Philosophy of open systems interconnection, theory of layer models.13
Types of physical media: guided ( copper, fiber), unguided (radio waves) and applications. Physical media, measuring basics (attenuation, crosstalk, bit error rate, jitter).23
Communication processes of physical layer: multiplexing methods (FDM, OFDM, WDM, TDM, STDM, CDMA). 33
Communication processes of physical layer: digital modulations: baseband transmission (line codes, clock recovery, bandwith efficiency, scramling), passband transmission single and multi-carrier modulation). 43
Communication networks in physical layer: digital subsciber lines (xDSL), cable TV (DOCSIS), fibet tr the home (FTTx, GPON).53
Datalink layer communication techniques. Frame types, frame assembly, frame snychronizing. Error handling processes, error correction codes, error detection strategies. Cyclic redundancy check (CRC) methods and efficiencies. Bit Error Rate (BER), frame error rate, error statistics. Traffic engineering (error and flow control) in the datalink layer protocols. Sliding window protocols. HDLC and PPP frames and their applications.63
Consultation, test.73
Protocols of the network layer, theory of IP (Internet Protocol) routing. Packet structure of IPv4 and IPv6 protocols, cooperation with datalink layer (ARP- Address Resolution Protocol, DHCP - Dynamic Host Configuration Protocol, ICMP - Internet Control Message Protocol).83
Theory of IP Quality of Service (QoS), implementations. Integrated Services, Differentiated Services, traffic shaping, traffic policing. IP multicast theory and applications.93
Transport layer protocols. TCP/IP protocol stack (Transmission Control Protocol, User Datagram Protocol). Security concerns of network communication, encryption, authentication and authorization. Firewalls and Virtual Private Networks.103
Application layer protocols. Domain Name System, Domain Name Service. Meanings of different DNS records (SRV, MX). Hypertext Transfer Protocol (HTTP) and Secure HTTP (HTTPS).113
