Current Modern Didactic Means used in Management of schools and Education
Ladrová, Iva ; Svoboda, Petr (advisor) ; Trojan, Václav (referee)
The topic of the importance of modern didactic tools in the current conditions of pedagogical practice is considered as contemporary and often discussed. The thesis deals with the question whether the application of modern technology can streamline the work of teachers, including school management and also whether it can become one of the criteria for raising the level of education and organization development. The thesis gives an insight into the ability of school management and other education participants to accept, but also induce changes and innovations in education. It also concerns the issue of schools' open-minded thinking and providing lifelong learning to local community. The thesis attempts to find a mutual relationship between effective application of modern technology, collaboration and the impact on results of entire work. The thesis deals with the use of ICT across different types of schools. The survey should also verify the impact of didactic tools on the quality and results of education by type of school, especially those who participated in the project of Ústi nad Labem Region called Community School (elementary, secondary, special), including feedback. The output of the thesis is summarization, interpretation and completion of the data obtained.

SDN Routing According to Transmitted Content
Gavryliuk, Olga ; Franková, Barbora (referee) ; Holkovič, Martin (advisor)
This works main point of focus is routing in software defined networks, which allow routing based on transfered packets. For accomplishing this task it was necessary to create a detection mechanism, that finds the connection within the OS which needs priority handling. New connections are sent via a routing aplication which is running on the SDN controller POX. The controller divides applications based on two criteria: The application requiring the largest bandwidth and the application requiring the fastest route. For this purpose four algorithms for routing data based on application preferences were designed and implemented. The applications were implemented in the Python language and they were tested in the simulation tool Mininet.

Network Access Monitoring in OnePK Enabled Networks
Kollát, Samuel ; Polčák, Libor (referee) ; Ryšavý, Ondřej (advisor)
This report contains design, architecture and implementation of a system that is used to~monitor services and files in computer networks. The monitoring system is based on~principles of software defined networks. The~first part of the report focuses on the description of~ SDN principles and OnePK platform, which is used for the construction of the monitoring system. The second part of the work consists of the design and implementation of~the~monitoring system as a OnePK application. Finally, the evaluation of the monitoring system is provided.

Secure Transport of NetFlow and IPFIX Records
Štěpánek, Adam ; Grégr, Matěj (referee) ; Podermański, Tomáš (advisor)
This bachelor thesis deals with an IP flow based data network monitoring system. It presents the architecture of the NetFlow based monitoring, explains the basic terms, the NetFlow protocol and its alternatives. Further, weak spots of the monitoring systems are determined and a conceptual solution is proposed. This solution is implemented and described in detail. Finally, testing methods and results are discussed and the possibilities of further development and optimization are proposed.

Statefull Processing of TCP/IP Flows
Olbert, Jakub ; Žádník, Martin (referee) ; Kořenek, Jan (advisor)
The fast development of computer networks brings the necessity to protect those networks against more and more advanced attacks. The security systems require an advanced analysis for their operation which is carried out based on the stateful processing of flows. This Bachelor Thesis focuses on the proposal and simulation of the stateful flow processing system. The proposed system uses a specialized hardware for network operation processing acceleration of high-speed backbone lines. The specific feature of the system is the flow memory distribution between the hardware and software. The created simulation model will make it possible to test and optimize the stateful flow processing system already in the phase of proposal and thus the possible implementation will be facilitated.

A Network Control Language for OpenFlow Networks
Antolík, Dávid ; Veselý, Vladimír (referee) ; Ryšavý, Ondřej (advisor)
The main goal of this bachelor thesis is to design and implement a high-level language for declarative configuration of Open-Flow networks. The compiler of the language, data model and interpreter were implemented employing Trema as the underlaying Open-Flow controller. The implementation was tested in a virtual network environment and it was shown that it is fully functional for basic network configurations.

Cluster Solution for HA OpenVPN
Dokoupil, Jiří ; Kašpárek, Tomáš (referee) ; Halfar, Patrik (advisor)
The aim of this bachelor's thesis is to analyze the possibilities for running the OpenVPN daemon in a cluster and to implement such a solution. At first, the thesis analyzes current technologies and possible approaches to this matter. Next there's one possible solution described more and implemented. In the end there are results being analyzed, mostly by describing the tests, that took place with the implemented solution.
