With this launch, we are bringing mature technology already proven in other industries to the automotive industry and combining it with time-sensitive networking capabilities. In this way, we can unleash the potential of DDS for development teams while keeping system integrability under control. Zetta Auto is our first step in making service-oriented architecture a reality in the automotive industry.”
