Detection of P2P Networks
Březina, Matej ; Matoušek, Petr (referee) ; Tobola, Jiří (advisor)
This document deals with design, implementation and testing of software system for detecting p2p (peer-to-peer) networks based on combination of BPF prefiltering and POSIX regular expressions packet payload matching with known p2p protocol communications. The proposed detection system includes a database with some rules of most effuse p2p protocols in format resembling to definitions for L7-filter classifier. The application is implemented in C, runs in userspace and is targeted to all POSIX compatible platforms. The combination of detector with user attached QoS controlling is complete solution for traffic reduction of common p2p protocols.

Possibilities of content distribution on the example of Czech and foreign media
Hodboď, Vojtěch ; Čermák, Miloš (advisor) ; Jirků, Jan (referee)
My bachelor thesis Possible ways to promote and distribute content on the example of the chosen Czech and foreign media describes the current state of online and print media, what problems and challenges are they facing and what are the possible solutions to those. One of these problems is also the distribution and promotion of medial content. Media are more often forced to look for new ways of finding target readers for their content which is much more complicated nowadays, in online environment particularly, because the readers' behaviour is now changing. In the theoretical part I am trying to specify and name these problems; firstly by myself and then with the help of in-depth interviews with leading representatives of few chosen Czech media. I also dedicated one chapter to the description of a start-up called Trafica, to which I am also a co-founder. My resources were on the one hand literature, such as Amusing Ourselves to Death by Neil Postman or selection of Marshall McLuhan's work, but on the other hand I have used mostly online resources, which is due to the not properly examined subject of the thesis. The practical part is focused on two surveys. The respondents of the first survey are readers. In this survey I am trying to understand mostly their reading habits. In the second research I focus...
