NASA Taking Ethernet Into Deeper Space
coondoggie writes "While Ethernet technology has gone places no one would have envisioned 36 years ago, NASA today signed an agreement with a German Ethernet vendor to build highly fault-tolerant networks for space-based applications.
TTTech builds a set of time-triggered services called TTEthernet that is implemented on top of standard IEEE802.3 Ethernet. Its technology is designed to enable design of synchronous, highly dependable embedded computing and networking, capable of tolerating multiple faults, the company said."
At those distances, I'd have gone wireless. Wait to string ethernet to the space station until we're done with the space elevator.
He's getting rather old, but he's a good mouse.
Networking on board spaceships is bad. The Cylons can tap into them.
Would that be Aethernet?

I don't know, but it works for me.
It might be an interesting project indeed to send out a bunch of peers out into the solar system to relay sensor and communications data. A WRWAN (Wireless Really Wide Area Network) might be the kind of utility that could facilitate more reliable data flow for future exploration projects.
If you take down the sun, the entire network would fall apart in 8 minutes flat.
...but for those who go through life at impulse power, I suppose this will do.

Space memes...
Only 2000m total. Would be an interesting launch to watch though when the cable runs out.
LAAAAG!
The next Cmdr Taco duplicate will be ready soon, but subscribers can beat the rush and see it early!
because when we build a lunar colony or send explorers to mars, they will need porn too.
These are ROCKET-SCIENTISTS! They are not going to do something as silly as measure the cable in yards and the distance in meters. Rocket-scientists don't do that.
MMO Quests are like orgasms:
You may solo them, I prefer them in a group.
They already have Fault tolerant ethernet used in avionics systems called AFDX - why pay a foreign company to design an entirely new version of something we already have?
. . . and during those long, boring missions the astronauts can amuse themselves by untangling all those cables.
Which would make a good high school space project: do USB cables tangle up in space, while under weightless conditions?
If so, I'll take one look at the situation under my desk, and move into outer space.
Plus, USB is cheap; companies give away hubs and memory sticks as advertising. NASA could keep costs down by scrounging USB gear.
Schroedinger's Brexit: The UK is both in and out of the EU at the same time!
Actually TTTech is an Austrian company (founded in Vienna), there are no kangaroos here but a lot of mountains and we speak German. However great world leader Barack Obama recently suggested us to have our own Austrian language: http://www.youtube.com/watch?v=AAmaGgBrDAs ;)
The Austrians in comparison to the Germans are like the Kiwis are to the Australians, people always get us mixed up.
Will the tubes reach that high???

Gravity isn't required only some motion of the string
'...if only "Jumping to a Conclusion" was an event in the Olympics.'
Maybe I misunderstood the news but it kind of implies that TTTech is a german company which is wrong :-)
Just set the TCP timeout to 1,586,654,255 seconds. Problem solved. Next.
My favorite phrase: You have 5 Moderator Points! Use 'em or lose 'em!
I guess they are trying to build a Communications Network like they did in Star Trek. They think that just because they have relay probes, that the time delay will go down. Sorry can't have instant Convo's or Streaming at those distances.
Space ethernet + conficker = Skynet???!?
Are YOU using the TOOL, or is the TOOL using YOU? Think about it!
This sounds a bit like taking ethernet hardware (good for costs), and layering a token ring type system on top of it. Sounds like a good way to me to guarantee real-time performance to me.
at least it's made in Germany. You know the Germans always make good stuff.
frog blast the vent core
Because, you have a lot of time to kill and the install DVD is still in the box back home. It all makes perfect sense.
When bittorrent has been outlawed on Earth. There's only one way to go ... satellite bittorrent servers in space!
If you can use fiber optic links for Ethernet, why not take it a step further and use lasers? Probably have to be a pretty powerful laser to get out of the atmosphere with a usable signal but once you get past that it could probably be done. Tricky part would be aiming the beams but you might be able to use a combination of GPS signals or something equivalent, triangulation, and trajectory prediction.
so basically they can watch porn on the space station without waiting for it to buffer...
got it.
Should I expect a shortage on CAT-5 cable?
Knowing Google's lust for data collection, the Soviet Union is still alive and well inside the psyche of Sergey Brin....
If any of you klowns ever had to implement a distributed computing system on a spacecraft using the 1553 bus you'd appreciate what a huge development this could be. However, it sounds like its coming out of the Cx program which worries me. Hopefully it's not brain-damaged and it will catch on because if I never see another 1553 bus controller or RT chip again in my life that would be just fine. BTW, Spacewire is an even bigger PITA as 1553, only faster. This could possibly replace both 1553 and Spacewire, which would be even better.
I recommend a Star topology.
is DON'T network your computers in a spaceship!
