Model of computer network in MATLAB/SIMULINK environment
Zedníček, Petr ; Zeman, Václav (referee) ; Kolka, Zdeněk (advisor)
The bachelor thesis deals with simulation of TCP protocol behaviour in Wireless optical environment. The thesis examines the various parameters of the protocol and evaluates their response to the transmission speed. The key objectives of the thesis are the introduction to the problems of communication, specially the description of the transport layer architecture, TCP / IP and congestion management mechanism NewReno. A large part of the thesis is devoted to modelling communication points and a model of optical wireless connections. The results will be applicable to create a new communication protocol for Wireless optical environment.

Attacks on active network elements
Ščepko, Richard ; Kacálek, Jan (referee) ; Polívka, Michal (advisor)
The bachelor thesis deals with the topic of the security of computer networks. The tasks of the bachelor thesis are the attacks on active network elements with the aim of the catching of data between two users. In the created structure with a stellate topology, the user stations have connect to the active element (switch). In the thesis, the individual ways of attacks and the significance of ARP proceedings to MAC addresses have describ. Several programmes have use in order to take control over the device. Due to a big amount of these active elements the source code of the programmes had to be alter. The work with the programmes ARPtool and ARPoison demanded the operational system Linux, in our case the distribution of Ubunt. The programme WinArpAttacker could be set off under the system Windows XP as well. The achieved results and the description of the practical part are discuss in detail in the summary of the thesis. The result is the catching communication with the help of the programme WireShark.

LAN design in the Dept. of Telecommunications
Kučera, Filip ; Minarčík, Martin (referee) ; Kapoun, Vladimír (advisor)
This diploma thesis deals with the proposal and the maintenance of Ethernet computer networks in the Department of Telecommunication property in Brno. There is a description of communication line types used in LAN computer networks in the first parts of the work. Their advantages and disadvantages are introduced too. Further there is an existing situation of the computer network on the third and the fourth floor of the Department of Telecommunication building documented. This documentation includes a design and a list of used components. The existing computer network has some minor inadequacies that were taken into consideration in the new proposal. There is a completely elaborate documentation of the new proposed network on the third and the fourth floor that contains a detailed placement and a single component configuration including their description. This documentation should significantly contribute to more effective network maintenance in the future. The computer network maintenance does not contain only servers, printers or workstations. It's also necessary to consider network parts that are not so perceptible for common users. That means single segments of computer networks with its active devices. A web based application for the effective computer network maintenance is proposed and described in this work too. The application allows administrator to keep a well-arrange view of the single network segments. All network related information is saved into a database that can help with a solution of later occurred problems.

Building and using of a small computer networks
Chuchmák, Miroslav ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
This Bachelor Thesis deals with designing and building home network according to user requirements. A major aim of this thesis is to describe how to proceed, when creating a draft of home network extension. It is explained how the network can be expanded by other network elements, so that, it allows users to access the Internet and data store from home network and beyond.The Bachelor Thesis is divided into four segments. The first segment assesses the current condition of the home network, in the second segment, the new solution is suggested. The third segment describes the realization of a home network, including the configuration of a new device. The last part evaluates the new state, including the cost of implementation.

The Construction and Usage of Smaller Computer Networks
Straka, Martin ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
The main goal of this bachelor thesis is to document the gradual building of a computer network and its functioning including the theory necessary to create a step-by-step guide for doing so. The theory concerning foresaid funcionality was gained via the use of internet resources and the literature mentioned in the document itself and the practical part is based on the use of resources similar to the ones available at the workplace designed for its use. The document itself is about designing the correct network usable for a small business which is however capable of using higher tiers of client-server network functionality and the traffic monitoring available to it. The second goal is to choose and set up such network services which are crucial or auxiliary for the business core funcionality and the final part is about expanding such small network using VPN.

Building and using smaller computer networks
Ďurica, Matej ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
In these days, the widespread creation of home networks, due to the continuous development of computer technology for personal use. These networks are formed, for example, with the aim of facilitating access to information, ease of communication between people and control of various devices in the home. Their development is influenced by trends in information communication technologies in the market. This bachelor thesis is fully focused on the practical implementation of the proposal for extension of the original smaller home network using the new network elements (wireless routers, switches, network printers, NAS server, device for live monitoring of security cameras) and rendering certain network services (DLNA, print server, VPN, iTunes server, live monitoring of security cameras). A given network was tested with respect to performance network and its response, coverage of Wi-Fi signal, testing remote access, power consumption, read and writes speed of the NAS server.
