FIK3506 Performance Evaluation for Network Engineering 7.5 credits

Prestandautvärdering för nätverkskonstruktion

Rather than cramming students with the vast volume of baroque queuing theory, this course intends to address more common analytical problems arising in the field of communication networking: (i) how to process simulation and experimental data in a scientific way?; (ii) how to model communication network systems and to analyse their performance metrics?

Though the dizzying variety of theories in the field makes it hard to distinguish the common set of widely applicable theories, the textbook of the course brings a concise set of such theories together in order to answer the above two questions, a part of which has been rarely introduced in the classical books and made accessible only through this textbook. While the interdisciplinary aspects of communication networking are being ever more spotlighted and contemporary networking engineering necessitates all-round engineers trained in theory as well as in practice, careful attention need to be paid to the fact that only a few selected theoretical results lend themselves to engineering problems. This course introduces and elucidates those theoretical concepts for performance evaluation of communication networking, encompassing modern statistics, point process theory, and queuing networks. Among them, Palm Calculus, which was named after Swedish mathematician, Conrad Palm, serves as a theoretical foundation to provide much widened viewpoints on top of queuing theoretical viewpoints.

Last but not least, it is unethical to make a wrong and hasty conclusion only because of the ignorance of suitable analytical techniques.

Will this course come useful to you?

One of the artistic aspects of performance evaluation lies in that seemingly trivial questions in everyday life are directly related to those encountered in the field. For instance, the following questions will turn out to be not only exquisitely relevant to engineering problems in networking but also crucial for avoiding common repetitious pitfalls in the field:

“Why do we feel that we wait relatively longer than others when shopping in ICA or COOP?” (Palm Calculus)

“Can we validate the ad for a ski resort, ‘capacity doubled, waiting time halved’?” (Queuing Theory)

Some more specific problems you may encounter while conducting research or development are as follows:

“If the data is not normal, what kind of method can be used for computing a confidence interval for an arbitrary performance metric?” (Confidence Interval)

“It is well-known that determining whether truncated data follow power-law or not is an intricate problem. How can we test and quantify the goodness of a certain distribution to the data?” (Tests)

“It takes months to estimate by simulation the probability of a very rare event, e.g., a bit error rate of 10-10. Is there any other way around this?” (Discrete Event Simulation)

Answers to all the aforementioned questions and their implications will be taught in the course.
