Tta-Group Consortium

TTA-Group consortium was a cross-industry community for technical and market development of safety-related architectures and time-triggered networks. TTA-Group promoted cross-industry technologies for time-triggered solutions and concentrated on the aerospace, off-highway vehicles, railway, and industrial control markets, where demanding requirements for safety-critical applications have to be fulfilled at low cost. One of the major outcomes of this cross-industry collaboration is the creation of two industry standards: Time-Triggered Ethernet (SAE AS6802): an industry standard that establishes Ethernet as a deterministic networking technology for time, safety, and mission-critical embedded systems and critical infrastructure applications.

Find out more on sae.org In addition, market leaders from the off-highway and specialized vehicle industries have joined forces in TTA-Group’s Steer-by-Wire Working Group. In this working group members combined their know-how and experiences to implement a cost-efficient steer-by-wire system. Many TTA-Group activities, particularly relating to time-triggered networks, have now been taken on by other consortia. The 802.1 task group is working towards TSN (Time-Sensitive Networking) standardization, AVnu is focused on interoperability and conformance testing, the OPC Foundation has committed to open real-time data exchange, and Industrial Internet Consortium members are implementing these technologies collaboratively. The breadth of these activities shows the importance and acceptance of deterministic networking across industries today. TTA-Group would like to thank its members and partners for a fruitful collaboration.
