Course detail

Hardware of Computer Networks

FEKT-BKC-HWSAcad. year: 2023/2024

The course deals with the description and importance of the required hardware and selected protocols used for service and management of wired and wireless data networks. Following the hierarchical division of a network, switching nodes designed for individual hierarchical levels are described in more detail. The inner structure of the switch and router is described in more detail and also the operations performed on the data units are discussed. The issues of inner blocking, output port competition, queue blocking, multicast transfer, and cell selection algorithms are discussed. The key-properties of selected distance vector and link-state routing protocols are analyzed. Finally, the mechanisms ensuring quality of service in data networks and possible implementation of these mechanisms in switching nodes, and techniques ensuring the security and protection of the data network are also discussed.

Entry knowledge

The basic knowledge in the area of data communication and the used means of the data communication is expected.

Rules for evaluation and completion of the course

For work during the course, it is possible to get up to 100 points. Elaborating 10 protocols and passing one test, 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.
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.


The aim of the course is to make students familiar with components used mainl yin local area networks, inner principles of active elements, their configuration and key communication protocols of wired and wireless networks used by these active elements.
After completing the course, students will have the necessary knowledge and be able to describe the principles and inner architecture of active elements used in communication networks, to describe the control mechanisms and protocols, and be familiar with the basic setup and use of current network elements.
