Network design support
Zemánek, Martin ; Fojtová, Lucie (referee) ; Pelka, Tomáš (advisor)
The work is focused on support of computer networks. It contains basic information about the network elements and possibilities of their involvement. The steps are described so that all procedures were intelligible. The work contains various thoughts on various options for integration of network and end elements to be as effective as possible. Shown are various examples of design documentation, which should serve primarily as a good springboard. We can see the lists of VLANs, IP addresses, calculations of energy consumption and cooling requirements. The introductory section also presents a variety of topology and characteristics of networks and network elements. We deal with various technologies such as QoS, PoE, EteherChannel, Trunking, and more. We are also stacking switches and effective involvement of network elements. All these information was collected and on the basis of these applications have been developed, which should serve as online network documentation. The application is writing with Nette Framework, which also has support for Czech, so it is much material available, which relieved the work in an environment of PHP, MySQL, HTML and CSS. The result is a basic version that is ready to further develop and to be as user friendly as possible and ease the job of designing the network.

Computer Network Design
Pokorný, David ; Roupec,, Jan (referee) ; Ondrák, Viktor (advisor)
The thesis deals with the network infrastructure of a small construction company. The current state of the computer network is unsatisfactory and therefore the company decided for realization of the brand new network wiring system in addition to the reconstruction of the company´s residence. Aim of this thesis is to review the current conditions of the computer network and to design new, optimized model in order to assure effective and flawless usage of the company´s information technology resources. The final output of this thesis is the construction plan of company´s residence with network wiring drawn in. This plan will cope with appropriate regulations and will include the list of material used, table of cables and suggested layout of the 19” rack.

Optical Network Reconstruction Project Management
Dlapka, Jiří ; Ivo,, LUDVÍK (referee) ; Ondrák, Viktor (advisor)
The bachelor's thesis deals with the design of project management documentation for the project of construction of the optical network on Tetčická Street, Antonína Smutný to School Street, K Závorám and School Street. The technology used to build the optical network is currently state-of-the-art with sufficient bandwidth to transmit large amounts of data. The investor is the company TRIPLE SOLUTION s.r.o., which is also a supporter of this work. The thesis contains a design of construction, design of analyzes needed to create project management documentation and economic evaluation with a return on investment.

Standards for application of polymer optical fibres
Stiburek, Martin ; Tejkal, Vladimír (referee) ; Šporik, Jan (advisor)
The aim of thesis is description of polymer optical fiber (POF). In particular, focusing on their application and its associated standardization. After explaining the principle of signal transmission by polymer fibers, glass fibers are compared with the polymer fibers. The attention is then paid to the types of POF and their connectors. Another part is engaged in standards of polymer fibers, according to their area of application. Following chapter describes the application of polymer fibers in practice, especially in the automotive industry and sensor technology. Standalone chapter is dedicated to deploying POF fibers in LANs. It mentions comparasion with copper and wireless networks, summarizes the advantages and disadvantages. Chapter also provides an overview of the components used in POF - optical converter, switch with optical interfaces, optical network card, etc. In the practical part is created the design of home network for two-storey family house. The proposal was implemented by CableProject CAD software, first using copper cabling (UTP category 5e) and then using polymer fibers. Finally, both proposals are compared with each other. It has been made detailed financial analysis, compared performance of instalation and methods of cable instalallation. The practical part is also dedicated to measuring the parameters of POF networks, the impact of the attenuation loss, explores methods of joining glass and polymer fibers and is engaged in IPTV transmission simulation in real conditions.

Audio signal transmission over a standard Ethernet network
Rubínek, Tomáš ; Jaššo, Kamil (referee) ; Bayer, Robert (advisor)
The work describes digital audio networks for audio signal transmission. Describes the various types of digital networks and describes them. It deals in more detail with digital networks for audio signal transmission over a standard Ethernet network and compares their possibilities and uses. It compares several types of digital networks for audio signal transmission over a standard Ethernet network: Dante, AVB, Ravenna and AES67. It also compares these networks in terms of scalability and other possible uses. The practical part of the thesis is then focused on the configuration and settings of devices in the Dante network. There are stated examples for usage of the Dante network in model situations including examples of the concrete Dante devices connected to the network. In the last part of the thesis is described the realization of Dante network in the recording and postproduction room.

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.
