SAE International Standard Enabling Ethernet for Critical Embedded Systems

WARRENDALE, Pa., Oct. 15, 2009 - 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. It is expected that broader use of Ethernet will reduce costs and enhance design of open and scalable electronics architectures for space, aerospace, defense, ground vehicles and other industry applications.

SAE AS6802 Time-Triggered Ethernet (TTEthernet) describes a set of powerful 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 SAE AS6802 standardization 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 program 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.

SAE International’s AS-2 Embedded Computing Systems Committee addresses all facets of embedded computing systems – design, maintenance and in-service experience. The committee is part of SAE International’s Avionic Systems Division.

SAE International provides some of the key system architecture, design and networking standards; reports; and recommended practices for commercial and military avionics.
