Title An Holistic View of Quality of Service
Output type: Journal article
Journal title: Interactive Learning Environments
Month/year of publication: April 2001
Pagination: 33-50
Volume: 9 (1)
ISSN: 1744-5191
DOI: 10.1076/ilee.9.1.33.3575 ?
Research group: B - Networking and Distributed Systems
Co-authors: Lawson, H., McKechan, D., Ruddle, A.
Other relevant details: Significance: The significance of the approach developed here places the user, rather than the network interface card or operating system, at the centre of QoS analysis. Originality: The originality of the work is in the breadth of perspective in analysing the users experience of a network based application, ranging from interactive delay to page layout accessibility. Rigour: The rigour of the analysis is based on feedback from evaluations carried out with real users using real applications.

Title Modelling the evolution of legacy systems to Web-based systems
Output type: Journal article
Journal title: Journal of Software Maintenance and Evolution: Research and Practice
Month/year of publication: January 2004
Pagination: 5-30
Volume: 16 (1-2)
ISSN: 1532-0618
DOI: 10.1002/smr.282 ?
Research group: B - Networking and Distributed Systems
Co-authors: Boldyreff, C., Lavery, J., Ling, B.
Other relevant details: Significance: The significance of this work is that the problem it addresses is still in clear evidence in most institutional information systems. The problems of migrating heavily used "legacy" installed information systems to user-oriented web-based delivery is described with reference to case studies of student record management systems at two disparate Universities. Originality: An original approach of "analyse, model, improve" is demonstrated to provide an effective framework for software evolution in this context. Rigour: The rigour is derived from the application of a common analytical framework at the two very different institutions.

Title Services, Semantics and Standards: Elements of a Learning Grid Infrastructure
Output type: Journal article
Journal title: Applied Artificial Intelligence
Month/year of publication: November 2005
Pagination: 861-879
Volume: 19 (9-10)
ISSN: 1087-6545
DOI: 10.1080/08839510500234271 ?
Research group: B - Networking and Distributed Systems
Co-authors: Cerri, S. A., Gaeta, A., Ritrovato, P
Number of additional co-authors: 1
Other relevant details: Significance: The significance lies in the bringing together of the three themes to enable a radical advance in technology enhanced learning concepts and systems. Originality: The originality lies in the comparison between product-based learning and service-based learning and how the latter is demonstrably superior. Rigour: Rigour is shown by identifying the limitations caused by the implicit product-based philosophy in existing standards and specifications for technology enhanced learning. The impact of this work can be found in the explicit reference to Grid service based approaches in the 2nd ESRC/EPSRC call for technology enhanced learning proposals in the Teaching and Learning Research Program.

Title Responsiveness on the Interactive Grid
Output type: Conference contribution
Conference: IEEE International Conference on Communications 2007, (ICC '07), Glasgow, 24-28 June
Month/year of publication: 01/06/2007
Number of pages: 6
Media of output:
ISSN: 1-4244-0353-7
DOI: 10.1109/ICC.2007.68 ?
Research group: B - Networking and Distributed Systems
Co-authors: Miller, A., Purdie, S.
Other relevant details: Significance: The analytical model was first devised and used in 1997 to better understand latency on the web, so the historical chain of its usage reflects the changes in the technologies associated with, and the philosophies behind, network service deployments over the last decade, from Web to Grid. Originality: The originality of this current analysis lies in the design and application of a QoS framework for interactive (as opposed to batch) Grids. Rigour: The experiments and measurements were all carried out on real networks, systems and applications, using PlanetLab nodes to establish a baseline for normal Internet delay.
