Vital Information

• Course : 網路模擬與測試• Taught by : 黃寶儀• Class No. : 921 U7400

• Credit : 3 units


For Some of You

• The first non-English course taught in English

• All communication in English, including– Lectures– Homework– Exams– In/off-class interaction


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

Office Hour

• By appointment

• Vote for a common slot next week


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


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




• Your responsibility– Homework– Term project



Nature

• An advanced course on networks experiments– Basics

– Tools

– Real experiments

• For graduates students– Serious

– Responsible

– Spontaneous


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


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
