BjÃrn Scheuermann and Florian Tschorsch of Uni DÃsseldorf want to know
what fraction of connections are used bidirectionally. They suggested to
count read and written bytes per connection in 10-second intervals and
classify connections as "below threshold", "mostly reading", "mostly
writing", and "both reading and writing".
I implemented this new metric in branch bidistats in my public repository.
Here are the results of my test relay with a reduced report interval of 2
hours (the actual implementation reports 24 hour intervals):
conn-stats-end 2010-08-10 15:55:05 (7200 s)
conn-bi-direct 3199,338,496,530
conn-stats-end 2010-08-10 17:55:05 (7200 s)
conn-bi-direct 7524,944,1301,1799
These numbers imply that 530+1799 of 338+496+530+944+1301+1799, or 43.1%
of all connections are used bidirectionally.
An open question is whether we should distinguish between connections to
other relays and to clients. I wonder if there's an easy way to tell the
two connection types apart.
