Looking at information and telecommunication networks, we see that the transmission of confidential data via Internet is becoming more frequent every day, therefore, it necessary our be reliably protected from various threats, vulnerabilities day try to gain access network intercept data, neutralize, resources. That why, in time, protecting software hardware viruses than ever, not just a proble...

In telecommunication networks, as in many other areas of science and engineering, proliferation of computers as research tools has resulted in the adoption of computer simulation as the most commonly used paradigm of scientific investigations. This, together with a plethora of existing simulation languages and packages, has created a popular opinion that simulation is mainly an exercise in comp...

Global telecommunication networks and services are among the enterprises having the highest volumes of real-time data. A voice network may complete more than 250 million calls per day. Each is described by one or more events, yielding a total of tens of gigabytes of data daily. Wireless, Asynchronous Transfer Mode (ATM), frame relay, Internet Protocol (IP) networks and higher-level services on ...

Acknowledgements The research presented in this thesis is motivated by a joint project of T-Systems Nova GmbH Technologiezentrum and the Konrad-Zuse-Zentrum für Informationstechnik Berlin, financed by Deutsches Forschungsnetz e.V. Working on this project was very instructive for me. The cooperation with Jörg Rambau, Diana Poensgen and Sven O. Krumke was very pleasant. I wish to thank them for t...
