431-462 Communication Networks

Students may not obtain credit for both this subject and 431-223 Telecommunication Networks.

431-325 Stochastic Signals and Systems.

On completion of this subject students should understand the basic principles of communication network design, the layered architecture, and network protocols. Students will obtain a good understanding of the way optimisation and random process models are used in network design, and will undertake a network design project.

Topics include network topologies for core and access networks; voice and circuit-switched networks; packet switching and multiplexing game; layered network architecture; physical layer multiple access (TDM, WDM); link layer protocols, Medium Access Control; network layer topologies, routing algorithms and protocols (IP); transport layer protocols (TCP); flow control, ARQ error control, analysis of utilisation; random process models for analysing delay; optimisation methods for network design, network reliability; quality of service issues; and LAN protocols, ATM, MPLS, protection and restoration. All concepts illustrated by examples from wireline, wireless and optical networks.
