VIENNA, Austria, 14 April 2009. The U.S. National Aeronautics and Space Administration (NASA) in Washington and networking expert TTTech in Vienna, Austria, are partnering to develop and Ethernet-based space networking standard for network centric space operations.

NASA and TTTech will collaborate on space network standards that will lead to an open space Ethernet standard suitable for deployment in upcoming space networks in NASA programs and space systems. TTTech has developed an aerospace Ethernetnetwork technology named TTEthernet that combines commercially available Ethernet infrastructure with TTTech's time-triggered services.

TTEthernet's focus is on mission-critical, safe and secure applications in various industries, including commercial aerospace, space and defense applications. TTEthernet's scalability also enables deployment in high-volume cross-industry applications, such as telecommunications, automotive or medical electronics, which can take advantage of the most advanced validation and verification procedures used in aerospace applications.

"We look forward to realizing the potential of TTEthernet technology development, which provides a high bandwidth avionics databus capability supporting future technology insertion over constellation's multi-decade mission," says Thomas Rathjen, program executive for Orion and Ares I-X in the constellation systems division of NASA's exploration systems mission directorate.

TTEthernet provides a set of time-triggered services implemented on top of standard IEEE802.3 Ethernet. Those services are designed to enable design of synchronous embedded computing and networking, capable of tolerating several faults.
