Data Communications and Networks

Course aim

To develop sound understanding of data communications and networking concepts, techniques, equipment and software. To develop an appreciation of the Internet architecture and protocols, as well as a sound understanding of the protocol mechanisms employed at the IP and Transport layers of the Internet.

Course content

Basic concepts in data communications and networking: access and core networks, circuit and packet switching, protocol reference models, protocol layers, standardisation. Example communication systems and networks.
The Physical Layer: signals and channels, channel capacity, transmission media, digital modulation, multiplexing. Low level communication mechanisms: serial vs. parallel, synchronous vs. asynchronous, example standards. Data access via public telecommunication networks .
Data Link Layer: purpose and functions, principles of error detection and correction, stop-and-wait and sliding window protocol mechanisms, example protocols.
Medium Access Control: static vs. dynamic channel allocation, multiple access protocols. Ethernet and Wireless LANs technologies. Overview of wireless data access technologies. LAN equipment: hubs, switches.
The Network Layer: purpose and functions, routing, congestion control, quality of service. The Network Layer in the Internet: IPv4 protocol and IP addressing, IPv6, routing in the Internet, Mobile IP.
The Transport Layer: transport layer services, transport layer protocol mechanisms, UDP and TCP protocols.
The Application Layer: overview of the Domain Name System, Electronic Mail, World Wide Web and HTTP, Streaming Audio and Video.
Overview of network security: basics of cryptography, symmetric- and public-key algorithms, digital signatures, key management, securing networks.
