Course detail

Modern Network Technologies

FEKT-MPA-MOSAcad. year: 2023/2024

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.

Rules for evaluation and completion of the course

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.
Attendance at laboratory exercises is compulsory, justified absence in a laboratory exercise can be made up during the credit week after prior arrangement with the instructor.

Aims

The aim of the course is to introduce new principles and methods implemented in modern network technologies. The course is oriented mainly to different aspects of Quality of Service support in packet networks.
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.
