Visualizing OSPF topology
Turinský, Pavel ; Mareš, Martin (advisor) ; Forst, Libor (referee)
Network administrators need to be aware of the state of their network. While link- state routing protocols like OSPF have the required information, there was no easy way to present it to the administrator. To solve this problem, we developed Birdvisu, a program to visualise the topology as seen by the BIRD Internet Routing Daemon. Our approach allows the topology to be easily annotated with other data, providing an extensible way of analysing the topology. While not fully featured yet, Birdvisu helped discover several misconfigurations in a community-run network connecting about 1600 people. 1

Augmented-reality Multiplayer Game
Čermák, Michal ; Zavoral, Filip (advisor) ; Forst, Libor (referee)
With the advent of COVID-19, there have sprung up phone applications that track the contacts of its users. A bad accuracy of location-based proximity at close range, especially indoors, drove developers to look for other means of obtaining the device proximity. Bluetooth came as a logical pick as all phones have it. In this thesis, we have created a phone framework that uses GPS and Bluetooth to acquire accurate proximity of its players. The proximity retrieval and common server functionality have been encapsulated into a general-purpose library that is used in the implementation of a simple augmented reality game. We have conducted experiments on the game showing how Bluetooth-based and GPS-based proximity behaves. Then we have discussed when to choose one over the other. 1

Production Line Control System
Vysoký, Přemysl ; Forst, Libor (advisor) ; Holubová, Irena (referee)
Thesis describes an implementation of a corporate system designed for ma- nagement and control of an assembly line production. The system is a PHP ap- plication with MySQL database and a web user interface. System design is based on generalized demands of a real company where the software is being used. The solution includes user and user group administration, an editor and a viewer of a manufacturing manuals of the assembly line products and an assembly line production control itself. Software allows creating an assembly line and work- place schemes, defining product parameters, creating manufacturing procedures and linking products with their manufacturing manuals. The system is designed for an easy integration of new extensions and supports a large scale of screen resolutions. 1

H.323 Gatekeeper
Kratochvíl, Daniel ; Forst, Libor (advisor) ; Obdržálek, David (referee)
The purpose of this work is to design and implement a Gatekeeper service (a server for H.323 RAS protocol) with an integrated H.323 proxy. Thesis includes also a H.323 RAS protocol tester that can act both as a server and a client. The application is implemented in the C++ language using OpenH323, PWlib and readline libraries and is designed to run as a daemon on the Linux operating system. Strict usage of the platform independent libraries provides the ability to run on other operating systems. Linux and FreeBSD were successfully tested but another Unices, Windows or MacOS X should be suitable as well.

Wireless Networks Security
Turek, Lukáš ; Forst, Libor (advisor) ; Jirovský, Václav (referee)
This thesis compares the security of several wireless technologies and studies the security of networks based on IEEE 802.11 standard more in detail. Methods of securing are assessed in the view of resistance against eavesdropping, unauthorized access, DoS attacks and also attacks from inside of the network. Examples of configuration and in some cases also ways of attack are demonstrated. The thesis also studies related problems of secure passwords selection of and stored login data protection. At the end it suggests a way of securing a home network, a company network and a network of Internet service provider.

Environment for Master Orienteering Ranking Analysis
Kovářová, Lenka ; Forst, Libor (advisor) ; Schlesinger, Pavel (referee)
I accomplished analyse of potential formula schemes for veteran competitors ranking evaluation and I suggested their parameterisation. Next, I created an environment for the evaluation of veteran ranking that enables the competitors ranking calculation in accordance with the variables formulae that supports the proposed parameterisation and I, therefore, collected the results of orienteering races that were held in the last 4 years to get some data for the ranking evaluation. To display the calculated ranking I constructed a website. I computed the ranking of veteran orienteering competitors by use of selected formulae and then I suggested a modification of the Spearman correlation coefficient to prove the accuracy of each formula.

Internet Trade Center
Zápotocký, Radoslav ; Forst, Libor (advisor) ; Vrána, Jakub (referee)
The goal of this project is to create Internet Trade Center, a place, where users can create their own shop with custom products and categories. This shops will be independent on each other. It is designed to be easy modified, so theoretically it could be customized for completely different purposes. Moreover it will count with multiple languages from the beginning, so they will be working without any problems, and also with support for search engine optimization. The work can be eventually used as a guide to create similar applications.

Reservation and inrormation system for travel agency
Peška, Ladislav ; Forst, Libor (advisor) ; Skopal, Tomáš (referee)
The goal of this project is to create Reservation System for small or medium-sized travel agency. Essential is a support for On-line tour's reservation, management of capacities of the tours and also support for search engine optimization. Application is divided into two parts. The internal part allows travel agency employers to manage tours, clients, reservations etc. The part for travel agency clients allows them to search for tours, make reservations and check the state of their reservations. The application is written in PHP programming language and using MySQL database server.

Unsupervised learning based on images
Krupička, Radim ; Hlaváč, Václav (advisor) ; Forst, Libor (referee)
The aim of the project was to create an experimental environment for solving the children puzzle shape sorter . This environment serve as a testbed for various learning tasks of cognitive nature with image feedback. This puzzle is a demonstrator of the EU project COSPAL, IST-004176. The industrial robot CRS A-465 with six degrees of freedom and its control system is used. The scene is observed by one static camera. The system processes the images from the camera and the further robot movement is based on the reinforcement learning.

STalk - zabezpečená aplikace pro komunikaci
Gróf, Szabolcs ; Forst, Libor (advisor) ; Lukeš, Dan (referee)
In the present work we study the methods of using cryptographic algorithms to ensure the security of communication over computer networks and give a new perspective on the classic UNIX console chat program called talk. The thesis starts by describing the various protocols of the TCP/IP protocol suite, and also gives a brief description of how these protocols are used from the viewpoint of a UNIX programmer. It is followed by a cryptographic overview, mainly the description of the RSA and DES algorithms. Finally, the program's implementation and usage is described.
