Biography

Cristian Morariu received his Masters Degree from Technical University of Cluj-Napoca, Romania in June 2004 after 4.5 years of studies. His major at the Faculty of Automation and Computer Science, was performed in Computer Science. While holding an ERASMUS scholarship he developed his Master Thesis at the Swiss Federal Institute of Technology (ETHZ), Laboratory of Software Technology. Since September 2004 he is a doctoral student at the University of Zurich, Department of Informatics, Communication Systems Group. His main interests are in the area of IP accounting and distributed architectures for traffic analysis.

PhD project description

The goal of this doctoral thesis is the design and prototypical implementation of an architecture for distributed analysis of IP traffic. As network link speeds increase year-by-year having stand-alone devices that perform traffic analysis becomes unfeasible. A distributed platform for traffic analysis would leverage the processing requirements of such a task by combining resources of multiple devices performing traffic analysis. The thesis shall investigate three different areas of traffic analysis: capturing data on high-speed links, analysis of captured data, and storage of analysis results for further processing by third-party applications.

Brief description of the scope and objectives of the PhD thesis:

• Evaluation of existing traffic monitoring tools and approaches
• Analysis of requirements for a generic traffic analysis platform using at least two different scenarios
• Design of the architecture
• Prototypical implementation of the distributed platform for traffic analysis
• Evaluation of the approach based on the prototypical implementation
