Yes, far more papers than implementations.
Papers are a legitmate validation route before investing in implementation. Though when faced with many rough equivalents, moving to code is the ballsy right move.
Once you have something that works well enough, or that people are at least so convinced, new ideas don't attract much interest. But maybe that's changing now.
We know fossil fuel is unsustainable at current rates.
Why did Tor go with circuit switching?
You'd have to ask Paul and the historical anonbib on that.
Was it mostly about efficiency?
Perhaps. And or prevalance of TCP / parts of historical thinking telecom models.
Also, is it easier to bury packet switching in chaff?
Which is more programmable and pluggable? Which is harder to emulate with the other? Circuit switching, packet switching, packet switching with MPLS. Why doesn't Ma Bell have 1:1 hardlines from NYC to Delhi? And does it matter to you?
Which ones, in particular?
Pick any of them and folks will say some parts are really cool and effective, other parts not so much.
But it's still obvious that you're up to something.
It seems very hard to hide that fact. But so long as free speech and or via crypto is upheld, actual fact of usage doesn't seem that bad. If not held, you've probably got bigger problems to where Libtech has to sneak in and Arab Spring your ass out.
And once they tweak your traffic, they can look at what other nodes start behaving differently.
Not if those other nodes refuse to talk with or pass traffic for you until your traffic falls back in line with expected network params. Think of it this way... TCP is nice because it silently and flexibly adapts to network conditions. When your adversary *is* the network condition, you may not want that feature. Tor checks for invalid packets via the OS stack, cell format and crypto. But it and others have zero visibility into me shaping your throughput into nice waveforms and watching whatever else your NIC does appear straight out the other side somewhere. That's dumb as fuck.
So I come back to the need for covert channels.
These are definitely useful. SDR, guerilla community meshnets, sat transponders, tropo, bulk sneakernets.
We have a very different Internet now.
What do the spies say? Does it matter?
