The 2 best results at research exercise tests are allowed to give a presentation to the class
Presentation is graded RP increase your final grade by +0.0 ( 1) to +0.25 ( 6)

Some of you had a bachelor course on TCP/IP networking
They can try to escape the first module of the course
Take the escape test (today at 14:15 in INM 201) If test successful you are allowed to:
Skip lectures Module 1 Do research exercise now and grades replaced by escape test E and research exercise report grade RR

« I want this course to teach me all the details of all networking protocols »
ex: how to setup my NAT on my ADSL modem
Viewpoint 2: « TCP/IP is a mountain of details, I will learn when and if the need arises »
thus I do not need this course
We will use the RAKE philosophy ‐ Depth in carefully selected labs ‐ Extrapolation (Research Exercise)
14
Computer networking is ≈ 50 years of design experience
First paper on packet switching: 1961 (Kleinrock) First router built (connection oriented): 1969 (ARPAnet) TCP/IP is not a random collection of protocols, it is based on a few ideas
in this course we will learn the concepts “The devil’s in the detail”
it is easy to misunderstand concepts if you do not have practical experience: ex: difference between a router and a bridge ?
in this course we will gain practical experience by carefully selected practical
15
I will try and teach you to always ask first
Why was this stuff invented, what problem is it solving ? What is it doing?
before asking:
How does it do its job ?
This is important if you plan to become a technical leader or manager !
16
You will know enough concepts and have enough practical experience to
undertake a project that uses TCP/IP look credible at a technical meeting (ex: IETF meeting) quickly learn by yourself the details you need to know, when you need to know them
