Routing

It had been eighty years since the formation of the Galactic Congress. It was a stupid, egocentric name. We only had around a dozen colonies, and the span of our emprie was less than a thousand parsecs, but the name polled well and we've got "big plans" to cover more. I didn't really care too much about interstellar politics - or politics in general for that matter - but the Congress paved the way for new, necessary advances in technology.
They made a faster-than-light Internet.
It was pretty much necessary, really, what with there being dozens of lightyears between the closest of worlds. Conventional communications would have decades of lag between sent and received messages, and interplanetary relations would invariably fall into an amusing aside; a facade kept up by people trying to look good. And to a degree, that's what Galactic Congress was. For the most part, people paid more attention to their local, planetary governments. It was similar to the pre-World War III United Nations. But this is getting off-topic.
To make communications feasible, a network was set up. It was similar to the Wide Area Network setup of the first public Internet, that there were redundant connections along an ultrafast backbone of routers that connected, in turn, everything else. These routers, however, weren't connected to each other with cables. They were connected with pairs of entangled particles.
I'm not a physicist, but the gist of it is this: a pair of particles are made that reflect - instantaneously - what the other is doing - without regard to the distance between them. This means I can send packets of information out to Andromeda just as quickly as I could across the room! Or at least, I could if I had a connection to Andromeda. Each of these connections is a quantum bit (qubit) that can be read by either router. Because they change instantaneously across space, this means that the only limit on data transfer speeds is how quickly the qubits can be processed by the routers.

I think I've downloaded the entire Internet. Twice. Because I can.
