Generator of illegitimate network traffic
Blažek, Ondřej ; Smékal, David (referee) ; Blažek, Petr (advisor)
The diploma thesis deals with the problems of DoS/DDoS attacks and development of a tool, in C lanugage, for generating them. In the first chapter the principles of DoS attacks targeting the internet and transport layers of ISO/OSI model are described and also according to their characteristics divided. Selected attacks on the application layer are also described here in detail togehter with protocols which they are based on. In the following chapter there has been created a comparison of freely available tools, which could be used as a attack generators. The practical part is dedicated to a development of a tool for DoS attacks, especially design, general description and usage. Further there is a summary of the newly created library, including results of web server testing, and extensions of a web interface, which is part of the developed tool.

Measurement of communication latency in IP networks
Bednář, Vít ; Vrba, Kamil (referee) ; Komosný, Dan (advisor)
Semestral thesis is focused on measurement of communication delay in networks. There is described creation of individual kinds of delay during the transfer in networks. Tools for measurement of delay are described and web pages are designed and made too. There is measured delay on choose 27 IP address with help of this page.
