Annotation
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.
Course outlines
1. Introduction, basic terms, ISO/OSI model
2. Systems with distributed parameters, physical channel (metallic, optical and wireless) and its features
3. Communication channel models (AWGN, BSC, ...), narrowband analog and digital modulations
4. Spread-spectrum communication (DSSS, FHSS, OFDM …)
5. Information source entropy, source and channel coding, channel capacity
6. Error-detection and error-correction codes (finite fields, linear a cyclic codes)
7. Information security, symmetric and asymmetric ciphering
8. Application of ciphering algorithms, key distribution, certificates, digital signature
9. Data transfer types, multiplexing, media access control methods
10. Physical and logical topologies, ARQ methods, addressing and internetworking, industrial distributed systems and computer networks

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.
