Carrier Ip Telephony 2000

Extensively examining IP telephony from the service provider's perspective, this book addresses the problems and possibilities associated with the future of telecom transport. Answering the crucial questionHow can established and emerging carriers leverage IP-telephony service?, this report presents a valuable compilation of the latest research and most provocative insight from a broad range of industry professionals. Here, service providers will find in-depth analysis of the issues that must be resolved before IP telephony can achieve carrier-class status.

The Practical Handbook of Internet Computing analyzes a broad array of technologies and concerns related to the Internet, including corporate intranets. Fresh and insightful articles by recognized experts address the key challenges facing Internet users, designers, integrators, and policymakers. In addition to discussing major applications, it also covers the architectures, enabling technologies, software utilities, and engineering techniques that are necessary to conduct distributed computing and take advantage of Web-based services. The Handbook provides practical advice based upon experience, standards, and theory. It examines all aspects of Internet computing in wide-area and enterprise settings, ranging from innovative applications to systems and utilities, enabling technologies, and engineering and management. Content includes articles that explore the components that make Internet computing work, including storage, servers, and other systems and utilities. Additional articles examine the technologies and structures that support the Internet, such as directory services, agents, and policies. The volume also discusses the multidimensional aspects of Internet applications, including mobility, collaboration, and pervasive computing. It concludes with an examination of the Internet as a holistic entity, with considerations of privacy and law combined with technical content.

The Internet revolution. Once, the public was delighted with 14.4 modem access and fascinated by low-tech Web site content. But not for long. Technology has raced to keep up with users' calls for high-speed facilities and advanced applications. With the development of high-speed transmission media and the availability of high-speed hardware, we are

Constraint satisfaction and constraint programming have shown to be very simple but powerful ideas, with applications in various areas. Still, in the last ten years, the simple notion of constraints has shown some deficiencies concerning both theory and practice, typically in the way over-constrained problems and preferences are treated. For this reason, the notion of soft constraints has been introduced with semiring-based soft constraints and valued constraints being the two main general frameworks. This book includes formal definitions and properties of semiring-based soft constraints, as well as their use within constraint logic programming and concurrent constraint programming. Moreover, the author shows how to adapt existing notions and techniques such as abstraction and interchangeability to the soft constraint framework and it is demonstrated how soft constraints can be used in some application areas, such as security. Overall, this book is a great starting point for anyone interested in understanding the basics of semiring-based soft constraints.

ETAPS2002wasthe?fthinstanceoftheEuropeanJointConferencesonTheory and Practice of Software. ETAPS is an annual federated conference that was established in 1998 by combining a number of existing and new conferences. This year it comprised 5 conferences (FOSSACS, FASE, ESOP, CC, TACAS), 13 satellite workshops (ACL2, AGT, CMCS, COCV, DCC, INT, LDTA, SC, SFEDL, SLAP, SPIN, TPTS, and VISS), 8 invited lectures (not including those speci?c to the satellite events), and several tutorials. The events that comprise ETAPS address various aspects of the system - velopmentprocess,includingspeci?cation,design,implementation,analysis,and improvement. The languages, methodologies, and tools which support these - tivities are all well within its scope. Di?erent blends of theory and practice are represented, with an inclination towards theory with a practical motivation on one hand and soundly-based practice on the other. Many of the issues involved in software design apply to systems in general, including hardware systems, and the emphasis on software is not intended to be exclusive.
