With the growing commercial importance of the Internet and the development of new real-time, connection-oriented services like IP-telephony and electronic commerce resilience is becoming a key issue in the design of TP-based networks. Two emerging technologies, which can accomplish the task of efficient information transfer, are Multiprotocol Label Switching (MPLS) and Differentiated Services. A main benefit of MPLS is the ability to introduce traffic-engineering concepts due to its connection-oriented characteristic. With MPLS it is possible to assign different paths for packets through the network. Differentiated services divides traffic into different classes and treat them differently, especially when there is a shortage of network resources. In this thesis, a framework was proposed to integrate the above two technologies and its performance in providing load balancing and improving QoS was evaluated. Simulation and analysis of this framework demonstrated that the combination of MPLS and Differentiated services is a powerful tool for QoS provisioning in IP networks.

President’s Report Hello fellow AITPM members, Welcome to the first edition of the AITPM National Newsletter for 2009! I trust we all had a relaxing break and managed to lose track of all things transport for just a little while. I know I had trouble doing so when hunting for a car space at the shopping centre, and experiencing new projects such as the Tugun Bypass – the new gateway between New South Wales and Queensland. Byron Bay is now as close as Noosa for those high profile beach goers of Brisbane. There was also my experience of the reduced posted speed of 90km/h on the Bruce Highway around the troublesome Gympie stretch, when returning from a short Fraser Coast holiday. I expect that this relatively inexpensive safety improvement will pay substantial dividends in terms of crash reduction. The Newsletter took its annual leave last month and is refreshed and ready for a new year to keep us all informed of the latest in traffic and transport engineering, planning and management. I would like to take this opportunity to acknowledge the ongoing significant contributions of many volunteers in the Newsletter’s production. Mr Andrew Hulse, AITPM’s Immediate Past National President, serves as the Editorial Coordinator on behalf of the Institute. Each Branch Committee also includes a Newsletter Coordinator and committee members frequently contribute as well. And the ongoing contributions of readers enable us to offer the Newsletter as a vehicle for dialogue and debate around our sector. If you would like to contribute please email AITPM’s administration officer Josephine Mitton at aitpm@aitpm.com or through your local Branch Committee. I would also like to welcome back on deck our Editor, Mr David Brown of Driven Media, who creates a fantastic package for us each month. Lastly, members would have received the Call for Papers for the AITPM 2009 National Conference, Traffic Beyond Tomorrow, to be held at the Adelaide Convention Centre between 5 – 7 August. Abstracts will be accepted up to 20 February 2009. We look forward to seeing everyone at this, our flagship event for the year. To all a good year ahead, Jon Bunker Post Script: We all will have seen through the media the enormous scale and nature of the two natural disasters Australia is experiencing at present. AITPM’s thoughts are with all of those members, family and friends who may be experiencing hardship as a result of the Victorian bushfires and North Queensland floods. AITPM is a not for profit organisation however the National Executive has taken the decision to donate in measure to the Red Cross Victorian Bushfire Disaster Relief fund and the Queensland Premier’s Disaster Relief fund as a gesture to support our fellow Australians in their time of need. Details about these funds can be found via the Victorian and Queensland Governments’ websites.
