* Provides case studies in each chapter illustrating how principles work in practice. * Compares strengths and weaknesses of off-the-shelf software packages.

The modern application server is a complex platform that is the linchpin of an enterprise environment that includes a very wide range of technologies-web document formatting, web protocols, server-side scripts, servlets, applets, programming languages, distributed object technologies, security capabilities, directory and naming services, load balan

Computational Science is the scientific discipline that aims at the development and understanding of new computational methods and techniques to model and simulate complex systems. The area of application includes natural systems - such as biology environ mental and geo-sciences, physics, and chemistry - and synthetic systems such as electronics and financial and economic systems. The discipline is a bridge bet ween 'classical' computer science - logic, complexity, architecture, algorithm- mathematics, and the use of computers in the aforementioned areas. The relevance for society stems from the numerous challenges that exist in the various science and engineering disciplines, which can be tackled by advances made in this field. For instance new models and methods to study environmental issues like the quality of air, water, and soil, and weather and climate predictions through simulations, as well as the simulation-supported development of cars, airplanes, and medical and transport systems etc. Paraphrasing R. Kenway (R.D. Kenway, Contemporary Physics. 1994): 'There is an important message to scientists, politicians, and industrialists: in the future science, the best industrial design and manufacture, the greatest medical progress, and the most accurate environmental monitoring and forecasting will be done by countries that most rapidly exploit the full potential of computational science'. Nowadays we have access to high-end computer architectures and a large range of computing environments, mainly as a consequence of the enormous sti mulus from the various international programs on advanced computing, e.g.

This book is a result of the ISD'99, Eight International Conference on Infonnation Systems Development-Methods and Tools, Theory, and Practice held August 11-13, 1999 in Boise, Idaho, USA. The purpose of this conference was to address the issues facing academia and industry when specifying, developing, managing, and improving infonnation systems. ISD'99 consisted not only of the technical program represented in these Proceedings, but also of plenary sessions on product support and content management systems for the Internet environment, workshop on a new paradigm for successful acquisition of infonnation systems, and a panel discussion on current pedagogical issues in systems analysis and design. The selection of papers for ISD'99 was carried out by the International Program Committee. Papers presented during the conference and printed in this volume have been selected from submissions after fonnal double-blind reviewing process and have been revised by their authors based on the recommendations of reviewers. Papers were judged according to their originality, relevance, and presentation quality. All papers were judged purely on their own merits, independently of other submissions. We would like to thank the authors of papers accepted for ISD'99 who all made gallant efforts to provide us with electronic copies of their manuscripts confonning to common guidelines. We thank them for thoughtfully responding to reviewers comments and carefully preparing their final contributions. We thank Daryl Jones, provost of Boise State University and William Lathen, dean, College of Business and Economics, for their support and encouragement.

Welcome to MMNS 2003. Multimedia services over IP networks are proliferating at an enormous speed. There is also increasing demand for solutions that provide assured levels of s- vice quality. All of these require novel paradigms, models, and architectures for realizing integrated end-to-end service management rather than managing n- work elements in isolation. Providing scalable Quality of Service (QoS) while maintaining fairness, along with secure and optimal network resource mana- ment, are key challenges for the future Internet. These challenges apply to both ?xed and wireless networks. This book contains all of the papers presented at the 6th IFIP/IEEE - ternational Conference on Management of Multimedia Networks and Services (MMNS 2003) hosted by The Queen’s University of Belfast, Northern Ireland, September 7–10, 2003. MMNS 2003 follows the successful conferences held in Santa Barbara (2002), Chicago (2001), Fortaleza, Brazil (2000), Paris (1998), and Montreal (1997). MMNS uses single-track presentations, which provide an intimate setting for discussion and debate. The conference is known for its high quality papers from various research communities. In just six years, MMNS has established itself as one of the premier conferences focusing on the management of multimedia networks and services. The conference objective is to bring - gether researchers working in all facets of network and service management as applied to broadband networks and multimedia services.
