LAN design in the Dept. of Telecommunications
Kučera, Filip ; Minarčík, Martin (referee) ; Kapoun, Vladimír (advisor)
This diploma thesis deals with the proposal and the maintenance of Ethernet computer networks in the Department of Telecommunication property in Brno. There is a description of communication line types used in LAN computer networks in the first parts of the work. Their advantages and disadvantages are introduced too. Further there is an existing situation of the computer network on the third and the fourth floor of the Department of Telecommunication building documented. This documentation includes a design and a list of used components. The existing computer network has some minor inadequacies that were taken into consideration in the new proposal. There is a completely elaborate documentation of the new proposed network on the third and the fourth floor that contains a detailed placement and a single component configuration including their description. This documentation should significantly contribute to more effective network maintenance in the future. The computer network maintenance does not contain only servers, printers or workstations. It's also necessary to consider network parts that are not so perceptible for common users. That means single segments of computer networks with its active devices. A web based application for the effective computer network maintenance is proposed and described in this work too. The application allows administrator to keep a well-arrange view of the single network segments. All network related information is saved into a database that can help with a solution of later occurred problems.

Analysis and Demonstration of Selected Network Attacks
Jirásek, Jakub ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
The aim of this Bachelor thesis is to describe and realize selected network attacks which are taught at the FIT, Brno University of Technology. The thesis includes demonstration exercises that can be used for teaching computer network security. First part of this work discusses theory for each attack and possible security solutions. In the second part the practical realizations (for each network attack) are described.

Experimental work with POF - Polymer optical fibers
Doležal, Ondřej ; Urban, František (referee) ; Filka, Miloslav (advisor)
In this diploma thesis, the reader is familiarized with polymer optical fiber (POF). Firstly is mentioned theoretical background of optical fibers and optical transmission. The following are the basic properties and significant parameters of POF, a more detailed description of each type POF and their essential advantages and disadvantages in comparison with established optical fibers based on glass. The next chapter describes the area of practical issues: working with fibers and fiber installation, as well as the available connectors and methods of measurement of POF. Closely are analyzed knowledge of the practice, including the utilize in the aerospace and automotive industries, as well as in industrial networks, access data networks and local area networks. The practical part includes the measurement of basic transmission and mechanical parameters, including analysis of the results. The conclusion summarizes all the findings and results of this work, including possible future developments.
