RouterOS Devices Management System
Konečný, Jakub ; Novotný, Tomáš (referee) ; Hájek, Josef (advisor)
This bachelor's thesis describes a design and an implementation of an information system for management control and remote configuration of devices running MikroTik's RouterOS system. Primary purpose of the system is managing all compatible devices at one place. Within each device you can modify its DNS and DHCP settings, create or edit static DNS records and static routes. System is written in PHP using Nette Framework and MySQL database.

Design methods for computer networks
Božek, Martin ; Stančík, Peter (referee) ; Hajný, Jan (advisor)
Bacherol‘s thesis deals with a topic of a suitable computer network design for a mid-sized infrastructure, its security and router and firewall realization. This boundary element is able to manage basic processes of network controlling between inner and outer network. There is a brief analysis of OSI model but we focused our attention on TCP/IP model more closely. Our project includes description and outlines an importance of the most common elements of the particular network type and their contribution to the security. Description of the three most frequent topologies of the infrastructure type follows. On the basis of the found information, we have chosen and analysed the most suitable topology from the security point of view. The result of the theoretical part is a network model proposal. In the practical part, some our findings are tested and implemented in a real setting. We used a technology of virtualization for the final realization and testing. Thanks to the virtualization used for realization and testing, we could configure the router and the firewall, which are boundary elements that separate the inner network from the Internet.

An Application Utilizing esmska Plugins for Sending SMS Messages via Web Gateways
Marton, Dominik ; Očenášek, Pavel (referee) ; Rychlý, Marek (advisor)
This thesis describes the design and implementation of a console application, that utilizes esmska JavaScript modules to enable sending SMS messages from inside of user scripts via web gateways without CAPTCHA security plugin, and of a web service with REST interface making this application accessible remotely. Both are primarily made with the purpose of running on network devices with OpenWrt operating system while trying to minimise memory consumption. The whole solution is written in C with the help of libcurl library, embedded JavaScript interpreter Duktape and standard C library uClibc.

Principals, switching functions and routing techniques in computer networks
Dvořák, Pavel ; Pelka, Tomáš (referee) ; Polívka, Michal (advisor)
This bachelor thesis consider main principles and function of active network components. Mainly is intent to component working on the third level of referential model ISO/OSI, router. There are described its main parts and more closely charactered routing protocols. Then is verified the ability of dynamic routing to react to failure in the network and there is measured the reaction time of crossing to secondary route when using different routing protocols. Another part of the thesis is focused on the questions of Quality of Service (QoS) and its support in computer networks. There are explored various ways of the QoS configuration on the routers and the proper of them is chosen and applied to the test network.

Quality of Service Ensurence in Data-Networks
Mareček, Petr ; Komosný, Dan (referee) ; Koton, Jaroslav (advisor)
The thesis deals with the issue of ensuring the Quality of Service (QoS) in data networks. The first part is theoretical, where is described QoS technology and her mechanisms. At the end of the theoretical part, possible queuing systems are shortly presented. The second part of the thesis deals with the design and implementation of a laboratory exercise with the aim of proving theoretical knowledge and evaluating the suitability of a certain queuing system according to the provided services.

Proposal of the secure network model
Kis, Matej ; Rosenberg, Martin (referee) ; Babnič, Patrik (advisor)
The goal of this work was to create a design of a secured network infrastructure with decribing different ways of securing at ISO/OSI layers. Create a list of protocols which can be used to achieve a secured network design. In the theoretical part of this work the attention was placed to analyze possible solutions, which can be appllied in a practical part of the work. The practical part involves a design of a network topology and simulation. The part of the simulation was device configuration and network security testing.

Impact of Communication Parameters on Energy Consumption of Zigbee Devices
Popelka, Jan ; Červenka, Vladimír (referee) ; Šimek, Milan (advisor)
This thesis deals with the energy research and design a simple wireless sensor networks. The data modules with ZigBee wireless communication technology. The main feature of wireless sensor networks is the minimal energy devices at low cost and maximum data reliability. Furthermore, the work describes firmware for communicating nodes with the ability to change parameters of data transmission and thus affect the energy consumption node. Calculations of energy consumption, compared with measured results and discharge characteristics of the battery packs are included in the final chapters of this work.

Design of CISCO network analysis by VePAL TX300 Analyzer
Ťápal, Tomáš ; Vychodil, Petr (referee) ; Škorpil, Vladislav (advisor)
This bachelor´s work consists of describing the network Cisco, possibilities of network analysis with analyzer VePAL TX300 and Sunset MTT, creation of manual for the analyzer VePAL TX300 and draft three laboratory exercises. The first exercise analyzes transmission parameters of the network Cisco. The second exercise compares parameters of two different types of routers. The third exercise analysis VoIP and IPTV services, especially qualitative parameters.
