Modelling, Measurement and Control of the Internet. 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 lon ....Modelling, Measurement and Control of the Internet. 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
Increasing internet energy and cost efficiency by improving higher-layer protocols. Australians rely heavily on our telecommunications infrastructure due to our geographic dispersion. We are also very susceptible to climate change, given our reliance on agriculture. Information technology is consuming a rapidly increasing fraction of our power and our budget. This research will help to reverse both those trends, by finding novel and practical ways to use our infrastructure more efficiently, and ....Increasing internet energy and cost efficiency by improving higher-layer protocols. Australians rely heavily on our telecommunications infrastructure due to our geographic dispersion. We are also very susceptible to climate change, given our reliance on agriculture. Information technology is consuming a rapidly increasing fraction of our power and our budget. This research will help to reverse both those trends, by finding novel and practical ways to use our infrastructure more efficiently, and to minimise its energy use. This will enable the Australian telecommunications industry to provide better service (including to Australian industries and rural communities) at lower economic and environmental cost. This project will put Australia on the international stage as a leading contributor to energy-efficient internet technology.Read moreRead less
High Performance Firewalls for Network Security. This project aims to improve the accuracy and efficiency of firewall systems for defending the security of large networks.

Our industry partner, IntelliGuard, is developing a parallel system architecture for firewalls, which will provide sufficient processing capacity to support more sophisticated traffic analysis in high speed networks. Our aim is to develop parallel algorithms for traffic analysis and load balancing that can exploit the capacity of these new firewalls. This project provides an excellent opportunity for an Australian company to compete in the growing security market.Read moreRead less
Defending Against Attacks on Internet-Based Telephone Services (Voice Over IP). The telephone network is a critical platform for communication, used by all levels of society - government, the private sector and the general public. The shift to telephone services based on voice-over-IP technology holds the promise of significantly reducing costs for communication services. However, the Internet has long been plagued by a variety of network attacks.

The telephone network is a critical platform for communication, used by all levels of society - government, the private sector and the general public. The shift to telephone services based on voice-over-IP technology holds the promise of significantly reducing costs for communication services. However, the Internet has long been plagued by a variety of network attacks. Reports of denial-of-service attacks, viruses and break-in attempts frequently appear in the world news. A major impediment to confidence in voice-over-IP services is the risk of attacks on its infrastructure, and the potential for using weaknesses in voice-over-IP infrastructure to launch attacks on the existing telephone network.Read moreRead less
Robust next-generation detection techniques to defend operational networks against attacks. As networks are fast becoming one of the pillars of our society, network security is essential.
Without good security, networks will be unreliable, more costly, and restricted in the capabilities they can offer. The project will allow advanced anomaly and intrusion detection techniques to be used in the ultra-high speeds of the Internet core. It will provide the groundwork for the attack detection and p ....Robust next-generation detection techniques to defend operational networks against attacks.

Carrier-scale defence against distributed denial-of-service attacks. Distributed Denial-of-Service (DDoS) attacks are one of the most persistent and damaging threats to services on the Internet. In recent years, there has been widespread use of DDoS attacks for both financial and political advantage by attackers. The challenge for our Australian industry partner (PowerGuard Pty Ltd) is to continue to scale their DDoS defence platform so that it can be used in much higher bandwidth environments, ....Carrier-scale defence against distributed denial-of-service attacks. Distributed Denial-of-Service (DDoS) attacks are one of the most persistent and damaging threats to services on the Internet. In recent years, there has been widespread use of DDoS attacks for both financial and political advantage by attackers. The challenge for our Australian industry partner (PowerGuard Pty Ltd) is to continue to scale their DDoS defence platform so that it can be used in much higher bandwidth environments, such as carriers’ backbone networks, or large government and commercial networks that have multiple high-speed links to the Internet. The results of this project will provide an Australian company with a leading position in this important and growing market. Read moreRead less

Mechanism design for next generation random access wireless protocols. Australia is well placed to take the lead in replacing carbon-intensive travel by teleconferencing, because of its isolation and geographic dispersion. Because these large distances introduce inevitable delays, it is important that the network itself add as little delay as possible for such real-time services.
