Subject description
Standardisation. Information types. Information transfer modes (analogue, digital, circuit/packet oriented, synchronous, asynchronous, connectionless, connection-oriented, and signalling). Quality of service (errors, loss, delays, delay variation). Telecommunication traffic (traffic theory, lossy systems, queuing systems). Information type and transmission mode. Circuit emulation. Architectures of telecommunication systems (network, topology, protocol stack, communication planes). Message synchronisation (synchronous and asynchronous transfer, transparent transfer). Multiplexing/demultiplexing techniques (space, frequency, time, code division multiplex, statistical multiplex, packet multiplex, examples). Addressing. Switching and routing (principles, techniques, influence on quality of service, a more detailed description of some methods and algorithms). Medium access control (MAC methods classification). Fundamentals of flow/congestion control. Technologies/services convergence. A more detailed description of some typical transfer systems (TDM, PDH, SDH, data transmission through voice networks, IP networks, VoIP) and telecommunication networks (telephone networks, SS7, ISDN, Internet).
The subject is taught in programs
Objectives and competences
Understanding of different information transfer modes, telecommunication system architectures, and switching/routing methods used in telecommunication networks. Understanding modern trends of network convergence.
Teaching and learning methods
Lectures and laboratory tutorials, individual work.
Expected study results
After successful completion of the course, students should be able to:
- describe the operation of telecommunication networks,
- explain basic principles and methods of data transfer,
- calculate parameters of telecommunication traffic,
- suggest the most appropriate means of multiple access to common media,
- explain the cause of network congestion,
- analyse the influence of comutation and routing on quality of service,
- assess the operation of typical transfer systems, such as IP networks.
