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.

Advanced OS Deployment in School Environment
Fogl, Jiří ; Bidlo, Michal (referee) ; Kašpárek, Tomáš (advisor)
Computers are becoming common part of education even in first years of elementary schools. Every computer requires software installation and regular updates. With increasing number of computers this would mean unacceptable growth of repeating of the same tasks. This work describes software deployment automation and its goal is to create environment allowing such automation for elementary schools.

Rule-Driven Protocol Analyzer
Jurnečka, Peter ; Zbořil, František (referee) ; Hanáček, Petr (advisor)
The master Thesis deals with an overview of issues necessary for design of custom network analyzer. Describes the existing solutions, provides the theoretical background needed for design of custom analyzer and describes the structure of implemented system. A separate part of the work is devoted to the specification of Metamodel used to modeling of communication protocols and compiler of models modeled with the Metamodel.

Dynamic State of OMNeT++ Model via SNMP
Smejkal, Jakub ; Grégr, Matěj (referee) ; Veselý, Vladimír (advisor)
This work outlines ways of getting dynamic state into OMNeT++ model. SNMP as major technology was selected for reaching the goals. Protocols CDP and LLDP are participating in topology detection and in theoretical layer Breadth- first search is used. The output of this tool is file syntactically specied by NED language which is describing computer network.

Modelling of L2 Loop-Preventing Protocols
Hrnčiřík, Matej ; Grégr, Matěj (referee) ; Veselý, Vladimír (advisor)
This thesis informs about currently used technologies, which provide loop protection on data link layer of computer networks. It clarifies issues of Ethernet networks. Chosen protocols are then closely described. There are presented advantages and disadvantages of chosen protocols and they are compared to other technologies. Practical section describes the initial implementation of IS-IS in OMNeT++ environment, which serves as the basic building block of TRILL protocol. An important issue is to verify correctness of implementation.

Network Anomaly Detection
Pšorn, Daniel ; Puš, Viktor (referee) ; Kořenek, Jan (advisor)
This master thesis deals with detecting anomalies methods in network traffic. First of all this thesis analyzes the basic concepts of anomaly detection and already using technology. Next, there are also described in more detail three methods for anomalies search and some types of anomalies. In the second part of this thesis there is described implementation of all three methods and there are presented the results of experimentation using real data.

Modelling IS-IS and TRILL
Marek, Marcel ; Grégr, Matěj (referee) ; Veselý, Vladimír (advisor)
In this thesis, we describe the principles of IS-IS routing protocol. We introduce the current state of implementation of this protocol within the simulation framework OMNeT++. We present the implementation of the IS-IS protocol created within the ANSA project. Moreover, we employ its variant called TRILL that is nowadays deployed as replacement of STP in data-center environment. The aim is to enable the modelling of the protocols without the need having to build physical architecture.

GEO Information System for Passportization and Visualization of Wide Computer Networks
Fibich, Ondřej ; Burget, Radek (referee) ; Kolář, Dušan (advisor)
The thesis is focused on the problem of the passportization and the visualization of wide computer networks with the usage of geographic information systems. It discusses principals and properties of geographic information systems and spatial databases that are frequently used as data carriers for geographic information systems. The main part of the thesis is dedicated to the passportization of computer networks with focusing on the physical network structure. After the definition of the passport format the thesis continues with the analysis, the proposal, the implementation and the testing of the geographic information system for managing and visualization of the passport in this format. The thesis is ended by a case study that demonstrates the passportization process of an access computer network in the implemented system.
