Interplanetary Internet Tested In Space 124

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!"

    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.

    • Funny you should mention that, but I've been writing an AX.25 convergence layer to run the DTN bundling protocol over connected mode AX.25 on Linux. It's still in testing though and seems to have some issues. Hopefully I'll get it fed upstream into the sourceforge DTN2 code-base soon. Anybody want to try it out?

    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.)

    • Excuse me if I am repeating obvious conclusions. My only gateway onto the 'Net is very expensive, and I don't get all messages.

      I agree on the Usenet references... It was eerily accurate, and very enjoyable. Also, I liked his concept of aliens, which were actually alien, rather than most sci-fi.

      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.

      • Oh, sure, the practical uses. I hear 'Delay-Tolerant Networking', and I think 'carrier pidgeon' [faqs.org].

      • Right said Fred. It has been used for quite a few sensornet applications where eventual delivery of data is essential. Another example could be for connectivity on highways. For example, an email app running over a DTN bundle layer could schedule bundles for future delivery while you were using your laptop in a car. You could then have geographically dispersed access points which provide intermittent connectivity to the Internet. Whenever you cross one of these access points the DTN protocol stack on your l

      • I attended a talk given by Vint Cerf at the local Google office (in Tempe, AZ, though it's referred to as "Google Phoenix"), and he discussed another application: text messaging between soldiers, and between soldiers and commanding officers, in battlefield conditions. The devices might not have exposure to a network all the time, so they relay messages to the next node when it becomes visible/available.

        Vint Cerf said this was already being used in the field.

  • Nothing new here. FidoNet [wikipedia.org] has been providing latency tolerant networking since the 1980s. Just ask our friends in Cuba, they're still using something similar, but thumb drives and USB key fobs means the packet size can be well over a Gigabyte. Put that in your pipe I mean 'series of tubes', and smoke it!

    Just to clear up what seems to be a common confusion, DTN is *not* IP for space. It is a new networking stack that can work *over* IP, but fundamentally uses a store and forward architecture, and can uses other physical or transport layers. It will work with minibuses driving around rural africa, and it will allow "bundles" to be eventually delivered to probes that are in the shadow of a planet. See dtnrg.org
