[tor-relays] Bandwidth Measurement

Hey everyone,

as far as I know, the DAs running the bwauth scripts conduct hourly bandwidth measurements. Depending on the advertised bandwidth of the relay node, a smaller/bigger file gets transmitted on a custom 2-hop-circuit and the transmission time determines the actual bandwidth.

Now, here is my problem: Assuming that my relay node advertised 50MB/s, and is currently at 98% load (49 MB/s). To conduct the measurement, the bwauth script will send a 8MB file over my relay, but since it can only serve another 1MB/s, how will the bwauth script determine that my advertised 50MB/s is correct?
