521476S Computer Networks (fall 2006)

TOPICAL
  • In school year 2007-2008 the course was split into two separate courses, 521261A Computer Networks I and 521262S Computer Networks II, so that 521262S Computer Networks II replaces 521476S Computer Networks.
  • OBJECTIVES: The course gives a comprehensive description on computer networks, from underlying physical layer up to application layer and today's most popular network applications.

    CONTENTS: Physical layer, data link layer, medium access control sublayer, network layer, transport layer, application layer, multimedia, QoS, network management, network security.

    IMPLEMENTATION: Lectures (voluntary), laboratory exercises (voluntary), problem solving sessions (voluntary) and course work (mandatory). The course is passed with a final exam or with five intermediate exams, together with an approved course work. The course comprises of five parts, each dedicated to one of the five layers in the TCP/IP reference model. Each part comprises of lectures, a problem solving session and an intermediate exam.

    COURSE BOOK: TBD.

    PRELIMINARY KNOWLEDGE: Operating Systems.

    VOLUME: 6.0 op (3.5 ov)

    LECTURES

  • Period 3 (13.11.-15.12.06): Tue 10-12 (lecture hall L10), Thu 12-14 (lecture hall L5)
  • Lectures are given in English
  • LABORATORY EXERCISES

  • 4 voluntary laboratory exercises are taken during the course.
  • Each successfully completed laboratory exercise contributes 1 point towards your point total (see grading below).
  • PROBLEM SOLVING SESSIONS

  • In each of the five parts of the course, a problem solving session is organized for the benefit of the students between the last lecture and before the intermediate exam.
  • A set of representative problems are handed out at the end of the last lecture before the intermediate exam for students to train on in advance of the problem solving session, where sample solutions are presented.
  • Problem solving sessions are organized on Mondays at 8:15-9:45 on following dates (#1 20.11.06, #2 4.12.06, #3 18.12.04, #4 TBD, #5 TBD).

    COURSE WORK

  • Each student has to submit an approved course work to pass the course.
  • Firm deadline (no exceptions) for submitting the course work is 15.5.2007.
  • Course work is graded on scale approved or approved+. Approved+ contributes 2 points towards your point total (see grading below).
  • If students are found guilty of plagiarism, i.e. two or more students submit duplicate course works, all students involved will automatically fail the course, i.e. they lose all their performances in this round.
  • Detailed requirements TBD.

    PASSING THE COURSE
    To pass the course you need to:

  • 1) Score at last 10/30 points in the final exam (next and last opportunity on 5.10.2007) or accumulate at least 10/30 points from the five intermediate exams (each worth 6 points) taken at lectures. These two alternatives are not mutually exclusive, i.e. you can go for both approaches.
  • 2) Submit an approved course work, which is graded on scale approved or approved+. Approved+ contributes 2 points towards your point total.
  • 3) Participate in 4 voluntary laboratory exercises. Each successfully completed laboratory exercise contributes 1 point towards your point total.
  • 4) Accumulate at least 12 points in total. In other words, if you accumulate say 10 points from the intermediate exams or the final exam, you need to score at least 2 points from the voluntary labs and/or course work to pass the course.

  • GRADING
    Point total = points from final exam or intermediate exams (10-30) + points from course work (0/2) + points from laboratory exercises (0-4).
    Final course grade is based on point total as follows:
    12.0-15.0 -> 1
    15.5-18.5 -> 2
    19.0-22.0 -> 3
    22.5-25.5 -> 4
    26.0-36.0 -> 5

    SCHEDULE

  • On Tuesdays lectures start at 10:15 (lecture hall L10)
  • On Thursdays lectures start at 12:15 (lecture hall L5)
