Course detail

Modern Network Technologies

FEKT-MKC-MOSAcad. year: 2020/2021

The course makes the students familiar with recent trends in the fields of modern network technologies especially from the viewpoint of control algorithms and mechanisms implemented into communication protocols. The first part of the course provides sufficient mathematical background from queuing theory. It is followed by a detailed analysis of flow-control methods on the data link layer of the OSI/ISO Reference Model. The next part of the lectures is oriented to the control mechanisms implemented in the TCP transport protocol. The last part deals with the topics of Quality of Service support, from basic principles up to implementation details in mobile and wireless networks.

Learning outcomes of the course unit

Completing the course, students will have a detailed theoretical and practical overview of flow-control mechanisms on different levels of the OSI/ISO Reference Model. Additionally, they will have formed an overall view of the way quality-of-service support mechanisms used in fixed, wireless and mobile communication networks.

Prerequisites

The subject knowledge on the Bachelor´s degree level is requested.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Techning methods include lectures, computer laboratories and practical laboratories. Course is taking advantage of e-learning (Moodle) system.

Assesment methods and criteria linked to learning outcomes

For work during the course, it is possible to get up to 100 points. Up to 30 points can be gained during the laboratory exercises by passing the test. The course is finished by taking a written exam, for which up to 70 points can be obtained.
Due to the restrictions caused by the COVID-19 situation, the final exam of the course will take place in a distance (online) form.
