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.

The teaching methods depend on the type of course unit as specified in article 7 of the BUT Rules for Studies and Examinations.

For work during the course, it is possible to get up to 100 points. Elaborating 10 protocols up to 30 points can be gained during the laboratory exercises. The course is finished by taking a written exam, for which up to 70 points can be obtained.

1) Queuing theory - mathematical repsentation, random processes
2) Queuing theory - Markovian system of queue control
3) Queuing theory - qualitative parameters of queuing systems
4) Flow-control - congestion control and congestion avoidance
5) Flow-control - flow-control and error correction on data link layer errors
6) Protocol TCP - flow control in TCP
7) Protocol TCP - congestion avoidance in TCP
8) Quality of Service - basic requirements, IntServ, DiffServ
9) Quality of Service - marking, classification, metering, packet scheduling
10) Quality of Service - active queue management, DiffServ domain
11) Quality of Service support in wireless networks (802.11e)
12) Quality of Service support in mobile networks (IMS)

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.

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.
