Computer Networks II spring 2013


In this course, you are expected to do an oral presentation of a selected topic. This task is mandatory to get a pass grade. Students who aim at grade "4" or "5" should in addition to their own presentation submit constructive feedback to three other assigned presentations.

IMPORTANT NOTE: In order to be able to submit feedback to other students, you must have handed in your own presentation before the given deadline.

The presentations should introduce the assigned topic to other students by giving a good overview and explanation. The target audience for the presentations are your fellow students in the course.

Even though this task is called "presentation", it actually involved a number of subtasks:

  • Forming a presentation group of two students
  • Pick a topic. Deadline for this: Feb 1:st at 16:00
  • Doing a literature search for the chosen topic
  • Presenting the chosen literature to the teacher. Deadline for this: Feb 15:th at 16:00
  • Reading up on the topic
  • Preparing what to show and what to say
  • Recording the presentation
  • Submitting your presentation to the student portal Deadline for this: Mar 8:th at 16:00
  • Watching and giving feedback to three other presentations assigned to you (only needed if you aim at a higher course grade than a "3"). Deadline for this: Mar 15:th at 16:00

Some of the subtasks have a hard deadline associated with them. If you fail to meet any of the deadlines for the subtasks, it may affect your overall grade negatively but most importantly, it will make it harder for you to get enough time to do a good presentation.

Forming a presentation group

Presentations will be done in teams of two students. Find a presentation partner either by asking around in the classroom, or by using the student portal to mail other students in the course.

Pick a topic

In the student portal, we provide a list of suggested topics that you can choose your topic from. Each topic can only be covered by one presentation group of two students- if your favorite topic is already taken you have to pick another.

You can also chose a topic of your own that is not on the list. However, your choice must first be cleared with the teaching staff before you can continue with the preparations. To ensure that you get your topic cleared before the deadline, you must present it to the teacher no later than 48 hours before the deadline for picking a topic.

Chosing your topic and forming presentation groups is done in the student portal.

Note that there is a deadline for picking a topic. You must form a presentation group and get your topic cleared with the teacher before that deadline if you plan to do a presentation.

Doing a literature search

Once the topic is chosen, you must find information about what you are going to present. Students are expected to be able to do a literature search on their own that extends beyond Wikipedia into at least 3-5 whitepapers, research papers, books etc.

This is a very important part of the preparations, so be careful when finding information sources and selecting which to use. For the presentations in this course, you should need something line 3-5 references to read up on.

Note that there is a deadline for doing the literature search. When you have completed this task and come up with 3-5 references, you must have them cleared with a teacher before continuing.

Reading up on the topic

When you have finished your literature search and gotten your references cleared with a teacher, you start reading up on the topic that you will present. During your reading phase, you may discover that you are missing some information in the references you have found. If so, go back one step and locate references needed to be able to do a good presentation.

Preparing what to show and what to say

You will record a presentation that at a minimum contains slides and your presentation as an audio track. However, you are free to extend that presentation to demonstrating software, including an image of yourself in the presentation etc. - as long as your presentation can be contained in a video file of 10-15 minutes.

When preparing slides, it is a good thing to have simple, concise slides that do not contain too much (spellchecked) text. Structure your presentation so that there is a natural flow in what you present. What is being shown on the screen in your video should be clearly readable even at moderate resolutions like 800x600 points.

Write a manuscript for your audio track and rehearse what you are going to say until you think it is good enough for recording.

Recording your presentation

Once you have prepared, it is time to record the presentation. There are several options to chose from in terms of software being used. The formal requirements on the file that you submit are that:

  • It should be 10-15 minutes long
  • It should contain at a minimum video and your voice as an audio track
  • It should be stored in MP4 or AVI format
  • It should preferably use common codecs for audio and video to ease playback for other students

This means that you need access to a computer with audio recording capabilities. If that is a problem for you, contact the teaching staff ASAP and we will help you resolve that situation somehow.

There are many different pieces of software you can use to produce a recording. Some presentation software includes the option to record audio to a presentation for sharing or broadcasting. A more general approach is to produce a screencast, where you record a part of your computer screen together with audio. One free web-based service for producing screencasts is Screencast-o-matic, which works on both Linux, OS X and Windows. There are also standalone screencast-producing software that can be downloaded. If you only need to record audio, Audacity is a free cross-platform software for that purpose.

The resulting video file must use a standard codec in an MP4 or AVI container format and be able to play under Linux, OS X and Windows without installing any extra software. Please try to keep your file sizes down by having low frame rates and a reasonable resolution.

We will provide a discussion area in the student portal where you can ask questions and give other students tips on what software to use and how to produce your presentations.

When your presentation is finished, it should be uploaded to the student portal.

Submitting your presentation

To participate in the opposition/feedback round, upload your presentation before the deadline specified at the schedule page.

Please follow the instructions below when uploading the presentations.

In the student portal page for this course, there is a discussion forum part named "video presentations". Your presentation should be submitted as a new topic in that forum.

  • Login to the student portal and go to the page for this course
  • Enter the video presentation by choosing "Video presentations" below the "Forums" heading in the left margin
  • Start a new topic by clicking the "New topic" button
  • The new topic editing box appears
    • As subject, type the name of your chosen presentation topic.
    • In the message body, specify:
      • The names of all members in your presentation group
      • The references you have used as background material for this presentation (titles, authors and links if applicable)
    • At filename, click the button to pick your video file from the hard drive (MP4 or AVI format)
    • At description, specify your chosen presentation topic agin
    • Press Submit
  • Verify that the video attached to your new entry can be downloaded and viewed
    • If possible, do this on another computer than the one you recorded on to ensure that your choice of codecs works for others.
  • There, you're done!

Opposition / Feedback

After the deadline for submitting your video presentations, we will produce a list that specifies who will give feedback to whom. Each student will be assigned three presentations to give feedback on if they aim at a grade higher than "3". Note that this subtask is not mandatory if you settle with grade "3".

The list will be e-mailed out to all students so you know who to give feedback to, but also posted to the video presentations forum in the student portal.

Once you have been assigned three presentation, your task is to view those presentations and produce constructive feedback to that presentation. This means that you should point out what you thought was particularly good, interesting and relevant in the presentation so that the presenter get feedback on their performance. The purpose of the opposition/feedback is not to bash other students and point out flaws; the feedback should be given with a positive attitude with constructive comments and suggestions (if you have any). If it should be the case that you find severe flaws in the presentation, take that off-line with the presenter rather than in the forum online.

To submit your feedback, go to the discussion thread that has the video presentation you are giving feedback on and type in your feedback as a reply to that.

If you want to give constructive feedback to more presentations than the ones that have been assigned to you, feel free to do so.


The presentations are graded by the teaching staff on a scale 0-5 where 5 is extremely good, 3 is average and 1 is borderline unacceptable. For the presentations, there are two set of points handed out - P1 and P2.

  • P1 points are handed out depending on the actual oral presentation; how well you present and structure the material you have chosen to present.
  • P2 points are handed out depending on the contents of your presentation; the material chosen, difficulty level, choice of references.

A zero score on P1 or P2 means that your presentation has not passed and must be re-done at a later time.

For students who submit feedback to other presentations, the feedback is graded 0-3 OPP points depending on how constructive and useful your feedback is.

Late hand-ins

If you submit your video presentation after the deadline specified on the schedule page, you will not be able to give feedback to others. Late hand-ins will be graded at a later time, possibly not before the end of the academic year.
