Multimedia Network Design

This subject has the following teaching availabilities in 2008:

For the purposes of considering request for Reasonable Adjustments under the Disability Standards for Education (Cwth 2005), and Student Support and Engagement Policy, academic requirements for this subject are articulated in the Subject Overview, Learning Outcomes, Assessment and Generic Skills sections of this entry.

It is University policy to take all reasonable steps to minimise the impact of disability upon academic study, and reasonable adjustments will be made to enhance a student's participation in the University's programs. Students who feel their disability may impact on meeting the requirements of this subject are encouraged to discuss this matter with a Faculty Student Adviser and Student Equity and Disability Support: http://services.unimelb.edu.au/disability

• Traffic flow problems: shortest path, spanning tree, maximum flow-minimum cut, single commodity flow problem, transportation and assignment problems and corresponding solution methodologies;
• Theory, algorithms and analysis of survivability and availability/ reliability in telecommunications networks;
• Routing techniques and traffic flow models: load sharing, alternative routing, adaptive routing, etc;
• Techniques and algorithms for dimensioning of hierarchical networks (single house, multi house, multi service, end-to-end grade of service, etc.); and dimensioning of non-hierarchical networks (dimensioning principles, large-scale dimensioning methods, heuristic for routing optimisation.

This subject will address some advance studies in optimisation theory (linear programming, Simplex algorithm, lagrangian realisation techniques, etc.) and their application in network design problems.

The subject also includes an extensive case study of some challenging multimedia network design problems, e.g.:

• Video on Demand networks;
• Content Distribution Networks;
• MPLS Traffic Engineering and failure recovery in multi service environment under Service Level Agreements;
• Implementation of Spanning Tree Protocol in Ethernet based networks and associated problems.

The topic, also, will include a practical network design project using Linear Programming or other optimisation techniques.

On completion of this subject, the students should have developed some basic skills and knowledge in the intersection of operating research and telegraffic engineering. the main emphasis would be to teach students the art of mathematical modelling and problem solving applicable to some challenging problems in multimedia network design. Some basic objectives are itemised below:

• Basic concepts of graph theory;
• Routing and network flow problems in communication networks;
• Techniques and algorithms for network flow problems;
• Mathematical modelling and optimisation techniques;
• Network dimensioning considering multi-hour, multi-service, survivability and availability/reliability criteria;
• Some advanced technologies in communication networks such as MPLS; Traffic engineering, QoS, CoS, and Differentiated Services analysis.

This subject is not available as a breadth subject.

On completion of this subject, the students should have developed:

• Analytical,critical and creative thinking, with and aptitude for continues self-directed learning;
• Writing, problem solving and communication skills;
• Ability to evaluate and synthesise the research and professional literature;
• Sense of intellectual curiosity;
• Ability to interpret data and research results;
• Sense of intellectual integrity and ethics of scholarship;
• Ability to learn in a range of way, including through information and communication technologies;
• Capacity to confront unfamiliar problems;
• An ability to evaluate and synthesise the research and professional literature;
• Advanced working kills in the application of computer systems and software and a receptiveness to the opportunities offered by new technologies;
• An ability to manage competing demands on time, including self-directed project work.
