Hardware computer networks
FEKT-CHWSAcad. year: 2017/2018
In the introductory part of this course, the principles of routing in packet networks are discussed. The key properties of the distance vector and link-state routing protocols are analyzed. Subsequently, the mechanisms ensuring the Quality-of-Service in data networks and possible implementations of these mechanisms in active network elements designed for wired and wireless data communication are discussed. Based on the hierarchical network division, the switching nodes operating on individual layers are described in more detail. The properties of switching nodes using time division multiplex and space channel division are given. The issue of inner blocking, output port competition, queue blocking, multicast transfer, and cell selection algorithms are 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.

Planned learning activities and teaching methods
Techning methods include lectures, computer laboratories and practical laboratories. 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.
