Providing an holistic approach to IMS technologies, IMS: A Development and Deployment Perspective explores service architecture for development and delivery of IMS services.  Approaching IMS from the perspective of the user and the service provider it examines both the current state of deployment and future trends. The book offers a realistic view of IMS deployment to operators and service providers, giving practical examples, application cases and business models. It also presents IMS deployment strategies based on real-life deployment statistics from a live IMS test bed connected to an operator network and proof-of-concept applications including inter-operability trials and results. Focusing on IMS potential in terms of service creation, service composition and service provision the book discusses the ability of IMS to act not only as a service delivery framework, but also as a service integration framework. It presents the possible future of IMS in terms of convergence with Internet services, including discussions about integration with web technologies including the WIMS 2.0 initiative. The book enables a better understanding of how web technologies can complement the IMS service architecture and pioneer the post-IMS progress and success. Presents a novel service-oriented approach to IMS services and applications from a deployment perspective Places IMS in the context of the current telecom environment providing business models through WIMS 2.0 initiativePredicts the trends and potential future for the IMS evolutionProvides a technical foundation to IMS principles and architectureGives examples and solutions to the challenges of service creation and implementation and analyses deployment hurdles and interoperability trialsDescribes trends of convergence based on IMS and Web technologies

Marking the 30th anniversary of the European Conference on Modelling and Simulation (ECMS), this inspirational text/reference reviews significant advances in the field of modelling and simulation, as well as key applications of simulation in other disciplines. The broad-ranging volume presents contributions from a varied selection of distinguished experts chosen from high-impact keynote speakers and best paper winners from the conference, including a Nobel Prize recipient, and the first president of the European Council for Modelling and Simulation (also abbreviated to ECMS). This authoritative book will be of great value to all researchers working in the field of modelling and simulation, in addition to scientists from other disciplines who make use of modelling and simulation approaches in their work.

Itisourgreatpleasuretopresenttheproceedingsofthe15thInternationalConf- ence on Analytical and Stochastic Modelling Techniques and Applications (ASMTA2008)thattookplaceonthebeautifulislandofCyprusforthe?rsttime. The conference has become an important annual event in the ?elds of - alytical modelling and performance evaluation in Europe and internationally. Nevertheless, e?orts have been made year after year to raise the standard and the quality of the programme.This yearthe proceedings are published as partof Springer's prestigiousLecture Notes in Computer Science (LNCS) series. This is another sign of the growing con?dence in the quality standards and procedures followed in the reviewing process and the programme compilation. The conference was honored to have a distinguished keynote speaker in the personofRaymondMariefromIRISA/INRIA,France,whoisaprominent?gure ofthe analyticalmodellingcommunity inEuropeandworldwide.The conference had a high-qualityprogrammewith anacceptanceratio of 40%.The programme comprised 22 high-quality papers organized into 7 sessions. Almost every paper was peer reviewed by three reviewers from the International Programme C- mittee.The reviewers were truly wonderful this year, as well, and in most cases the reviewsprovidedvaluable comments thatcontributedto increasingthe qu- ity of the ?nal versions of the papers. In many cases, discussion panels were also organized when the reviews were not decisive. We would therefore like to give a special thanks to all the members of the International Programme Committee for the excellent work in the reviewing process and the subsequent discussion panels during the selection process.

This book constitutes the refereed proceedings of the 16th International Conference on Analytical and Stochastic Modeling Techniques and Applications, ASMTA 2009, held in Madrid, Spain, in June 2009 in conjunction with ECMS 2009, the 23nd European Conference on Modeling and Simulation. The 27 revised full papers presented were carefully reviewed and selected from 55 submissions. The papers are organized in topical sections on telecommunication networks; wireless & mobile networks; simulation; quueing systems & distributions; queueing & scheduling in telecommunication networks; model checking & process algebra; performance & reliability analysis of various systems.

Itis ourpleasureto presenttheproceedingsofthe17thInternationalConference on Analytical and Stochastic Modelling and Applications (ASMTA 2010). The conferencewasheldintheIconicWalesMillenniumCentreinCardi?,thevibrant capital city of Wales. ASMTA conferences have become established quality events in the calendar of analytical,numerical and even simulation experts in Europe and well beyond. In addition to regular participants from the main centers of expertise from the UK,Belgium,Germany,Russia,France,Italy,Latvia,Spain,Hungaryandmany other countries, we receive newcomers with interesting contributions from other countries such as Algeria, Canada and the USA. Although the conference has become a well-established event, every year ASMTAfeaturessomethingnew.Thisyear,andforthe ?rsttime,the conference was held completely independently and standalone. The decision was not easy as it has always been co-located with the European Conference on Modelling and Simulation. There were some who questioned its chances, but the outcome proved to be excellent. The quality of this year's program was exceptionally high.The conference started with a keynote talk on process algebra by a distinguished speaker in the person of Jane Hillston from the Department of Computer Science of the University of Edinburgh. In addition, 28 papers were accepted for presentation. As ever, the International Program Committee reviewed the submissions cr- ically and in detail, thereby helping in making the ?nal decision and also in providing the authors with useful comments to improve their papers. We would therefore like to thank every member of the International Program Committee for their time and e?orts. We thank everyone for their contribution to ASMTA 2010 and hope readers will enjoy the conference proceedings.

This book constitutes the refereed proceedings of the 18th International Conference on Analytical and Stochastic Modeling Techniques and Applications, ASMTA 2011, held in Venice, Italyin June 2011.The 24 revised full papers presented were carefully reviewed and selected from many submissions.The papers are organized in topical sections on queueing theory, software and computer systems, statistics and inference, telecommunication networks, and performance and performability.
