Modern Network Technologies

FEKT-NMOSAk. rok: 2015/2016

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.

Výsledky učení předmětu

After 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.


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