  • Second semester 2019 (On-campus)


(FIT9135 or FIT5135 or FIT9020) or equivalent

Basic network systems knowledge, understanding of probability theory.


This unit will cover network design, performance modelling and analysis. Queuing models (M/M/1, M/M/k, M/M/k/k, M/G/1), networks of queues. Multi-access systems (splitting, reservation, carrier sensing), routing techniques (shortest path, Bellman-Ford, Dijkstra, adaptive routing, flooding). Quality of service (QoS) aspects, flow control, connection admission control and other traffic management functions - ATM, IntServ and DiffServ models. Network topology design and performance modelling, design considerations for local or wide area networks, including GEPON, cable and wireless networks. Introductory probability and graph theory.


At the completion of this unit, students should be able to:

  1. explain and construct queuing models for performance modelling of networks;
  2. explain multi-access systems including splitting, reservation, and carrier sensing;
  3. explain analysis of routing protocols commonly used on the Internet;
  4. explain and apply traffic dimensioning for circuit and packet switched networks, including VoIP and multimedia;
  5. explain and apply design considerations for local or wide area networks, including GEPON, cable and wireless networks;
  6. explain the analysis and evaluation of the operation of a local or wide area telecommunications network.


NOTE: From 1 July 2019, the duration of all exams is changing to combine reading and writing time. The new exam duration for this unit is 2 hours and 10 minutes.

Examination (2 hours): 60%; In-semester assessment: 40%
