- o Major features (traffic analysis)
- - Relays and clients will now send a padding cell on idle OR
- connections every 1.5 to 9.5 seconds (tunable via consensus
- parameters). 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.
