Description of achievement and assessment methods

The module examination consists of a graded written exam of 60 minutes duration and a literatur search and presentation project.

In the written exam students demonstrate by answering questions their theoretical knowledge of network reliability including the parameters, methodologies, and solutions. Students also demonstrate their ability to evaluate and analyse connection availiability and network reliability.

The capability for learning some particular topics more in detail will be examined through specific literature studies during the semester and the presentation of selected topics.

The final grade is composed of the following elements:

  • 70% final exam
  • 30% literature search and presentation of targeted topic.

Exam type: written and project work

Exam duration: 60 min.

Possibility of re-taking: In the next semester: Yes  At the end of the semester: No

Homework: Yes

Lecture: Yes

Conversation: No

Written paper: Yes

Recommended requirements

The knowledge of following modules are recommended:

  • Broadband Communication Networks

Contents

Introduction to network realiability and main concepts and parameters. Mathematical models (including failure and repair models). Basic span- and path- restoration techniques. Logical network desgn. Operational aspects of real-time restoration and self-organizing pre-planning agains failures. Restoration in IP networks. Techniques for mesh-restorable networks. p-Cycles.
