New standard enables Ethernet for critical embedded systems

SAE International's AS-2 Embedded Computing Systems Committee is developing a new standard to establish Ethernet as a high-bandwidth network protocol for time, mission, and safety-critical systems. SAE AS6802 TTEthernet (time-triggered Ethernet) describes a set of services to meet the requirements of reliable, hard real-time data delivery in advanced integrated systems. With TTEthernet, critical control systems, audio/video and standard LAN applications can safely coexist in one Ethernet network. Initial supporters of TTEthernet standardisation project are Lockheed Martin, Bombardier, Embraer, General Dynamics, Sikorsky Aircraft, Honeywell, BAE Systems, Ultra Electronics, GE Fanuc Intelligent Platforms, TTA-Group and TTTech. First production programme that plans to use COTS components compliant with SAE AS6802 will be NASA's Orion crew exploration vehicle in the scope of the U.S. human spaceflight program. Lockheed Martin also works on several advanced integrated system programs using this technology.
