Hi, Matt, Juga, Nick and I discussed an alternative scaling scheme on #tor-dev during the patch party.
And make it a consensus parameter. Currently, it's about 7500. bwauths scale results so that the total measured bandwidth is approximately 7500 * (the number of relays they have measured). This scales their results so they are similar to the current torflow bwauths. (The current bwauths have total measured bandwidths between 35 million and 70 million. Using this scaling scheme, a bwauth that measured 7000 relays would have a total bandwidth of 52.5 million.) This scheme also allows a bwauth to scale and report partial results: if it has measured half the network, it scales to 25 million.
Under this alternative scheme, if the unscaled bwauths average relay weight changes, we change the consensus parameter. So we don't need to change torflow. See this pad for our notes and calculations: T |
