Directory connections and inter-relay connections + are not padded. Padding is negotiated using Tor's link protocol, + so both relays and clients must upgrade for this to take effect. + Clients may still send padding despite the relay's version by + setting ConnectionPadding 1 in torrc, and may disable padding + by setting ConnectionPadding 0 in torrc. Padding may be minimized + for mobile users with the torrc option ReducedConnectionPadding. + Implements Proposal 251 and Section 2 of Proposal 254; closes ticket + #16861. + - Relays will publish 24 hour totals of padding and non-padding cell + counts to their extra-info descriptors, unless PaddingStatistics 0 + is set in torrc. These 24 hour totals are also rounded to multiples + of 10000. |
