The demands made of modern high-speed data networks, such as those that make up the Internet, are increasing rapidly in terms of both the quantity and quality of service required.
So that these demands can be satisfied, it is necessary that network operators, or even the network itself, take measurements and make control decisions. Depending on the service, there is a need to do this over very short timescales (fractions of a second), or longer
timescales (minutes or even weeks).
By developing innovative mathematical models of network behaviour,
this project will deliver improved methods for measurement and
control of the Internet.Read moreRead less

Optical-OFDM provides Australia with an opportunity to develop a new, high-tech, easy-to-export technology with a very large market potential spanning three key communications markets: wireless personal-area networks, local-area networks and long-haul (80-4000 km) optical networks. It is based on innovative Australian technology generated from two research strengths: photonics and OFDM. OFDM is already the basis of most non-optical broadband systems, including digital broadcasting and ADSL. Patent applications have been filed. One application enables bandwidths to rural and remote communities to be quadrupled without laying new cables. By launching off this local market Australian industry can develop a world leading industry.Read moreRead less

The project aims to develop new bandwidth-efficient index coding schemes to reduce network congestion. A large portion of the increasing internet traffic is due to video content browsing and distribution. This creates serious strains on the current network infrastructure, which is designed to support conventional data.
