Internet on the ISS?

Here's an idea: why doesn't NASA put a network in the sky, with each
orbiter,
rover, space-borne telescope, and any other skyward-launched device
working as
a node? Why not internetwork space? In fact, why not use the existing
Internet?


The commercial internet is porous, insecure, and easy to take down. NASA
should be using whatever secure mechanisms are used by our military.

....Because Brad Guth and/or Wbua Znkfba would find a way to spread
their bull**** over it?

Which, except on (some) tactical radio networks, is essentially using
internet protocols. Just because you use internet protocols doesn't mean
that you have to be on the internet. You might also look up the SIPRNET
(Secret) and NIPRNET (Sensitive but Unclassified) nets, which are based on
router protocols to tunnel through the commercial internet.

The real problems with using internet protocols out of the box is that they
are not set up for SATCOM, much less deep space communications. TCP, for
example, starts out with small packets and short time outs to wait for
acknowledgements.

The military doesn't, by-and-large, have all that much remote control
stuff.

Well, its already there, as I noted that the comment, John goes out of his
way to ring colleagues on the IP phone when he can.

So, If they have Internet protocol phones, I'd assume they could ring
anywhere, as long as they can get out of the Intranet at Nasa, and out onto
the Internet?

Wait, am I reading this right? They're using VOIP phones on ISS? I'm
not surpised, just... surprised.

Can you imagine... crank calls to ISS? "Do you have Prince Albert in a
can?"

"...As a matter of fact, we do. ESA sent him up in one of the U-Haul
modules, and he's now docked outside on the LDEF rack. Would you like
me to patch you through to him?"

Are these for internal use exclusively (as an intercom system)?

No.

They use VOIP through the OCA. It's not a "VOIP phone" as such.
I think they're still using the configuration shown here, just
replace ISS for Shuttle:

The audio system, which does implement the intercom function, is
digital but does not use VOIP.

The last I heard, the TCP/IP capability on ISS does not allow
the crew to surf the web. The crew desires this capability,
of course, but it is thought to be too risky. Of course, they
might have changed the rules a week ago Thursday and not told
me.

....Nah, they're more afraid that they'll get caught surfing NASA
Watch, and Keith'll be crowing about it for the next year :-)
