NASA has signed an agreement with TTTech, a German Ethernet vendor, to construct "highly fault-tolerant networks for space-based applications," according to NetworkWorld. TTTech builds a series of time-triggered products called TTEthernet that sits on top of standard IEEE802.3 Ethernet, the report said. The goal is to enable reliable, synchronous, embedded computing and networking, and be tolerant of multiple faults, according to the company.
Essentially, the goal is to be able to send critical data back and forth into space without having to worry about network congestion or dropouts. In fact, NASA already uses some of the technology in its Orion Crew Exploration Vehicle (pictured). The report said that ultimately, NASA and TTTech will collaborate on space network standards that will lead to an open
space Ethernet standard--one that's suitable for deployment with upcoming NASA programs.

Very cool! I'm actually kind of thrilled to see NASA taking steps to embrace newer technologies; so often NASA has to stick with tried and true methods and equipment, and a number of those technologies are getting kind of old. :) Good on them!

Wow! Yeah, that sounds about right. ^^ I used to know someone who worked for SAIC down at Goddard Space Flight Center and she used to go on about the old equipment and old code she had to contend with on a regular basis. Thanks for the read!
