Simple Bandwidth Scanner (called `sbws`) is a Tor bandwidth scanner that -produces bandwidth files to be used by Directory Authorities. +generates bandwidth files to be used by Directory Authorities.
-The scanner builds two hop circuits consisting of the relay being measured and -a fast exit. Over these circuits it measures bandwidth and store the results. +The scanner measures the bandwidth of each relay in the Tor network +(except the directory authorities) by creating a two hops circuit +with the relay. It then measures the bandwidth by downloading data +from a destination Web Server and stores the measurements.
-The generator read the measurement results, scales them using torflow's -scaling method and creates the bandwidth file. +The generator read the measurements, aggregates, filters and +scales them using torflow's scaling method. +Then it generates a bandwidth list file that is read +by a directory authority to report relays’ bandwidth in its vote.
