Ask authority operators to set `MaxAdvertisedBandwidth 0` in their torrcs
Currently, it seems that Tor clients don't use DA nodes for construction of circuits because all DA's bandwidth is set to 20, which is a very low value. To move unneeded client traffic out of DA nodes completely, we could have some torrc
option on client's side (which disables construction of such circuits) and on DA's side (which block client's requests to use the DA as a node in its circuits). Additionally, use of DA nodes in clients circuits may be governed by some consensus values published by DA nodes.
In general, in testing Tor network with a small number of nodes, enabling this option may be undesirable, but in the main Tor network it may help DA nodes to decrease their load. Also, this explicit solution may be more clean than the current probabilistic approach which relies on a small bandwidth value set for DA nodes.
This task was originally discussed in [comment] with teor.
