Be Aware
• Homework and exams are accepted only in
English
• Credits are granted only when the English is
comprehensible

Though to avoid confusion…
• Please make sure your names are clearly
written in Chinese.

Think of it this way:
I get to be an exchange student
without going physically abroad.
Some Suggestions
• Read the corresponding material/slides
before a lecture
• Review the recording of a lecture speech
– Lectures will be recorded and put available in
mp3 format

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.

Software Skill
• Unix!
• C/C++
• Experience with scripting language

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 realworld problems
