IK1611 Dimensioning of Communication Systems 7.5 credits

Dimensionering av kommunikationssystem

The proper design of communication systems is crucial for guaranteeing quality of service in communication networks. Queuing theory is the basis for performance evaluation and dimensioning of communication systems and networks. This course treats queuing systems with an emphasis on the classical models. The theory is applied for solving the practical communication system dimensioning problems.

Intended learning outcomes

After the course students shall be able to define the basic queuing models for different communication systems and dimension the systems in terms of router capacity, delay and throughput. This goal is both result oriented and easy to examine.  

Course main content

The course will cover the following:               * Terminology, definitions and basic formulas* Basics of probabilistic theory and Markov chains. * Modeling of communication systems in terms of delay, packet loss probability, system utilization etc.* Open and closed queuing networks. * The emphasis will be put on solving practical dimensioning problems for communication systems and networks.

Requirements for final grade

To pass the course one needs to pass a written exam (4.5 credits) and a project work (3 credits). The project work includes solving a real dimensioning problem, writing a report and presenting the result at the seminar.The final grade will be based on the results from the exam and project work. In the Spring semester 2007 grades 2-5 will be applied, i.e., grade 2 corresponds to not passed, grade 3: passed, grade 4: good and grade 5: very good. To pass the course the students shall be able to define the appropriate models for the Markovian systems and to dimension the systems according to these models. For higher grade the students shall be able to treat more complicated systems.From 2007-07-01 the grades will include seven levels (A, B, C, D, E, Fx, F).
