Weekly outline

  • General

    In this course you will learn and understand how computer networks are built and run. You will be able to:
    • test and clarify your understanding of the networking concepts by connecting computers to form LANs, autonomous routing domains and interconnections;
    • test the performance of TCP versus UDP and of traffic control settings;
    • develop and test various communicating programs using sockets;
    • be familiar with IPv6 as well as IPv4 and the interworking between them;
    • understand congestion control, TCP and QUIC;
    • run Mininet in your computer and deploy real networks in an emulated environment.

    This is a master level course for master and PhD students.

    Lectures

    Lectures are on Thursdays 12:15-14:00 in room CM2 and simultaneously by zoom in room 631 4376 4890. Recordings are posted on youtube as soon as possible after the lecture. 

    Speakup

    We use speakup for polls in class. During the lecture, you can go to web.speakup.info in a web browser. Or you can download the speakup app for your smartphone. This works in class and also if you are attending the lecture on zoom.

    Lecture Notes
    • "Computer Networking : Principles, Protocols and Practice" by O. Bonaventure, 1st or 2nd edition:  pdf, epub, mobi
    • "Rate adaptation, Congestion Control and Fairness: A Tutorial" by JY Le Boudec: pdf

    Labs

    There is a lab every week, on Fridays 11:15-13:00 in rooms INF1 and INF019 (only for those who have only a Mac with processor M1) and 13:15-15:00 in room INM202 and INF019 (only for those who have only a Mac with processor M1). The lab session is simultaneously streamed on zoom in room 620 0940 7593, for those of you who are not allowed on campus or prefer to work from home; parallel breakout rooms will be setup as required. 

    The labs are designed to be done on your own machine for most students (except those who have only a Mac with processor M1) and do not require physical presence at EPFL. You can do them at any time. You can use the lab sessions, live and in zoom, for support; you can also use the questions and answer forum on moodle to ask questions about the lab (and about the lecture).

    Every lab lasts for 2 weeks, but for the last one. For each lab, you are graded by doing lab quizzes on Moodle. Lab quizzes have to be completed at the latest on the Wednesday that follows the last lab session for the current lab.

    In most labs, there is a more advanced section called research exercise, which is for bonus. Do it only if (1) you feel comfortable with all the rest of the lab and the lecture, (2) you have enough time and (3) you like the topic.

    Online Lecture Quizzes

    There is one online lecture quiz every week on lecture. The goal is to train your understanding of the lecture. It is also a training for the labs and for the final exam. The quizzes are mandatory, you are considered to have completed the lecture quiz when you achieve a grade of 70% or more. The lecture quiz grade only counts to determine if you passed the quiz or not, once you pass we don't use the lecture quiz grade. You must be up to date with your lecture quizzes in order to do lab quizzes.

    Exam

    There is one written exam in the exam session. It is closed book. We will provide you with a printed copy of the exam booklet, which contains formulas and material that is too tedious to be learnt by heart.  We recommend that you train with the old exams. Such conditions are subject to change if the covid situation imposes.

    Grading

    The course grade is the average between the lab grades and the final exam. More exactly:

    • Theory grade T = final exam
    • Lab grade = average of 7 labs ( last lab counts as one half)
      Research exercise bonus = average of all lab bonuses (max bonus is 0.5 in scale 1-6)
      L = min (6, Lab grade + Research exercise bonus)
    • Final grade = ½ ( T+L) rounded to next quarter integer.

    All grades except final grade are non-rounded.
