NASA Tests Deep-Space Network Modeled On the Internet
hcg50a writes "NASA has successfully tested the first deep space communications network modeled on the Internet. Working as part of a NASA-wide team, engineers from NASA's Jet Propulsion Laboratory in Pasadena, CA, used software called Disruption-Tolerant Networking, or DTN, to transmit dozens of space images to and from a NASA science spacecraft located about 20 million miles from Earth. The store-and-forward protocol was designed by NASA in consultation with Vint Cerf. Here's a discussion from last July before the test began."

Look where all this talking got us, baby.

Would sub-space internet radio broadcasts be subject to a DRM?

...and route around event horizons.
This is very exciting, not only because of its utility in space, but because of its utility on Earth as well. Particularly in areas with unreliable internet service, delay-tolerant protocols can be extremely helpful for allowing basic connectivity to the outside world. Consider the choice is having no internet communications at all versus waiting a day or two for your email to travel out of your village, onto the passing truck that is caching data, and into the city where it can proceed through a reliable internet connection. DTN is powerful stuff.
It really kills me when people dismiss developments in space programs as being too far removed (no pun intended) from the rest of us to be relevant.

Space Porn!!!
We already have a working _global_ _worldwide_ _free_ network based on store-and-forward protocols.
It's called FIDONet. It's almost dead now, but it was very alive during early 90-s before the advent of cheap Internet.
Kids...
The previous technique of interplanetary messenger pigeons was obviously lobbied against by PETA as a disgusting abuse of animals.

Deep space my arse! Its just space. We've not even stepped out of our own little planet-moon system yet and we think we want to start using up space-faring superlatives. Morons! Soon the term deep-space will be about as meaningful as artificial intelligence (assuming deep-space was ever a meaningful term in the first place). If this system is for "deep-space" then what will we call a communication protocol that works well between stars?

So all the displays on the space station have in large print this message displayed:
ALL OF THESE WORLDS ARE YOURS EXCEPT EUROPA. ATTEMPT NO LANDINGS THERE.
That would be fun.
The Internet is generally stupid
So in the future, when you download pr0n, it won't be coming from China, it'll be coming from Uranus. What a worthwhile use of such advanced technology.

UUCPNet, Pathalias, and the UUCP Mapping Project.
Kids, indeed.
I still have several names registered with the UUCP Mapping Project as of their shutdown (freezing the namespace).
Some of them still exchange mail via UUCP, too. Both with each other and the rest of the net. B-)
(In fact one of those rest-of-the-net links was down for a while and came back up right after McColo was cut off. B-> )

Running mailing lists with a periodic UUCP link in the path has an additional side-effect: It limits the traffic explosion from mail loops that are not detected to a manageable volume, giving the admin time to shut down the offending address.
= = = =
I understand that UUCP mailnet is ALREADY in use in Africa in a very interesting form:
- Villages have a WiFi-enabled machine to exchange mails and files with the outside world.
- The local mail carrier has a bicycle with a WiFi-enabled, battery-powered machine with a decently large disk.
- As he cycles from village to village the bike-mounted machine associates with the local machine and UUCP does its usual magic, transferring mail, files, and download requests. (Don't know if they also run netnews groups on it...
- One of the machines on his route has internet connectivity and transfers the mail, files, and download requests to the rest of the world.
All with legacy protocols doing what they always did. And he doesn't even have to stop pedaling. B-)

I see no mention of these measures, and am not amused by this ridiculous lack of foresight if in fact they are omitted. These need to be present from the start, not attempted to tack on later.
It would be much easier for anybody to spy on backbone communications in this giant wireless system than what we currently have with wired backbones.
From /etc/services:
Still works if you've got UUCP neighbors configured.

Ever notice that you never see Al Gore and Vint Cerf in the same place.
The need for store-and-forward seems obvious to me due to the high latencies, and I thought it had always been working like this. Maybe it's hard to evolve in that area due to the long time needed to prepare each project and the risk of failure.
Actually it is already implemented in Linux for the ax.25 network stack:

I could have sword I had read about DTN as DELAY Tolerant Networking. Was that a nomenclature change, or am I just making things up?
I was waiting for someone to ask where we can find the RFC covering the new space protocol, but your comment above is the only one that even mentions the term.
So where is it? You can't have a protocol without an RFC, especially from a founding father of the Internet!

They are not omitted. RFC5050 discusses the authentication and security requirements in addition to the bundle protocol specification. However, note that it would be inefficient to implement authentication and security on every node -- it's sufficient to implement them on the boundaries of a controlled network.
Since this is designed for use over very expensive, highly controlled links (e.g. the Deep Space Network), anonymity/privacy wasn't really a high priority. However, the protocol doesn't preclude sending encrypted bundles, and AFAICT provides all the necessary infrastructure foranonymous transmission, although making that play nicely with authentication/security might be tricky.
Although I'm not a member of the IETF DTNRG, I am doing a Masters project involving DTN over ad-hoc wireless robotic networks for distributed behaviour applications.

This is just them "telling" us that they have a Stargate, and have been using it for 10 years prior to this statement.
I wonder how their Sam looks...
And the result looks like the Internet? Is this a huge surprise?

A simple google search for "uucp bicycle motorcycle wifi" brought up a number of such things.
One was the "motoman" project, which is essentially what I described but with mororcycles in Cambodia.
Here's a page in the OLPC project Wiki the motoman page on the OLPC project Wiki, which gives this and several other links to info on it.
