In the diploma thesis we tackled the analysis of the deep torrent phenomenon. We studied the Bittorrent protocol and its version from the year 2005, which operates without the presence of servers. We created a system to analyze and extract content from the traffic that is accessible on the network but cannot be found on torrent discovery websites (like Thepiratebay), which is typical for deep torrent resources. We assessed the dimensions of the deep torrent and the share of deep torrent in Bittorrent traffic. We also assessed the share of deep torrent in relation to different countries, internet service providers and autonomous systems.
