Design of reliable enterprise networks with service quality support
Kiška, Martin ; Koutný, Martin (referee) ; Novotný, Vít (advisor)
This work deals with creating a reliable corporate network and its variety capabilities against loops and supporting QoS on link and network layer. On the basis of theoretical knowledge is designed an experimental network in the laboratory of Institute of Telecommunications composed of several computers, VoIP pohones, switches and routers. Functinonal network is then tested to failure of individual nodes and the impact on network traffic. In another part of this bachelor thesis this network is tested using different QoS support options.

Modelling and Reliability Analysis of Campus Network at the BUT
Kraus, Zdeněk ; Ryšavý, Ondřej (referee) ; Veselý, Vladimír (advisor)
This thesis informs about technologies and architecture of computer network at BUT. It describes chosen technologies and some of theirs variants. Further, it contains simulation model design of a network switch device. That is followed by the model implementation with detailed description of model parts. Then, the model is tested on a set of simulation scenarios and it is evaluated in comparison with theoretical basis and real devices. In conclusion, thesis suggests future model development and improvements.

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.

New trends in data network design
Hlavatý, Jindřich ; Zeman, Václav (referee) ; Novotný, Vít (advisor)
are used. In the theoretical part I analyse some basic network protocols and their gradual development, VLANs and Spanning Tree Protocol, MPLS protocol and other. There are described parameters for the design of new networks and the models networks and their various are used, the network with a new architecture and a software-defined network (SDN),too. The practical part deals with designed laboratory exercises for teaching students. The laboratory experiments are always divided into several tasks. They are formed even students ignorant or less familiar with the issue could configure and test it.

Application of virtual local area networks for effective and flexible data network design
Brázda, Libor ; Burda, Karel (referee) ; Novotný, Vít (advisor)
This thesis is aimed to the problems of virtual local networks. In the first chapters are explained both basic and advanced methods of designing and management of virtual LAN networks. The following chapters are dedicated to the methods of effective management VLAN networks and to the protocol Spanning Tree, preventing formation of loops in redundant networks, and their exploitation in VLANs. The practical part describes the application of the implementation of the technology of virtual local networks in experimental network, containing various types of devices. Based on this theory, a laboratory assignment has been designed for the training of the students in solving such problems. The scope of the laboratory assignment is divided into simpler partial tasks, which even a less advanced student should be able to configure and test.

Design of labs for Cisco academy courses
Oujezský, Václav ; Růčka, Lukáš (referee) ; Jeřábek, Jan (advisor)
This master's work deals with the design of laboratory exercises for Cisco Academy courses. Especially is oriented on Cisco technology. The theoretical part describes various devices used in the laboratory and the issue of functionality of these devices, such as switching, routing and solve any problems with the configurations of these elements. The practical part is directly generated designs laboratory exercises, focusing on specific examples of the problems from the configuration and network management with Cisco. An integral part of work consists of supporting the presentation of individual laboratory tasks, including configuration files, settings of the device. Create labs and verify the functionality of their configuration has been realized in the laboratory Cisco Academy Brno.

Enterprise Network Design and Simulation - Cisco Virtual Lab
Ollé, Karol ; Komosný, Dan (referee) ; Soumar, Michal (advisor)
Tématem této diplomové práce (dále jen DP) je návrh rozsáhlých podnikových sítí podle doporučení stanovených společností Cisco. Dále je realizována simulace navržené topologie prostřednictvím programů s otevřeným zdrojovým kódem a dohled nad sítí prostřednictvím programu Nagios. Úvodní část obsahuje stručné seznámení se základním rozdělením sítě do jednotlivých funkčních bloků. Druhá část se zabývá popisem jednotlivých funkčních bloků a jejich rolí v rámci celé síťové topologie. Bloky jsou dále rozděleny na jednotlivá zařízení a jsou popsány služby, které tato zařízení musí poskytovat. Třetí část DP se snaží zmapovat základní požadavky na služby, které jsou kladeny na dnešní síťové infrastruktury. Hlavní důraz je kladen na dostupnost všech nabízených služeb sítě. Jsou vyjmenovány jednotlivé protokoly druhé až třetí vrstvy OSI modelu, které zabezpečují stálou dostupnost sítě v případě selhání aktivních prvků. Čtvrtá část DP se věnuje popisu návrhu síťové topologie WAN. Pátá část obsahuje popis bezpečnostních rizik, která ohrožují dostupnost sítě, tak i popis útoků, které mají za cíl krádež identity uživatele. V šesté části DP jsou popsány programové nástroje pro zprávu sítí (Nagios, Cisco Security Device Manager) a programy, které simulují Cisco přepínače, směrovače (Dynamips & Dynagen, GNS3) a Cisco PIX firewall (PEMU). Sedmá kapitola se zabývá konkrétním návrhem rozsáhlé sítě s použitím principů, které byly zmíněny v předcházejících kapitolách. Navržená infrastruktura je dále realizována pomocí simulačních programů a tato virtuální síť dovoluje demonstrovat nastavení a chování všech popsaných protokolů a zařízení. V závěrečném shrnutí je nejdůležitější poznatek, že návrh a konfigurace rozsáhlé sítě a její realizace ve virtuálním prostředí je funkční a použitelná pro pokusné účely i pro studijní účely.

Marketing analysis of the new product launch
Lai Duc, Viet ; Tahal, Radek (advisor) ; Trinh, Thuy Duong (referee)
The thesis deals with marketing analysis of the product launching of the specific product on the Czech market. The aim is to analyze marketing environment and the process of market segmentation, targeting and positioning. Thesis should serve as a basis for creating a marketing strategy for product launching of similar products on the market. The work is divided into two parts, theoretical and practical. Theoretical section provides defined basic marketing concepts, which are applied in the practical part. Each term is applied in the practical part of this thesis. The practical part includes also a situational analysis and STP process that is handled by the methodology of expert interviews and the survey.

Redundancy in data networks
Šoun, Jan ; Pavlíček, Luboš (advisor) ; Beneš, Jiří (referee)
This thesis focuses on redundancy in data networks and on technologies which are used to achieve high availability in network infrastructure. This thesis is based on industry standards published by well-known standardization authorities. One proprietary technology which can effectively replace these standards and simplify the whole network is also presented in more detail. The theoretical part individually describes all such technologies and standards. The practical part deals with an appropriate combination of these technologies and their application in a specific product environment. This work is meant to describe the whole concept of high availability in network infrastructure and should be instrumental in understanding how these technologies are deployed in practice.
