Organisations are increasingly concerned with the effective utilisation of Web technologies, and especially the ways in which these technologies can be used to improve their business. Effective management of knowledge about the interplay between the organisation and technical drivers of this technology adoption will enable a much-enhanced process for leveraging emerging information and communication technologies. This project aims to link related research at UTS and Southampton University to understand how tools might support this knowledge management. Outcomes will include the creation of specific tools (and techniques for using them) within the context of managing organisational uptake of new technologies.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
Building correct-by-construction distributed systems from specifications stating how agents' knowledge evolves over time. Many distributed computer system implementations fail to comply with their original informal requirement specification. These requirements typically refer to the migration of information through the system over time, but current specification languages are not rich enough to express such requirements on a sufficiently abstract level. This results in a huge error-provoking gap ....Building correct-by-construction distributed systems from specifications stating how agents' knowledge evolves over time. Many distributed computer system implementations fail to comply with their original informal requirement specification. These requirements typically refer to the migration of information through the system over time, but current specification languages are not rich enough to express such requirements on a sufficiently abstract level. This results in a huge error-provoking gap between the informal requirements and the starting point of formally verifiable development. To minimise this gap, we develop a particularly expressive specification language, a calculus for stepwise refinement from such specifications down to distributed systems, and an automated tool for checking and supporting refinement steps in the calculus.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
