16. Background Knowledge • Advanced courses on data networks • There will be networking terms that I assume you have learned about at some point. • The tools are all data network specific. You’ll definitely need to know how the TCP/IP network works and the advanced research-oriented ideas. • This will be a difficult course if you do not have sufficient background.

17. Software Skill • Unix • C/C++ • Experience with scripting language

18. Equipment Requirement • A laptop of your manipulation • Installing FreeBSD • Installing tools • Bringing in-class some Friday afternoons • Alternatively • A PC of your manipulation • A Laptop with network capability for some Friday afternoons

20. Nature • An advanced course on networks experiments • Basics • Tools • Real experiments • For graduates students • Serious • Responsible • Spontaneous

21. Objectives • Revisiting the fundamental experimental design and analysis • Examine the workload model and experimental design suitable for network research • Emphasizing the details of measurement, simulation, and testing tools for network research • Practical training of theory learned in real-world problems

22. Scope • The network experiments • Performance evaluation in general • The target system, I.e. data network • The system • The workload • The metrics • The tools • ns-2 • dummynet • tcpdump and libpcap
