Nick Mathewson transcribed 1.1K bytes: > Various questions and responses to the meeting logs [0]: 1. I'm not sure I understand the difference between USABLE_FILTERED_GUARD and CONFIRMED_GUARDS. 2. It seems like USED_GUARDS and CONFIRMED_GUARDS are being used interchangeably. I realise that Nick at some point in IRC mentions the former was renamed to the latter, but it isn't consistent and with so many variables I'm finding myself a bit confused. 3. From: > 14:14:41 <nickm> (There is also a secret novelty in how it handles bridges > and entrynodes) I don't actually see EntryNodes mentioned in the proposal? 4. How were all the parameters in §A.1 [1] chosen? Did we simulate the algorithm yet and fuzz the parameters under different network conditions like we did before? 5. For > 14:22:11 <nickm> #action try to think of ways that the "don't add to > USED_GUARDS till we use it" rule can be manipulated by an > attacker I assume the function governing membership in the set of FILTERED_GUARDS pushes old/stale/less-usable/less-good guards out of the set when new ones are found? That is, the size of FILTERED_GUARDS can't just grow indefinitely, right? 6. For "treating primariness as a continuum", do you mean that we should assign some float values to a bunch of guards we're trying all in parallel, then pick the guard that succeeded that had the highest value? I worry a bit that this would complicate the code and potentially result in many attempted connected to substantially less-suitable nodes.
