Computer networks are ubiquitous Networks touch every part of our daily life
Web search Social networking Watching movies Ordering merchandise Wasting time

Computer networks are ubiquitous Networking is one of the most critical topics
in CS There would be no…
Big Data Cloud Apps or Mobile Computing
… without networks

Goals
Fundamental understanding about computer networks Layered approach covering routing algorithms and
protocols up the stack Not just how it works, but how did it end up that way? Issues arising with new popular applications online How might we rethink protocols and assumptions of the
past Focus on software and protocols
Not hardware Minimal theory
We will be putting concepts into historical perspective

Teaching Style
I am a network researcher Things make sense to me that may not make
sense to you If you do not understand something, do not be
shy to stop me and ask Seriously, ask questions!!! Standing up here in silence is very awkward I will stand here until you answer my questions
Help me learn your names Say your name before each question

Course = Lecture + Practice
Practice Homeworks (40%)
4 assignements with hard deadlines during the semester First one will be announced : 2nd October
And class participation [for extra points] Midterm exam (30%) [traffic analysis + basic calculations] Final exam (30%) [socket programming]
Minimum requirement: 50% At most 4 absences are allowed (but not encouraged)
for any reason Lecture
After a successfully passed practical part… Final exam at end of the semester

Cheating
Do not do it Seriously, don’t make me say it again
Cheating is an automatic zero Will be referred to the university for discipline
and possible expulsion
