The present information age is enabled by telecommunications and information technology and the continued convergence of their services, technologies and business models. Within telecommunications, the historic separations between fixed networks, mobile telephone networks and data communications are diminishing. Similarly, information technology and enterprise communications show convergence with telecommunications. These synergies are captured in the concept of Next Generation Networks that result from evolution to new technologies, enabling new services and applications. Network Convergence creates a framework to aid the understanding of Next Generation Networks, their potential for supporting new and enhanced applications and their relationships with legacy networks. The book identifies and explains the concepts and principles underlying standards for networks, services and applications. Network Convergence: Gives comprehensive coverage of packet multimedia, enterprise networks, third generation mobile communications, OSA/Parlay and developments in fixed networks. Gives an integrated view of diverse information and communications systems and technology through a common NGN Framework. Delves into protocols, APIs and software processes for supporting services and applications in advanced networks. Discusses a variety of applications of telecommunications supporting IT and IT enhanced by communications. Follows developments in operations support systems standards and links these to next generation networks. Includes a wealth of examples, use cases, tables and illustrations that help reinforce the material for students and practitioners. Features an accompanying website with PowerPoint presentations, glossary, web references, tutorial problems, and 'learn more' pages. This essential reference guide will prove invaluable to advanced undergraduate and graduate students, academics and researchers. It will also be of interest to professionals working for telecommunications network operators, equipment vendors, telecoms regulators, and engineers who wish to further their knowledge of next generation networks.

This practical guide shows how to facilitate collaboration among diverse individuals and organizations to navigate complexity and create change in our interconnected world. The social and environmental challenges we face today are not only complex, they are also systemic and structural and have no obvious solutions. They require diverse combinations of people, organizations, and sectors to coordinate actions and work together even when the way forward is unclear. Even so, collaborative efforts often fail because they attempt to navigate complexity with traditional strategic plans, created by hierarchies that ignore the way people naturally connect. By embracing a living-systems approach to organizing, impact networks bring people together to build relationships across boundaries; leverage the existing work, skills, and motivations of the group; and make progress amid unpredictable and ever-changing conditions. As a powerful and flexible organizing system that can span regions, organizations, and silos of all kinds, impact networks underlie some of the most impressive and large-scale efforts to create change across the globe. David Ehrlichman draws on his experience as a network builder; interviews with dozens of network leaders; and insights from the fields of network science, community building, and systems thinking to provide a clear process for creating and developing impact networks. Given the increasing complexity of our society and the issues we face, our ability to form, grow, and work through networks has never been more essential.

A much-needed guide through the thicket of conflicting IP telephony technologies.-Scott Bradner Convergence of the Internet and the Public Switched Telephone Network (PSTN) makes possible a wide range of new telecommunications services. Written by the industry leaders at Bell Laboratories, this book puts the future of convergence in perspective and helps you make decisions that leverage its power. The authors describe the network infrastructure, then explain how the PSTN and Internet are being modified to work with each other. They also define and explore three aspects of the convergence: 1) interworking with VoIP, 2) IP-based service control, and 3) remote access to IP networks. With this book, you'll get an insider's perspective of key technologies, an in-depth review of the relevant standards, and a detailed survey of emerging applications and products.You'll also learn how to determine which products and services are right for your organization. Wiley Networking Council Books put technology into perspective for decision-makers who need an implementation strategy, a vendor and outsourcing strategy, and a product and design strategy. The Council of series advisors is composed of three of the the most influential leaders of the networking community:Visit our Web site at www.wiley.com/compbooks/ Visit the Networking Council Web site at www.wiley.com/networking council

Covers the latest standards and those being developed in an ever-evolving field Provides insight into the latest technology of video and data over wireless networks and how convergence will be a driving force in this industry Provides an understanding of the true capabilities behind each vendor's solution to allow for informed buying decisions A recent survey of 500 U.S. companies with multiple locations found that 81% are planning to implement IP Telephony on their local area networks (LANs) in 2003, and two-thirds are looking at convergence for their wide area networks (WANs) as well. This includes voice, video and data over hard line and wireless networks. Today, new standards and technologies are being developed to support convergence and voice over IP (VoIP) and Video over IP and wireless. Because convergence covers the voice and data world, it will be critical to understand all of these environments. Voice, Video, and Data Network Convergence provides detailed information on convergence network models, protocol stacks, routing algorithms, gateways and switches required to support these networks. Covers the latest standards and those being developed in an ever-evolving field Provides insight into the latest technology of video and data over wireless networks and how convergence will be a driving force in this industry Provides an understanding of the true capabilities behind each vendor's solution to allow for informed buying decisions

This book focuses largely on enabling technologies for network convergence. A principal aim is to show where parallel functions exist in fixed and mobile voice network architectures and to explain how these functions will be combined. The authors describe the components of a future converged architecture and consider the following key aspects: QoS Requirements, Proposed Solution Architectures, Protocol and Interface options, Underlying Network Issues and Security issues. The book also compares and describes initiatives from several standards bodies working to simplify to a clean architecture and a common set of protocols. The impact on a Multi Protocol Label Switching (MPLS) network, the preferred method of transport for the core network, will be considered in detail.

This book will serve as a link between academia and industry, serving students, researchers, and industry professionals.

Service-oriented architecture (SOA) uses services as the baseline for developing new architectures and applications, as networks are built specifically to satisfy service requirements. Most services are currently handled over different networks, but newer services will soon require cross-network support. Architecting the Telecommunication Evolution
