Network topologies and their monitoring
Sirotný, Miroslav ; Jeřábek, Jan (oponent) ; Polívka, Michal (vedoucí práce)
The master’s thesis deals with computer networks, which are currently the global communication infrastructure and play a very important role in today’s society. Most of us can be unaware of how often we interact with these networks. We almost constantly come into contact with them. They allow us to communicate through the Internet via services such as: email, skype, icq, facebook, etc... The work focuses on the design and implementation of a robot designed for exploration and mapping of computer network topology and protocols HTTP and ICMP. The theoretical part is dedicated to computer networks, seventh and third-layer ISO/OSI model, protocol HTTP and ICMP attacks against DNS, DoS attacks and detection systems and avoiding distortaions.

Data communication in distribution systems
Sirotný, Miroslav ; Mlýnek, Petr (oponent) ; Mrákava, Petr (vedoucí práce)
This project includes a basic overview of concepts as is communication, data communication and distributed to systems. Further focuses on the technology use for remote data collection. Part is dedicated PLC technologies, which use systems for remote data collection. The thesis is also mentioned the concept of quality of electrical energy and standard ČSN EN 50160. The main part is focused on the design, implementation and measurement of the PLC network.

Diagnostic tool for RTP sessions
Sirotný, Miroslav ; Komosný, Dan (oponent) ; Šimek, Milan (vedoucí práce)
This work was divided into two parts. In the first part are worked out protocols RTP and RTCP with theory. In this part I show to what these protocols are used. The second part is dedicated to proposal of application for the diagnosis of transmission parameters RTP / RTCP relations. Programs like Tcpdump win, Wireshrak, IP / TV Viewer and the Java programming language with development setting NetBeans 5.5.1. were used while creating the application. In this part we focused mainly at two important parameters like Jitter and Packet Loss.Functionality applications. Finally, we have verifed the function of the application on Multicast Network with running IPTV.
