[p2pi] Real life torrent statistics

["Stas Khirman" <[e-mail]>]

To estimate a feasibility of ALTO/P4P for real life torrents , I collected
<ip,port> information for peers from one of the most popular "PirateBay"
torrents ( almost 20k peers) and maped their IPs to corresponded ASs. Please
find attached my working notes with some interesting statistics.

 

In short - for such kind of swarm (20k peers), almost half of peers belong
to ASs with 100 or more peers, almost 2/3 of peers belong to ASs with 50 or
more peers. Less then 15% of peers belong to ASs with 10 or less
"neighbors".

 

US broadband ISPs (Road Runner, Comcast, AT&T) have about 2-3% of total
peers each.

 

Also, I find it surprising geo distribution of the peers - majority were in
UK , not in US (probably because content is available in US theaters).
Places 3-5 taken by Sweden, Poland and Canada (in total - more peers then in
US).

 

Certainly, observed "heavy" neighboring of peers is a function of swarm
size. I intend to investigate a few medium/small size swarms to have a
multi-point picture for any future discussions.

 

I would appreciate comments, corrections and additional ideas on data
collection and analysis.
