Course Information

This course has structure that is based on continous assessment in the form of seminars, presentations, reviews and labs without any written examination at the end. Course grades are based upon student activities throughout the course which means that students in order to pass the course must be active throughout the entire course.

If you are a student in this course, you should carefully read through the information about the course structure, assessment and course grades on this page to ensure you are well informed about the rules that apply to this course.

Prospective students who are interested in taking the course but have not signed up should contact the student councellor asap. Be aware there is a limit on how many students we allow into the course and that we do not accept new students after the first week of studies.

Theory part

Course start

The course starts off with an introduction lecture where the course structure and overview of the material covered in the course is presented. At this lecture, student groups will be formed for the rest of the course. If you are alredy admitted to the course but for some reason can not attend the first lecture, contact the teacher no later than January 14 on this matter.

Themes

After the Course start, the rest of the theory part of the course is divided into 5 themes. Each theme consists of a group work and three seminars of student presentations. There is also the possibility to hand in reviews (within some limits, read on about this) of papers within each theme.

Group work

The students are divided into groups of 4-5 students at the course start. Before each group work session, all group participants must read an assigned article. During the scheduled time, group members go through the article and prepare a 15-minute presentation of the paper to be held by one of the group members at a seminar a few days later. In order to pass, you must actively participate in at least 4 out of 5 group work sessions.

Seminars

During the seminars, all the papers in the theme are presented before all other students. Presentations should be well prepared and must not exceed 15 minutes in time. Each presentation is graded on a scale 0-5 with respect to: oral presentation, material covered, presentation structure, and ability to answer questions afterwards. This gives a total grade of 0-20 on the presentation. In order to pass, you must actively participate in at least 80% of the seminars and give a presentation once. For seminars that you do not participate in, you must submit a make-up review.

If you can not attend one of the seminars, you can make up for this by submitting a make-up review of the three articles presented at that seminar within 2 work days after the seminar. This is done by reading the papers presented at the seminar you missed and write up a review that is submitted via the online reviewing system within 48 hours after the seminar you missed ended.

Reviews

Reviews are not the same as make-up reviews: Make-up reviews is something you write when you could not attend a seminar. Reviews on the other hand, is something that you are expected to write during the course. Read one of the star-marked (*) papers of another group and submit a review of that paper no later than 24 hours before the seminar at which the paper will be presented begins. You can only submit one review from each block.

You can not submit a review of a paper for a seminar that you write a make-up review for - you are only able to review papers presented at seminars that you later attend. In order to pass, you must throughout the course have submitted 2 reviews that got a pass grade. In any case, you are not allowed to submit more than 4 reviews in total (make-up reviews not counted into this limit).

Each review is graded on a scale F,3,4,5. See here for an introduction to how to write a review using the online system, and what we expect from a review and will look for when grading it.

Note that only papers marked with a (*) in the reading list is available for submitting a review of.

Grading

  • Group work is graded based upon active participation. You must be actively participating in at least 4 out of 5 group works. You are allowed to skip one of the group work sessions.
  • Seminar attendance is graded upon participation. You must attend at least 80% of the seminars. For seminars that you miss, you must write up a make-up review within 48 hours of the seminar. You are allowed to skip one seminar without having to write a make-up review, but that is all the slack there is for this part of the examination.
  • Seminar presentations are graded on a scale 0-20 by handing out scores 0-5 regarding oral presentation, material covered, presentation structure, and ability to answer questions afterwards.
  • Reviews are graded upon content on a scale F,3-5. You must have 2 reviews that receives a pass grade and are not allowed to submit more than 4 reviews in total. You can not review a paper that was presented at a seminar that you are writing a make-up review for. Neither can you review a paper presented by your group.

Your theory part score is calculated as follows:
10 * <# of group works you attended> + 2 * <your presentation score> + 2 * <sum of your grades for 2 passed reviews>

This gives you a score between 0 and 100. 0-59 points equals a "F" grade, 60-69 points give you grade "3". 70-85 points give you grade "4" and above 85 points give you grade "5".

Given that both labs are passed, this grade will equals your course grade.

Make-up for missing points

If you:

  • Miss two of the group work sessions, OR
  • Miss more than 20% of the seminars and do not file corresponding make-up reviews within the given time limits for two seminars (one freebie included), OR
  • Only have one review with a pass grade

...if you have only one of these things standing between you and a pass grade, then you are allowed one extra chance to make up for your missing points. The teacher will contact you at the end of the course with further details on how this will be done. If you do not manage to compensate for the missing points at that occasion, you will fail the course this year.

However, if you have been away from more than 2 group work sessions, or if you have missed more than two seminars that you did not already make up for, or if you have not received a pass grade for any of your submitted reviews - then this means that you will fail the course this year.

If you fail the course this year, this means that you must retake the course another year.

Lab part

The lab part of the course consists of two labs that are graded on a pass/fail scale. In order to pass the lab part of the course, you must receive a pass grade on both labs.

Each lab has a deadline associated with it. Submitting your lab before the deadline guarantees you to have the lab graded during the course, If you submit your lab after the deadline, we will grade it during the course if it reaches us before we have finished grading all the labs that were handed in before the deadline. If you submit your lab after we have finished grading, we will grade it at a later point - probably not until after the end of the academic year in August. If you submit your lab after the end of the academic year (i.e., after the last day of re-exams in August), it will be silently ignored and you will thus fail the lab part of the course.

If you have handed in a lab submission that is a good attempt but has some minor flaws, you will get a second chance to fix these errors. If your lab still have cruicial errors after the second chance submission, you will fail the lab and thus the lab part of the course. If your first attempt of hand-in was not even closely correct, you will not get a second chance and thus fail the lab part of the course.

Getting through

The easy way to pass this course is to:

  • Attend all the group work sessions, maybe miss only one if needed
  • Attend as many seminars as possible (you are allowed to skip one without a need to compensate for that)
  • If you miss a seminar - write a make-up review shortly (within 48 hours) of the seminar you missed
  • Do a good job presenting a paper at one of the seminars
  • Put some effort into writing two good paper reviews for papers presented by other groups.
  • Do the two labs on time as correctly as possible

...it's really not harder than that!

Litterature

There is no official textbook for this course - you will mostly read research articles within the field of computer networking.

Cheating

Don't do it. Seriously. It is not allowed and we will report anyone suspected of cheating to the disciplinary board.

It is not allowed to include large portions of the text in an article you are supposed to review in the actual review - your review must be written by you in your own words.
