Routers in space: Defense to launch (literally) space-based Internet

Summary: The Defense Dept. plans to put a router in space by 2009 to allow troops to access voice, data and video over IP, the BBC reports.

The Defense Dept. plans to put a router in space by 2009 to allow troops to access voice, data and video over IP, the BBC reports.

Eventually DoD's Iris project could allow satellites to send data directly between each other, instead of sending it via ground stations.

"Iris is to the future of satellite-based communications what Arpanet was to the creation of the internet in the 1960s," said Don Brown, of Intelsat General, one of the companies who will build the platform.

Iris (Internet Router Protocol in Space) has received a green light and funding from DOD and now aims to put "innovative concepts into the hands of war fighters in the field."

Of course it's not just any router; it's a "space hardened router" to be built by Cisco. Intelsat will build a geostationary satellite, IS-14, will be built by Intelsat.

"Iris extends the internet into space, integrating satellite systems and the ground infrastructure for warfighters, first responders and others who need seamless and instant communications," said Bill Shernit, CEO of Intelsat general.

And yes, after the military is up and running it will be opened up for commercial use.

"The Iris architecture allows direct IP routing over satellite, eliminating the need for routing via a ground-based teleport," said Mr Brown.

If you follow the logical extension - and Vint Cerf does - the Internet can be deployed throughout the solar system.

With IP becoming more prevalent for use in space, Nasa and internet pioneer Vint Cerf have also investigated the possibility of using internet technology across the solar system.

Although some work has been carried out on the necessary standards and protocols, no definite schedule has been announced for this interplanetary internet.

    Looks like they plan on "mirror-ing" the terresterial internet in bundles to be cached at each end of the earth to planet delay lines.
  • routers in space

    The use of IP in near space is likely to work reasonably well. However for interplanetary operation, a new suite of protocols has been developed that can be layered on top of tcp/ip or can work in parallel where necessary. RFC 4838 has recently been issued to describe these new protocols. While TCP/IP should work perfectly well in near Earth orbit, in space craft, and on the surface of other planets and moons, bridging the interplanetary distances and dealing with celestial motions (e.g. planetary rotation) has required some new architectural choices.

  • Routers in Space = Invasion of Privacy

    They can tell you whatever they want, and you are entitled to believe it. They are constantly instilling fear into people about how we need to protect ourselves against terrorists. I haven't seen that much in this country, terrorism that is. It is a fact though, that everytime the government updates something, for this or that, it deeply encroaches our right to privacy. As far as I am concerned, this is just another invasion. Some company gets rich, we get screwed, and the government gets to watch what we are doing in our own homes.
