File exchange on the internet
Tropp, Peter ; Pelka, Tomáš (oponent) ; Polívka, Michal (vedoucí práce)
The main aim of my thesis was the TCP/IP protocol issue and the data transfer over the internet using FTP protocol. The thesis is demonstrating the main settings of a server, his functionality and it further describes the development and use of HTML and PHP protocols in my created application. The final chapter of my thesis explaining the resolution of web application interfaces for complex work with and portability in virtual environments.

Localization of IP stations based on model of probability delay measurement
Tropp, Peter ; Komosný, Dan (oponent) ; Verner, Lukáš (vedoucí práce)
The master thesis is dealing with Internet host localization methods, more exactly with determining geographical position of the unknown Internet host connected to the network using RTT delay measuring. The first part is dealing with description of RTT delays that may occur in the network and tools for their measurement. The next is part of thesis is devoted to description of two kinds of localization methods. Ones that are using existing data to determine the position of Internet host also called passive methods, and others that are using RTT delay measurement, also called active methods. The main part is focused on GeoWeight method which is based on geographical localization estimation of Internet host. It is based on RTT delay measurement using the principles of CBG method, enhanced by introduction of the theory of weights according to the probability of the target Internet host. The last part is describing the application that was made to determine the geographic localization of the target Internet host using GeoWeight method. The application was afterwards tested by measuring RTT delay in PlanetLab experimental network. At the end the final measured results were compared with other localization methods (CBG, Octant, SOI, GeoIP).
