Perfecting the analysis of 10Gbit/s computer network
Ťápal, Tomáš ; Polívka, Michal (referee) ; Škorpil, Vladislav (advisor)
The master’s thesis consists of several parts. Describes the technology 10 Gbps Ethernet. Analyzer Ixia and Endace presents, especially their use for traffic analysis and stress testing the network devices. It deals with documents RFC concerning the routers and switch testing. Thesis includes the reports of tests switches and router performed by RFC 2544 and RFC 2889 documents. Part of the thesis is dedicated to COMBO FPGA cards. Documentations to the analyzers is created in this thesis and macro is on the CD for presentation of measurement results.

Performace and Stress Testing Tool
Javorský, Daniel ; Veselý, Vladimír (referee) ; Ščuglík, František (advisor)
This thesis is concerned about performance and stress testing of Xtend product developed by Xura, Inc. Software development knowledge, theoretical knowledge of testing and testing tools are described in opening chapters together with key features and services provided by Xtend. Emphasis was put on implementation of performance and stress testing tool, which focuses on short-term and long-term testing scenarios and output of this tool serves Xtend developers. Part of this thesis also focuses on results of stress and performance tests.

A Tool for Robustness Testing of Web-Services
Zelinka, Tomáš ; Očenášek, Pavel (referee) ; Rychlý, Marek (advisor)
This project deals with testing of web services. The result of this work will be a tool for load testing of web services using fault injection in their communication. The first part of the project discusses the basic aspects of testing web services. The second part of the work is more focused on testing high loads in combination with fault injection. The tool will allow automated run of the tests. The distributed model of the tool was designed to simulate real loads. In the last chapter are summarized achieved results.

Automated creation of statistics of network traffic
Benedikt, Jan ; Frolka, Jakub (referee) ; Číka, Petr (advisor)
This Bachelor Thesis aims to process and present outcomes of stress testing. The frst chapter depicts basic terms closely connected to stress testing. Second part is concerned with the analysis of possible resolutions and their comparison between each other. The obtained theoretical knowledge is then applied to model sketch for a report, generated in form of the website. The model itself is created in JMeter program and it is written in the Java coding language. The generated website is programed in HTML, CSS and JavaScript languages.

Design of a Robotic Cell for Load Testing Purposes
Konečný, Tomáš ; Kubela, Tomáš (referee) ; Pochylý, Aleš (advisor)
This thesis is focused on design of a robotic cell for load testing purposes. At the beginning the aim of work is determined by objective testing. Next part is description of a test object, current work station and the present state of work. Further is determined one variant of solutions and are selected elements of the robotic cell. The design of layout follows especially with regards to safety and is processed simplified risk analysis. The second half of the work consists of developing a driverless robot design of the measuring device. The end of thesis is price calculation.

Stress tester
Shpak, Kyrylo ; Člupek, Vlastimil (referee) ; Zeman, Václav (advisor)
The bachelor thesis deals with the issue of stress testing. The aim of this work is to extend the JMeter tool with amplification modules of DoS attacks. The beginning of the work introduces the issue of DoS attacks, along with a description of selected attacks. One of the points of the work is to verify the functionality and find errors of the stress tester, which is a comprehensive system for testing the information and communication infrastructure based on the JMeter tool. The last chapter deals with the implementation of DoS attacks.

Stress Testing of Video Streaming Services
Kříž, Petr ; Ilgner, Petr (referee) ; Číka, Petr (advisor)
The bachelor thesis deals with the load testing of services for adaptive streaming of multimedia content. The thesis starts with a theoretical discussion of load testing and standards for adaptive streaming. The practical part deals with the creation of scenarios for load testing the created streaming server. Finally, graphs are prepared including commenting on the testing result.

Stress testing of computer networks
Bolek, Daniel ; Martinásek, Zdeněk (referee) ; Hajný, Jan (advisor)
Bachelor's thesis deals with stress testing of server running on operating system Linux. Theoretical part of this project briefly describes the history of Linux, choice of distribution Debian and the server's applications Apache and Vsftpd. Then I describe device Spirent Avalanche 3100, which is designed to generate load and interprets results of tests. Semestral project also deals with DDoS attacks, analyzes current state in this field and describe those DDoS attacks, which provides device Avalanche 3100. Then shows possible solution, how to proceed, if we want to design protection against DDoS attacks. Practical part of semestral project is focused on installation of a operating system Linux, implementation and configuration web, FTP and SSH server services and firewall settings. After that the server is subjected to stress testing. The main aim is to test the success of HTTP and FTP server for different load height and determine, whether size of downloaded file has an effect to response time of the server. The aim of following section is to measure the impact of the choosen DDoS attacks. Protection against SynFlood attack is tested in the last part.

Stress Testing of Internet Telephony
Šípek, Martin ; Ilgner, Petr (referee) ; Číka, Petr (advisor)
The thesis deals with the development of a module for JMeter that adds SIP stress testing functionality that was previously missing in the program. The theoretical part of the thesis deals with Internet telephony and codecs used in telephony. The SIP protocol is discussed in detail and the end of this part is devoted to stress testing. The practical part focuses mainly on the development of the proposed module, where the code of the module is described in detail, but it also deals with the installation and configuration of the Asterisk PBX on which the proposed module is tested. The results of this testing are analyzed at the very end of this thesis.

Performance testing of networks with Mikrotik components
Kaláb, Vojtěch ; Kubánková, Anna (referee) ; Mašek, Pavel (advisor)
The goal of the thesis is to develop and describe application for Mikrotik Network stress testing. The aplication is developed in high-level scripting programming language Python. The aplication allowed us to configure and display in diagram our connected routers and network stress testing. Theoretical part is focused on Mikrotik company, their development and products. Next part is about theory of network stress testing and graph theory. The last part is about aplications development, programming language Python and used tools and libraries.
