Interplanetary Internet Tested In Space

Anonymous Coward writes "After Vint Cerf planned the Interplanetary Internet, there's a press release saying that the Interplanetary Internet is now being tested in space, using the Bundle Protocol developed by the Delay-Tolerant Networking Research Group. There's a conference paper with details on the testing too. These guys were previously the first to test IPv6 in space. Now they've found something with even fewer users than IPv6 to play with!"

Can you hear me now?

Does VoIP work when there's no sound in space?

Cue packet-sending spacedwelling overlord jokes in 0101, 0011, 0001, ...

Re:Can you hear me now?

[William Robinson]

Yep. It works like this.

Peter: Hello.
Malcom: (After 1 hour) Hello.
Peter: (After 1 hour) Take the Nitro away from Sun.
Malcom: (After 1 hour) What?
Peter: (After 1 hour) Take the Nitro out of Sunshine U idiot.
Malcom: NO CARRIER.

It's the Internet, Jim

More importantly, can we adapt the technology for these tubes to build a space elevator?

This allows for retransmissions from inside the network rather than having to retransmit data from the source, as is the case with TCP.

No, this is not a best-effort protocol. Retransmission is required as in TCP, except in this case intermediary nodes along the route can take responsibility for retransmission of packets, whereas in TCP the source of the packet must carry out this role.

And you thought latency was bad on Earth...

It's just 20 minutes.. if you play a Hunter, none of your guildmates will notice the difference.

Hams had it in 1985

[Bruce Perens]

Radio amateurs ran a wide area IP network over 1200 baud AX.25 half-duplex links in 1985, and wide area networks without IP before then. You could literally hear your packet being relayed from point to point. The IP software of the time (KA9Q NOS, and later on Linux) could handle the delays just fine. It wasn't the 30-minute delays of planetary communications, but certainly much slower than conventional IP networks, seconds per packet and tens of seconds for packets to be forwarded and acknowledged. Linux has had the features necessary to do this way back in the Waltje (Fred Van Kempen) networking software, before Alan Cox started working on it. Waltje was a Dutch CB packet enthusiast. Sometimes people turn that stuff on and don't realize they aren't the first ones.

So those limited robotic probes can communicate of course. Not having to invent a whole new protocol and being able to re-use existing sattelites for retransmission is a big win for future missions.

Dear Blessed, I am writing you from Europa deeep ocean cause I halve heard you have Jen Rus heart and a sound mined.

I am in ployed at the Banke of Europah as Estate Officer. Recently, highlee respected microbe, Sister d-R81, passed away with kno known daughter celles. Through good fortune and rewards for acts of kindeness, she gathered many microgrammes of sulfur during her blessed lyffe time. No Body has bean forward to claim her Estate for Six (6 )months she hs passed. Her Estate will be absorbed soon , with no Benefisheeary. She would have want it to be past to Sum Body to do good acts with and it will be wasteful to abzorb.

Since your govment do not know yet of our existent, there is no risk too you. You will keep Sixty ( 6 0)per centage of sulfur that works out to 35.4 microgramms. I will collect theremainder when I have rode to yur plant on your spacecraft Galileo. My jupiter friend on Jupiter sent me that they have found this craft deliverd right to them.

Do not bee concrnd word. I will be Benevolent dict-ator. Sulfuric economy be flourashing.

Send yor contact lens numbers and sulfur banque code with which to strat transacshin now.

Sincerelty,

Re:Intergalactic Phising Expedition

[Stooshie]

Dear Emmannue^328*() 4532.4, I am cery interested in your offer. But a few clarifications are needed. First is it 6 Jovian months or 6 earth months. Secondly, I have a group of investors willing to collectively invest. As proof of your intention could you send us 0.1 micrograms of the sulfur and a photo of yourself holding a piece of paper with the phrase "1 @m @n 1d10t". Thankyou. Blessed.

Re:What's the point?

[Zarhan]

Actually, Delay-tolerant Networking has applications that go beyond just space. One prime example is acoustic networks for oceanic monitoring - http://ieeexplore.ieee.org/iel5/4302188/4302189/04302341.pdf has a nice paper about the application. Also, battlefield communications where there may be intermittent connectivity benefits from DTN.

Anyway, the reason for getting direct IP connectivity to space probes is to reduce the overhead: If you can just say wget http://www.jpl.nasa.gov/mars/opportunity/todayspic.jpg to access Oppy's camera instead of having to go through various hoops it makes everyones work easier. Combine this with dynamic and automatic routing (for example, for solar oppositions)..So yes, mostly the benefits are for scientists and engineers in space projects.
