tl;dr
When building a circuit, measuring the RTT a single time could provide better
latency and anonymity while not affecting throughput. Multiple measurements
could be used for running real-time applications like VoIP or optimizing
throughput.
Despite the fact that the Tor network is curren
Hello!
Here goes my fourth status report on reducing the RTT of Tor circuits:
I continued to evaluate lots of RTT-data of Tor circuits and drew some
conclusions from that:
*) The RTT measurements of circuits are subject to multiple influences and
hence very diverse.
*) There is no single distr

Hello!
Here goes my third status report on reducing the RTT of Tor circuits:
First of all I am happy to have received feedback from Damian which I
integrated into the RTT-probing script[0][1]. With this script I have already
gathered a big amount of data about the RTTs of circuits which I am sti

Hi Robert, sorry about the delay. I couldn't sink the time a reply to
this thread deserved until now.

Hi ra
Hi all!
During the last weeks I have been very busy working on my GSoC project which
is about reducing the RTT of preemptively built circuits.
There is now a single script called "rttprober"[0] that depends on a
patched[1] Tor client running a certain configuration[2]. The goal is to

Hi all!
I started a little late on this years GSoC project[0] which is about reducing
the RTT of preemptively built circuits. Since begin of July I have been
working on scripts for Tor path generation and Stream-RTT probing.
For the path generation script "path_finder.py" I decided not to reimp
