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.

Resilience Oriented Multicast for Real-time Multimedia. The current communication infrastructure market is one of the largest market segments in the world. However, it is evident that the current Internet provides limited support for a multitude of current, emerging and future services that require multicasting support (worldwide, enhanced IP service revenues are forecast to grow to $104.4 billion in 2005).

The current communication infrastructure market is one of the largest market segments in the world. However, it is evident that the current Internet provides limited support for a multitude of current, emerging and future services that require multicasting support (worldwide, enhanced IP service revenues are forecast to grow to $104.4 billion in 2005). The introduction of enhanced multicasting services will result in lowered input costs to industries and consumers with a wider choice of enhanced services. The mechanisms developed in this project will allow service providers to raise additional revenue and differentiate themselves by offering a wide range of enhanced services.Read moreRead less

The revenue generated from traditional telecommunication services is continuing to drop. New value-added services such as multimedia services become the fastest growing revenue-generating sector in Australia's telecommunications industry. The ubiquitous presence of scaling behaviour in network traffic presents a big challenge for delivering better Quality-of-Service (QoS) which is demanded by the new services. A complete understanding of the scaling behaviour and its impact is very important. This research addresses a key problem of defining the timescale range of interest for the scaling behaviour. The research outcome benefits a number of areas, which are all critical for developing enhanced QoS support and better network management.Read moreRead less
