Semesters Winter
Completion Assessment + Examination
Language of teaching Czech
Extent of teaching 4P+2L
The subject is focused on communication principles used within the distributed systems (DS). Initially the physical layer media are described, including communication channel models and analog and digital modulation techniques. Information theory is introduced together with coding methods for error detection, correction and/or information security. Next the general link-layer algorithms are explained (addressing, media access control, flow control, ARQ methods ...). Finally the most widely used distributed systems technologies are presented together with the family of TCP/IP protocols and typical distributed systems applications.
Study targets
To acquaint students with principles of communication within the distributed systems in order to be able to identify strong and weak points of particular technologies, to be able to use them in the right way and to be able to integrate them into large scale industrial control and data acquisition systems.

Exercises outlines
Laboratories are focused on practical application of theory received at lectures. It is required for students first to study the laboratory task instructions and necessary literature and finally to prepare the report from measurement, containing measured results and their correct processing. Final results should be discussed and justified.

13. TCP / IP family protocols, IP protocol, ARP, DHCP, ICMP, NAT,
14. Transport protocols of the TCP / IP, UDP, TCP, RTP family, data flow control, congestion control
Laboratory exercises will be focused on the practical acquisition of theoretical knowledge. They will require home preparation in the form of self-study, subsequent elaboration of a protocol evaluating the measured or otherwise obtained results, their agreement with theoretical assumptions and justifying any differences.
The credit project will focus on the practical implementation of data transmission with defined properties in the IP network environment.
