This subject provides knowledge and skills necessary for analysis, design modelling and optimisation of telecommunication networks.
This subject is a collection of analytical, numerical and optimisation techniques relating to network modelling and optimisation.
Topics in this subject can be generically applied to wired or wireless networks and are not limited to any specific type or tier. More specifically, the subject will include:
- Topological modelling of telecommunication network;
- Capacity planning and design; problems involving flow;
- Content and data delivery; supply and demand in telecommunication networks;
- Network cost optimisation with flow considerations;
- Collision detection; spanning trees, ethernet and its application;
- Routing protocols; shortest path problems;
- Application of evolutionary computation in network design and optimisation (will be presented subject to time availability);
- Quality of service and class of service (core network); Multiprotocole Label Switching (will be presented subject to time availability);
- Designing for performance, consideration of service level agreements in network design;
- Survivability, reliability and availability in network design; Designing fault tolerant network; Self healing design techniques; Fault detection mechanisms;
