Regarding the data distribution protocol (which is used to
move data between clients and servers) we decided, based
on our analysis of current solutions, to use the BitTorrent
protocol. Furthermore, BitTorrent was tested against other
protocols and the results showed that it was considerably
more scalable and more efficient than the other approaches
[19, 20]. Also, recent data from Ipoque, an Internet traffic
management and analysis company2, shows that, nowadays,
BitTorrent represents 27% to 55% of all the Internet traffic
(depending on geographical location).
