Please let us know the result.
Ok, i'm seeing it. For the bandwidth the data available is "Bandwidth Kb/s". I would like to know the historical bandwidth data that's went out of exit-traffic "given a period of time" (for example 1 month). And, said that "period of time" which was the total amount of bandwidth that got trough Tor Exit Node? Additionally, when i see "Bandwidth Kb/s" i do not see "Tor Exit Traffic" but just "Tor Traffic" that also means: - Relay - Entry (for Guard nodes) Are there Tor-Exit-Traffic-Only statistics? I would like to provide an answer to the question: "How much it would cost to monitor X% of Tor Exit Traffic for an enemy?" Where X could be 70-80-90% . Now that we have *Big Tor Exit Relay*, and almost all of them are also Guard Nodes, the questions is: Is it possible that by monitoring just 20 high bandwidth server (for example) the enemy can get 70-80-90% of Tor Exit Traffic? To be able to provide that answer we would need to have Tor Traffic Statistics only for Tor Exit Traffic, provided within a given sample period and compared with the Total Tor Traffic, given the same sample period. Anyone interested in getting in-depth with such analysis? -naif _______________________________________________ tor-talk mailing list tor-talk@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
