Weather Station with Ethernet Interface
Novák, Pavel ; Šimek, Václav (referee) ; Bartoš, Pavel (advisor)
This thesis deals with the design and construction of the meteorological station. The meteorological station is designed and constructed to be able to measure the basic meteorological parameters (temperature, humidity, air pressure) and the other three variables (measuring rainfall, wind speed, wind direction). This thesis will introduce you to meteorology. Meteorology determines the daily weather forecast and the results are used for examples in aviation or maritime affairs. The method of atmospheric origin is given in the theoretical part. Meteorology must use measuring instruments to determine quantities. The dissertation also includes analysis of the measuring instruments. The meteorological station uses the Ethernet technology. In the chapter devoted to Ethernet are described its principles, types and method of power supply over Ethernet. The following section describes the design of the entire meteorological station, selection of all components and description of their connection. The chapter about implementation contains a description of the parts which forms program part of the meteorological station. The aim of the thesis is a summary of the achieved results including price comparison of the renovated meteorological station with other meteorological stations, which can be normally bought.

Switch optimization in converged network
Švec, Adam ; Sobek, Jiří (referee) ; Škorpil, Vladislav (advisor)
Switch Optimization in a Converged Network thesis discusses the role of the Ethernet switch in the network. It describes differences between the switch and the hub in the network and the impacts on the collision domain size. In the converged network, priority data switching according to their origin and thus the qualitative point of view is also addressed - e-mails, voice services and multimedia will each behave differently. A real element, switch L3 - a switch with services quality support - is mentioned. The tool Matlab - Simulink is briefly described and a functional simplified model of the ethernet switch was created. Furthermore, the topic was used as a theme for a laboratory task in the subject Services of Telecommunication Networks. A model for Simulink and an example of the laboratory protocol for the created task are attached to the thesis.

Design of Switch Used in Modern Communication Networks
Mojžiš, Ľubomír ; Novotný, Bohumil (referee) ; Škorpil, Vladislav (advisor)
This diploma thesis deals with switching components of modern communication networks. A switch architecture focused on the quality of service is described in this paper and there are two switch models designed and simulated in the simulating program MATLAB-SIMULINK. The first model is based on classic switching and the other one is controlled by neural network. A laboratory exercise suitable for communication networks education is created in this paper on the basis of designed models.

Safety risks of current routers
Bubelíny, Peter ; Vymazal, Michal (referee) ; Vychodil, Petr (advisor)
The thesis aims to study and document the problem router security. It present the characteristic information about a router, functions, types and locations in a computer network. Because router is integrated part of network, next are described the most commonly types of attacks and generally available security technologies. The thesis also offers insight into the router as a safety device in the role of the throat network, part of the deeper security infrastructure or access point in wireless networks. Next are described the selected security technologies against some of already mentioned attacks and also are offered opportunities to improve safety router. The next are demonstrated DoS and brute-force attacks on router in ethernet network and attacks based on sniffing packets on router in wireless network. Finally, the results are presented.

Anonymization of PCAP Files
Navrátil, Petr ; Hynek, Jiří (referee) ; Holkovič, Martin (advisor)
This diploma thesis deals with the design and implementation of an application suitable for the anonymization of PCAP files. The thesis presents TCP/IP model and for each layer highlights attributes that can be used to identify real people or organizations. Some of the anonymization methods suitable to modify highlighted attributes and sensitive data are described. The implemented application uses TShark tool to parse byte data of PCAP format to JSON format that is used in the application. TShark supports lots of network protocols which allows the application to anonymize various attributes. Anonymization process is controlled by anonymization politics that can be customized by adding new attributes or anonymization methods.

Penetration testing of ANC
Dušek, Jakub ; Jakub,, Přibyl (referee) ; Sedlák, Petr (advisor)
This diploma thesis deals with the evaluation of a security solution that was recently deployed by a British company renting office space. This validation system is based on a database of MAC addresses, a database of clients and active filtering of connected devices. The first part explains the concepts of computer network, VLAN and basic concepts needed to understand the function of dynamic assignment of VLAN and IP addresses. The second part is devoted to measurements based on hypotheses, according to which measures are proposed in the last part to solve these security problems.

Intelligent lightning system
Harman, Ján ; Šír, Michal (referee) ; Bradáč, Zdeněk (advisor)
The aim of my master’s thesis is a system for control of the light intensity. It is electronic equipment which controls the intensity of the light circuits based on settings and input signals. This equipment could work on single-phase systems or multiphase systems. The equipment is controlled by the signal DMX-512 which is a standard for the control of lighting technologies. The set up of this equipment is based on a personal computer or in a limited form by a small connected display.
