S-38.149 Postgraduate Course in Teletraffic Theory

Fall 1999 course information

Traffic Modelling

Course Topic: In Fall 1999, the course will deal with Traffic Modelling.

Modelling the traffic that enters a network is one of the key issues in traffic engineering. The appropriateness of the model largely determines the reliability of any conclusions drawn with regard to quality of service, network dimensioning, traffic management etc. Poissonian traffic models that have traditionally been used in teletraffic analyses are no longer adequate for modern telecommunication networks. Traffic in the new networks, e.g. in the Internet, exhibit many interesting and exciting features, such as long-range dependence and fractal beahviour. A rich variety of new models has emerged to capture different features of the traffic. The purpose of the seminar is to give the participants a good knowledge of the state-of-the-art tools and methods for traffic modelling.

The course will mainly be based on a selection of scientific papers (both recent and classical) covering the following topics:

However, the participants are also encouraged to make their own proposals (concerning e.g. various practical aspects of traffic modelling).

Status of the course: The present course can be included in postgraduate studies on Telecommunications Technology (major or minor in S38). The credits can also be included in graduate studies on Telecommunications Technology / Teletraffic Theory.

To whom: The course is primarily meant for postgraduate students of telecommunications technology having an interest in understanding the traffic modelling and performance analysis of communication networks. Others having similar intrests are, of course, equally welcome.

Prerequisites: S-38.143 (Queueing Theory) and S-38.141 (Teletraffic Theory) recommended.

Course completion: The course will be arranged as a seminar (meetings once per week). The working language is English. To complete the course the student has to fill out the following requirements:

  1. Each participant shall write a report (about 15 pages) on the selected subject,
  2. give a presentation (about 60 minutes) based on the report,
  3. hand out 2 homework exercises in the subject,
  4. present the solutions to these exercises, and
  5. examine the solutions to these exercises by the others.
  6. Each participant shall also act as an opponent and
  7. write a summary (about 2 pages) on the topic (including the comments).
  8. Finally, each participant shall be present in seminar sessions (at least 80%), and
  9. do at least 50% homeworks given by the others.
Detailed instructions are given here. Note, however, that no examination is required in this year.

Organisation: The first meeting of the course will be held on Monday 13.9.1999 at 16 in room H401 of the Department of Electrical and Telecommunications Engineering. Then, from Monday 11.10. on, the seminars followed by the exercise class will be held weekly on Mondays 16-20 in room H401. Each seminar session consists of a presentation (about 60 min), the opponent's comments (about 15 min), and a general discussion (about 15 min). A more detailed schedule is given here.

Entry: Preferred way to inform about participation is through TOPI which is available for all students having a license to the university computers. Another way is to send an email to samuli.aalto@hut.fi

Study Credits: This course will be worth of 3 credit points.

Grading: The grading is based on the following three items:
