Number of ECTS credits


Mode of study

Not applicable.

Entry knowledge

Students who are going to attend this course should be able to:
- use several numerical systems and conversions among them,
- explain and use elementary units which are common in the area of information and communication technologies (ICT), e.g. data size, transmission speed,
- use elementary terms from the ICT area, e.g. operating system, memory, process,
- describe the architecture of basic network models, i.e. TCP/IP and ISO/OSI,
- describe the basic application protocols for user data transfer from the TCP/IP suite,
- list routing protocols used on local-area level.
Work in the laboratory is conditional on a valid qualification of a student according to the Decree No. 50/1978 Coll. (Czech rule), which students must obtain before starting the course. Information on this qualification is given in the Dean's Directive on familiarisation of students with safety regulations.

Rules for evaluation and completion of the course

Up to 30 points for laboratories (points are earned for independent assignments, test and laboratory protocols). The credit is conditional upon the student's attendance, submission of all individual assignments and obtaining at least 15 points.
Up to 70 points are awarded for the written examination. In order to pass the course, it is necessary to obtain a total of at least 50 points (the sum of points from the labs and the exam).
Attendance at laboratories is compulsory, properly justified absence can be made up after prior arrangement with the instructor.


The goal of the course is to provide students with comprehensive orientation in the field of advanced communication techniques, especially on the network layer and application layer and also with specific issues such as design and specification of communication protocols.

Students who have completed this course are able to:
- demonstrate the differences between ISO/OSI and TCP/IP network models, explain the essence of these models,
- analyze the task of network layer with IP protocol,
- identify and interpret several levels of address translation used in IP networks,
- explain the principle of protocols used for redundancy of access to default gateway,
- explain the essence of multicast data transfer,
- explain every aspect of IPv6 protocol and related issues,
- assess the suitability of transport layer protocols for particular applications,
- explain issues of autonomous systems existence,
- apply multi-level routing with BGP protocol,
- design and analyze own communication protocol.
