Measurement of data network quality parameters
Ripper, David ; Kováč, Dominik (referee) ; Zeman, Václav (advisor)
The aim of this thesis was studying and describing known methods for testing transmission parameters in data networks based on protocol stack TCP/IP. Firstly were individual transmission parameters specified and determined their impact on service quality. Another aim was to carry out a comparison of the different methodologies of measurement of transmission parameters, performed their qualifications on the basis of these findings and methodology for measuring service quality from the user's perspective was proposed. It was a web application where users measured basic transmission parameters, then the users judged videos according to the evaluation scale MOS (Mean Opinion Score) and with the help of these data was analysis, classification connection and impact of connection on MOS evaluation.

Estimation of the IP station location based on the parameters of network traffic
Ripper, David ; Komosný, Dan (referee) ; Verner, Lukáš (advisor)
This bachelor’s thesis covers the topic of evaluation of the geographical location of stations on the Internet with the help of measurements of the delay and implementation of the CBG method, which embodies both theoretical and practical parts of the bachelor’s thesis. The first part of this thesis is dedicated to passive geolocation methods, types of delays in data network, and their subsequent measurement. The second part pursues active geolocation methods, specifically the CBG method. Aim was to program a localization algorithm in the programming language PHP, subsequently evaluate accuracy of the method and compare with available methods IP geolocation.
