  • First semester 2017 (Day)


This unit addresses the fundamental concepts and analytical tools for modelling, predicting and improving the performance of telecommunication networks. It also introduces simulation methods. First, performance modelling of a packet switch is covered. Then, a comparative analysis of routing algorithms is covered from a graph theory perspective. Third, methods to provide an integrated service to a set of traffic demands with different qualities of service are studied. Then, congestion in telecommunication networks is covered, and effectiveness of various congestion and flow control algorithms and protocols are investigated. The focus then shifts to individual links and nodes, and queuing theory is introduced and its applications in networks are analysed. Then, recent advances are studied to show how the analytical and simulation knowledge learnt in this unit could be applied in real life.


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

  1. Evaluate network performance problems using node or link-based analysis, graph theory and queuing theory.
  2. Compare and contrast different routing, traffic management, congestion control and flow control algorithms and protocols.
  3. Simulate complex networks and analyse their performance using discrete-event modelling.


Continuous assessment: 30% + Examination: (3 hours) 70%.

Students are required to achieve at least 45% in the total continuous assessment component (assignments, tests, mid-semester exams, laboratory reports) and at least 45% in the final examination component and an overall mark of 50% to achieve a pass grade in the unit. Students failing to achieve this requirement will be given a maximum of 45% in the unit.

Workload requirements

3 hours lectures, 3 hours laboratory and practice classes and 6 hours of private study per week
