Abstract:

A new program for BitTorrent network detector is designed. The detector adopts a similar crawler technique to measure and explore the actual networks, solving the problems that the logs of tracker servers are hard to acquire in related works. The measurement data discovers an interesting phenomenon that even in a small network area, there are more than one peer downloading the file. It also finds out the time distribution character of the number of peers, the distribution of peers’ geographical locations and the rank about different types of BitTorrent client. All of the mentioned above provide data support and basis for peer-to-peer networks.

Key words: peer-to-peer network, network measurement, network traffic, location awareness, network protocol
