Recent advances in network bandwidth and processing power have led to the emergence of real time multimedia streaming applications and it is expected that such applications will become an even more dominant source of traffic in future computer networks. Quality of service studies for real-time applications in high-speed networks, point to the importance of the transport layer functionality in admission control, monitoring end-to-end delays, and network bandwidth adaptability. The project will study, design, develop and analyse a comprehensive model for the virtual transport layer to satisfy the necessary quality of service requirements for the next generation of multimedia-based applications.Read moreRead less
Providing End-to-End Quality of Service to Internet Applications. Current Internet only supports limited quality of service (QoS) within isolated domains. This project allows critical applications to be deployed over the global Internet. The project employs a programmable architecture for composing services and intelligent software elements for negotiating acceptable QoS responses for individual application flows over multiple administrative domains. The architecture employs DiffServ's aggregati ....Providing End-to-End Quality of Service to Internet Applications. Current Internet only supports limited quality of service (QoS) within isolated domains. This project allows critical applications to be deployed over the global Internet. The project employs a programmable architecture for composing services and intelligent software elements for negotiating acceptable QoS responses for individual application flows over multiple administrative domains. The architecture employs DiffServ's aggregation property to make it scalable for the Internet core. Successful outcomes would open the floodgates, allowing the development and deployment of applications such as high quality videoconferences, live sport broadcasts, remote medical services, network games, real-time on-line educations, and multimedia distributions.

Fair Intelligent Quality of Service Control and Path Discovery Mechanisms for Internet Scalable Architectures. Until now the Internet only provides best effort service without guaranteeing the timeliness or actual delivery of data. Quality of Service (QoS) architectures have been proposed but not deployed due to a fundamental problem: either the architecture is not scalable or it does not guarantee end-to-end QoS. The project tackles the problem by introducing mechanisms for network path discove ....Fair Intelligent Quality of Service Control and Path Discovery Mechanisms for Internet Scalable Architectures. Until now the Internet only provides best effort service without guaranteeing the timeliness or actual delivery of data. Quality of Service (QoS) architectures have been proposed but not deployed due to a fundamental problem: either the architecture is not scalable or it does not guarantee end-to-end QoS. The project tackles the problem by introducing mechanisms for network path discovery in the network core. The solution allows an integration of both scalability and end-to-end QoS architectures. The outcomes allow network providers to provision network resources efficiently, to develop competitive Internet-based products; and the service providers to develop quality services such as high quality IP phone, multimedia distributions.

PROVISION OF ARBITARY COMPLEX SERVICES ON THE MOBILE INTERNET. Within the next few years, mobile and wireless access to the Internet will very likely become the norm. These networks will use widely different networking technologies. Moreover, the services provided, will be accessed by the users using a wide variety of devices, with significantly different capabilities. Thus to provide seamless access, the system must adapt it self to the operating environment. These adaptations need to occur at ....PROVISION OF ARBITARY COMPLEX SERVICES ON THE MOBILE INTERNET. Within the next few years, mobile and wireless access to the Internet will very likely become the norm. These networks will use widely different networking technologies. Moreover, the services provided, will be accessed by the users using a wide variety of devices, with significantly different capabilities. Thus to provide seamless access, the system must adapt it self to the operating environment. These adaptations need to occur at different levels of the system, in isolation. This project is aimed at investigating the implications of adaptation decisions being taken in isolation at different levels on the system stability and performance.Read moreRead less
High-performance real-time OS framework for low-power applications. Wireless network adapters, as they are being developed by Cisco, will find widespread use in the near future, as they are the basis of all mobile or otherwise disconnected intelligent devices. These devices must process data very rapidly, yet operate with minimal power consumption. We will develop operating system kernels that will support the secure, efficient and protected execution of the core processing firmware, and provide ....High-performance real-time OS framework for low-power applications. Wireless network adapters, as they are being developed by Cisco, will find widespread use in the near future, as they are the basis of all mobile or otherwise disconnected intelligent devices. These devices must process data very rapidly, yet operate with minimal power consumption. We will develop operating system kernels that will support the secure, efficient and protected execution of the core processing firmware, and provide application frameworks for the controlling higher software layers. We will also investigate and design hardware mechanisms that support the software while keeping power consumption minimal.Read moreRead less
Architecture-based Open Network Management Systems for Next Generation Telecommunications. We aim to develop an open, policy-based architecture for the management of next generation telecommunications networks. It is expected that a comprehensive Open Architecture-based Telecommunications Management Network (AuTuMN) framework could be put in place to manage the network based on centralised policies and roles rather than having to handle individual users and elements. Significantly, the scient ....Architecture-based Open Network Management Systems for Next Generation Telecommunications.

Methods that improve the effectiveness of the analysis task would increase the competitiveness of the software industry, and would attract future development work (in complex systems) to Australia. The results of this project will have a direct influence on currently available design tools; the fact that Australian institutions will be (in part) responsible for key theoretical results in this growing field will strengthen Australia's position worldwide as an international centre for computer science.Read moreRead less
