Router Tested On Satellite In Space
The Cisco router launched into orbit in September onboard a satellite built by SSTL (and on a Russian rocket) has now been successfully tested in space, and there's a video describing this and putting routers in space. A neat twenty-year coincidence here: an early Surrey satellite has been operating for twenty years, and Cisco launched its fastest router on its twentieth birthday. What do the next twenty years hold for fast routers in space?
But did they fix the latency yet?
You need ping to play Quake from space!
Only sadness for the poor routers out there all alone.
The satellite with the Cisco router has been hijacked by attackers using a recently discovered Cisco vulnerability. Experts believe the intent is to launch a denial of service attack on the Cassini-Huygens probe. Upon gaining root access, the attackers patched the vulnerability and changed the passwords. A multi-million dollar space mission is planned next week to manually press the reset button on the router.
Unknown host pong.
Solution? Disconnect your LAN/WAN interfaces so the rotuer frees up enough memory to create the shell. Oh, better be local when you do this...

The articles were a bit lacking details, but a few things struck me.
It didn't say what they were routing between. In most instances, merchant satellites are just used for point to point connections, so they are just bent-pipes. I am assuming that they are routing between different spot-beams or transponders. Or maybe the router is actually a bridge?
One of the articles said that the satellite in question was a LEO. This means that it is in a non-stationary orbit, so ground terminals will have periodic outages, and also need to track the satellite. This complicates persistent connections.

You might have been first had you not pointed your default route to the orbiting router. The latency killed you.
Overrated / Underrated : Moderation
Don't tell me they use gravity or air pressure to do switching.
Doesn't it make you feel good to know that our freedoms are protected by politicans, lawyers and journalists.
Routers in space will be the first steps towards an interplanetary internet. The folks at CCSDS (Consultive Committee for Space Data Systems) have been working on an interplanetary internet specification for a while now. Some additional technical details and other information is also available. Very interesting stuff.
Didn't DirectPC already have NATs in Space? And just in case I need the funny mod as well: And didn't the Muppets have PIGs in Space?
SJW: a person who perceives an injustice, and while correcting it, commits a greater injustice.
The problem is that the data signals are only limited to the speed on light so interplanitary internet would be impossible.. A ping of 15 minutes from Earth to Mars?
With the routers in space, we can now detect when hostile alien invaders begin to use them to coordinate their attack and destruction of planet Earth!
Fortunately, the Cisco IOS vulnerabilities will remain intact to accommodate the breach of security that will save the planet Earth!
Only 2 more days to go!
These routers do not yet meet NASA's requirements for Class 1 & 2 missions (e.g. Hubble, Mars Rovers, Mars Pathfinder, Cassini, etc). Class 1 & 2 mandate (among other things) extremely high reliablity in areas of radiation tolerance, thermal and mechanical shock. The standards for these types of missions are extremely stringent and Cisco's current implementations for these routers *will* not meet the standards for NASA's Class 1 & 2 missions. But, suffice to say, it is a work in progress. Some demonstration missions for IP routers basically use Linux and a commerical off the shelf single board computer. This is definitely not adequate for long term and high reliablity/availabilty NASA missions. I know this because my job *is* to build an internet router for interplanetary/LEO missions including the proposed Lunar missions.
Please go visit those links providing in these comments about Interplanetary Internet. You are right in that the current protocols we use for terrestrial routing would be useless for interplanetary networks. That is why new protocols (based on TCP/IP) need to be developed that take into account that big latency you mentioned and other factors such as moving nodes(satellites, probes). Surely you don't suggest that data communication is impossible on a Solar Scale(Cassini? Voyager? Mars Rover?) Interplanetary internet is most certainly not impossible, although it probably wouldn't be suitable for a round of Quake.
