Course detail

Modern Network Technologies

FEKT-MMOSAcad. year: 2019/2020

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.
