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!"

Science: Vint Cerf Preps Interplanetary Internet Protocol 177 comments
TechFiends32 writes "After years of working with NASA to bring Internet connectivity to deep space, scientists say Vint Cerf's efforts may be nearing completion. To combat the apparent challenges of extending the Internet into space (such as meteors and weighty, high-powered antennas), Cerf and others have made significant efforts, like adjusting satellite-based IP, and working on delay-tolerant networking (DTN) to address pure IP's limitations in space. According to principal engineer at The Mitre Corp., Keith Scott, 'The 2010 goal is designed to bring DTN to a sufficient level of maturity to incorporate it into designs for robotic and human lunar exploration.'"

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.

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.

Vint Cerf may have worked on the development, but the idea was covered by Vernor Vinge in 1992 ("A Fire Upon The Deep"). Yes, it was fiction, but Vinge drew on his knowledge as a computer scientist. He also betrayed himself as having more than a passing familiarity with the pitfalls and pratfalls of usenet message threads. "Hexapodia As The Key Insight" (Thanks, Jack.)

What's the point? (Score:3, Insightful)
In terms of planetary travel it's actually one of the less difficult issues on the list to get communications systems working and figure out how to use systems with heavy delays. Nobody is going to be living on Mars until we have a way to get there and we're at least ten years away from a rocket that can even launch a sufficient payload.
I'd just put this on the back burner until some of the other issues are taken care of. Even the most advanced plans for sending humans to Mars still are conceptual and no prototypes exist even.
The Internet in near space (LEO or even the moon) does not have latency beyond what current protocols can deal with.

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.

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 [ieee.org] 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 [nasa.gov] 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.
