In general, this is an open research area. But there are no good or even adequate designs out there currently that are also practical to deploy.

Why doesn't tor send random

Why doesn't tor send random data all the time to random nodes to make the connections be less correlative? They see a 200kbps burst on your tor node, and five seconds later see a 200kbps burst coming from the exit node. So why not send a baseline amount of data all of the time, and when real data needs to exit, then back off of sending the fake data by the same amount?

If you are really stuck ,you could download a copy of the Tails OS
from https://tails.boum.org/ and boot from a live cd

No, variants of the attack can work fine without javascript. (I'm not sure about the attack presented in this paper in particular, but it's a moot question.)

I will see your graph and raise you one:
https://metrics.torproject.org/bandwidth.html?graph=bandwidth&start=2010-08-28&end=2014-11-26

So yes, bandwidth is getting cheaper, but also the number of users and load on the network will grow to fill whatever the Tor network has to offer.

Also, you should do the math on millions of users all using their full bandwidth all the time -- it adds up to look very grim indeed. :( Perhaps what we need are approximations (sometimes known by the phrase 'traffic shaping') that get some of the benefits with only some of the costs?

It seems to me that as the set of relays and flows scales up, the concept of an algorithm with an exactly zero false positive rate gets harder and harder.

I mean, feel free to not discuss it, but I think our adversaries do a lot of their discussions in secret already, so our best bet is transparency and openness. Submit your analysis to the PETS symposium:
https://petsymposium.org/2015/
and get some experts to review it. The more we know the more prepared we are!
