Hi I am junior student in Sungkyunkwan University,South Korea I am studying Tor for my paper In my research, onion router has to report its bandwidth by sending descriptor to authority directory. and then authority directory verifies onion router's bandwidth [Question 1] I hope to know the way how authority directory verifies bandwidth which came from onion router. I was told that authority directory had bandwidth verifying tool called bandwidth scanner. How can I get source code of bandwidth scanner ? [Question 2] I made my own onion router, I configured my onion router's bandwidth 100kB/s But, In updated cached-microdesc-consensus file, My onion router's bandwidth was estimated at 20kB/s and there is "unmeasured=1" It means my onion router's bandwidth had not been estimated. what is difference between measured router and unmeasured router ? Thank you for reading my question
