The DSL arena is expanding rapidly, making it highly unlikely that any single author can adequately address the breadth and depth of the subject. Responding to the demand of designers worldwide, Fundamentals of DSL Technology combines the strengths of the field's most renowned DSL experts, providing a foundation of all aspects of DSL system design. The volume begins with an introductory three-chapter examination of DSL copper transmission channels, reviewing the basic telephone environment, the physical-layer twisted pair, and the noise environment in the twisted pair channel. The book then explores line codes - laying the foundation for later chapters about other aspects of DSL design - and discusses the basic objectives of DSL service, comparing DSL to other broadband delivery methods. The book concludes with a description of other basic aspects of DSL transmission, covering topics such as trellis codes, Reed-Solomon codes and interleaving, turbo and LDPC codes, basic equalization theory, synchronization, and more.

A comparative guide to the technologies, capabilities, and costs of next-generation desktop connectivity With the advent of cable modems and Digital Subscriber Lines (DSLs), modem technology has entered a new and highly sophisticated realm that is light-years beyond PC modems. Integrating and interoperating at high transmission levels with telephone and cable broadcast infrastructure to allow for faster, clearer transmission of data-intensive Web pages, DSLs and cable modems are competing for attention in this massive emerging market. For network managers, LAN administrators, and corporate planners charged with purchasing, installing, and troubleshooting last-mile technology for their organizations, Gilbert Held details what you'll need to know to make informed choices for the future. Offering simple explanations and in-depth comparisons, this book considers the whole range of strategic, technical, and investment concerns, from cost analysis and bandwidth limitations to suitability for various business and residential applications. Held discusses why a new generation of modems is needed and why those modems require a different infrastructure from those that transmit data over the PSTN. The fundamentals of DSLs are presented along with a look at how cable modems operate. And a comprehensive comparison of DSL and cable modem technology is provided that covers their advantages and disadvantages as well as their potential use for business and residential subscribers. This book contains everything you'll need to know about next- generation modems including: * Information on how infrastructure and content variables map to Web wait time * Transmission fundamentals for current modem operations * Discussions on how different types of DSLs overcome bandwidth limitations * A survey of the DSL family * A tutorial in the cable TV infrastructure * Coverage of the cable modem standard * Comparative analysis of costs, throughput, and suitability for various applications

The definitive resource on domain-specific languages: based on years of real-world experience, relying on modern language workbenches and full of examples. Domain-Specific Languages are programming languages specialized for a particular application domain. By incorporating knowledge about that domain, DSLs can lead to more concise and more analyzable programs, better code quality and increased development speed. This book provides a thorough introduction to DSL, relying on today's state of the art language workbenches. The book has four parts: introduction, DSL design, DSL implementation as well as the role of DSLs in various aspects of software engineering. Part I Introduction: This part introduces DSLs in general and discusses their advantages and drawbacks. It also defines important terms and concepts and introduces the case studies used in the most of the remainder of the book. Part II DSL Design: This part discusses the design of DSLs - independent of implementation techniques. It reviews seven design dimensions, explains a number of reusable language paradigms and points out a number of process-related issues. Part III DSL Implementation: This part provides details about the implementation of DSLs with lots of code. It uses three state-of-the-art but quite different language workbenches: JetBrains MPS, Eclipse Xtext and TU Delft's Spoofax. Part IV DSLs and Software Engineering: This part discusses the use of DSLs for requirements, architecture, implementation and product line engineering, as well as their roles as a developer utility and for implementing business logic. The book is available as a printed version (the one your are looking at) and as a PDF. For details see the book's companion website at http: //dslbook.org

This is a concise presentation of the concepts underlying the design of digital communication systems, without the detail that can overwhelm students. Many examples, from the basic to the cutting-edge, show how the theory is used in the design of modern systems and the relevance of this theory will motivate students. The theory is supported by practical algorithms so that the student can perform computations and simulations. Leading edge topics in coding and wireless communication make this an ideal text for students taking just one course on the subject. Fundamentals of Digital Communications has coverage of turbo and LDPC codes in sufficient detail and clarity to enable hands-on implementation and performance evaluation, as well as 'just enough' information theory to enable computation of performance benchmarks to compare them against. Other unique features include space-time communication and geometric insights into noncoherent communication and equalization.

Grid computing is an emerging technology designed for high-powered applications. Grid Application Systems Design shows how to unleash the high performance of Grid technology. It begins by delving into the history and theory of grid computing, providing background on the concepts, terminology, and issues surrounding it. The book then examine

Extending beyond the technical architecture to the very philosophy of how a business should operate, the Service Orientation approach establishes fluidity across boundaries to provide agility, transparency, and fundamental competitive advantage. Service Oriented Enterprises brings the concept of service orientation from the IT department to the boardroom, applying the precepts of service oriented technology to the underlying dynamics of how a business operates. Implementing a technological concept as a cultural paradigm, the SOE succeeds by combining the best features from virtual, extended, real-time, and resilient enterprises to serve not just its customers, but also its trading partners, shareholders and employees. Building primarily on the success of the Internet and the automation of business policies and processes, the Service Oriented Enterprise (SOE) is defined by three essential layers: the enterprise performance layer, the business process management layer, and the underlying service oriented architecture. This book focuses primarily on layers two and three and how the fundamental dynamics of a business can be altered when these concepts are applied to both architecture and culture. Beginning with an overview of the emerging SOE culture, the text contrasts the new service-oriented methodologies with traditional waterfall and iterative methodologies. Emphasizing Web Service strategies for description, discovery, and deployment techniques, the author goes deeper into service-oriented concepts describing the business process management suite as the central core of the SOE, and introducing the Enterprise Service Bus as the backbone for integration. The text describe how modeling, executing, and continuously improving the business process and business policies lends to the development of a common language between business and IT. The book concludes by expanding on these concepts and delving into the societal and behavioral aspects of the Service Oriented Enterprise. The reality of business is no longer one where change is an unusual phenomenon; today change is the norm and the capacity for consumer-sensitive, fluid transition is vital to business survival. Service Oriented Enterprises provides the key concepts to facilitate that change.
