Hardware of Computer Networks
FEKT-BPC-HWSAcad. year: 2018/2019
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.
Learning outcomes of the course unit
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.
Successful completion of the courses Data communication and Network Architecture is expected.
Recommended optional programme components
Recommended or required reading
Planned learning activities and teaching methods
Techning methods include lectures and laboratory exercises. Course is taking advantage of e-learning (Moodle) system.
Assesment methods and criteria linked to learning outcomes
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.
