Description

We propose that relays (and bridges) collect IPv6 consumed bandwidth
statistics.

To minimise development and testing effort, we propose re-using the existing
"bw_array" code in rephist.c.

(We might want to move this code into separate relay-only code and header files, because it is relay-specific.)

In particular, tor currently counts these bandwidth statistics:

  • read,
  • write,
  • dir_read, and
  • dir_write.

We propose adding the following bandwidth statistics:

  • ipv6_read, and
  • ipv6_write.

(The IPv4 statistics can be calculated by subtracting the IPv6 statistics
from the existing total consumed bandwidth statistics.)

We believe that collecting IPv6 consumed bandwidth statistics is about as
safe as the existing IPv4+IPv6 total consumed bandwidth statistics.

Since we've done the detailed design work on this task, I am revising the estimates up.
