100G passive optical network
Sporni, Alex ; Tomašov, Adrián (oponent) ; Horváth, Tomáš (vedoucí práce)
This diploma thesis deals with the current state of development of passive optical networks, with the main emphasis on high-speed passive optical networks of 50 Gb/s and higher. The opening part of the thesis provides a theoretical introduction to optical access networks, their division, elements of passive optical networks and the subsequent analysis of the latest standards. As part of the implementation, simulation topologies for various simulation scenarios are designed in the VPIphotonics Transmission Maker tool. The proposed simulations are properly evaluated in the next chapter. The quality of the proposed simulation topology is assessed using bit/symbol error rate and in some cases in combination with an eye diagram (quality factor). The output of the work are simulation scenarios for various configurations and modulation formats of the proposed optical networks. The output of the work is also a laboratory task, which will be used for teaching purposes.
DNS Data Analysis for Mobile Device Identification Purposes
Sporni, Alex ; Bartík, Vladimír (oponent) ; Burgetová, Ivana (vedoucí práce)
This bachelor's thesis deals with the problem of identification of mobile devices based on DNS data analysis. The thesis provides a theoretical introduction to the computer communication model. This thesis explains the importance of DNS in the terms of network communication between devices, It also presents the provided data sets, which contain real communication of mobile devices. These data sets must be with a suitable technique parsed and stored in a database to provide better data manipulation techniques in the later stages of implementation. This work further describes individual techniques of data processing. It also depicts in detail the methodologies for evaluating the relevance of TF-IDF and the application of cosine similarity to identify the mobile devices. The main output of this work is the evaluation of the achieved results.
