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
