Service and Device Discovery is a complete survey of the state-of-the-art in an emerging field. Client/server architectures may not be new, but the world has changed around them. Increasingly complex networked environments and the proliferation of mobile devices create many instances where highly dynamic client/service behavior is the norm and not the exception. Service discovery protocols enable plug and play architectures, where services may be introduced into a network and removed at will, without configuration hassles. In addition, service discovery is an important step toward eliminating manually installed drivers, relying instead on standard interfaces to put devices in touch.

WHY SERVICE DISCOVERY?

Service discovery will make networked devices significantly less tedious to deploy and use than they are today. As a way to standardize the environments in which client/server applications are developed and used, service discovery technologies have the potential to:
* make interactions between clients and services much more dynamic
* provide software tools for developing machine-to-machine communications
* automate discovery of required services and peripherals
* reduce administrative overhead for deploying or interfacing services
* minimize re-configuration and encourage more device mobility
* build more interesting applications for networked environments

INSIDE THE SERVICE DISCOVERY FRAMEWORK, designers and programmers will learn how clients can discover needed services. How services advertise their presence. How catalogs track available services and garbage collection facilities rid the system of outdated information. How multicast is used to support discovery and advertisement. How to enable clients to browse and subtype services. And how to anticipate interoperability issues.

In this book, researcher and developer Golden G. Richard III:
* Condenses thousands of pages of protocol specifications to their essentials and helps you interpret predictably terse material
* Investigates all four leading protocols for service discovery
* Provides complete client and service examples in Java and C

Service and Device Discovery: Protocols and Programming contains fully documented source code for representative clients and services, for all four technologies, examined and explained in detail.

Since the beginning of the 1980s, configuration software has developed and evolved. It should be said that configuration software, as a kind of application software, rose with the development of personal computers. The development of configuration software is closely related to the development of the industrial control system. With the rapid development of modern industries, the production process continues to expand in scale, and its complexity is increasing. The process of industrial production is now being transformed from labour intensive, equipment intensive, and information intensive to a more knowledge intensive fashion. Configuration software as a product appeared in the early 80s, and was widely used in the late 80s. But before the mid-90s, the configuration software application was not universal. With the applications of industrial control systems widely used around the world, in the face of larger and more complex control systems, users have become gradually more aware of original host computer programming. This mode is time-consuming. The loss outweighs the gains. At the same time, MIS (management information systems) and CIMS (computer integrated manufacturing systems), and a large number of applications require an industrial site for enterprise production, management, and decision-making to provide more detailed and in-depth data in order to optimize the production and operation of enterprises in all aspects.

This book provides comprehensive research on the communication performance of a real time industrial fieldbus.

Groundbreaking Patterns for Building Simpler, More Powerful Networks In "Patterns in Network Architecture," pioneer John Day takes a unique approach to solving the problem of network architecture. Piercing the fog of history, he bridges the gap between our experience from the original ARPANET and today's Internet to a new perspective on networking. Along the way, he shows how socioeconomic forces derailed progress and led to the current crisis. Beginning with the seven fundamental, and still unanswered, questions identified during the ARPANET's development, "Patterns in Network Architecture" returns to bedrock and traces our experience both good and bad. Along the way, he uncovers overlooked patterns in protocols that simplify design and implementation and resolves the classic conflict between connection and connectionless while retaining the best of both. He finds deep new insights into the core challenges of naming and addressing, along with results from upper-layer architecture. All of this in Day's deft hands comes together in a tour de force of elegance and simplicity with the annoying turn of events that the answer has been staring us in the face: Operating systems tell us even more about networking than we thought. The result is, in essence, the first "unified theory of networking," and leads to a simpler, more powerful--and above all--more scalable network infrastructure. The book then lays the groundwork for how to exploit the result in the design, development, and management as we move beyond the limitations of the Internet. Using this new model, Day shows how many complex mechanisms in the Internet today (multihoming, mobility, and multicast) are, with this collapse in complexity, now simply a consequence of the structure. The problems of router table growth of such concern today disappear. The inescapable conclusion is that the Internet is an unfinished demo, more in the tradition of DOS than Unix, that has been living on Moore's Law and 30 years of band-aids. It is long past time to get networking back on track. - Patterns in network protocols that synthesize "contradictory" approaches and simplify design and implementation- "Deriving" that networking is interprocess communication (IPC) yielding- A distributed IPC model that repeats with different scope and range of operation- Making network addresses topological makes routing purely a local matter- That in fact, private addresses are the norm--not the exception--with the consequence that the global public addresses required today are unnecessary- That mobility is dynamic multihoming and unicast is a subset of multicast, but multicast devolves into unicast and facilitates mobility- That the Internet today is more like DOS, but what we need should be more like Unix- For networking researchers, architects, designers, engineers Provocative, elegant, and profound, "Patterns in Network Architecture" transforms the way you envision, architect, and implement networks.

A groundbreaking study of one of the most crucial yet least understood issues of the twenty-first century: the governance of the Internet and its content The Internet has transformed the manner in which information is exchanged and business is conducted, arguably more than any other communication development in the past century. Despite its wide reach and powerful global influence, it is a medium uncontrolled by any one centralized system, organization, or governing body, a reality that has given rise to all manner of free-speech issues and cybersecurity concerns. The conflicts surrounding Internet governance are the new spaces where political and economic power is unfolding in the twenty-first century. This all-important study by Laura DeNardis reveals the inner power structure already in place within the architectures and institutions of Internet governance. It provides a theoretical framework for Internet governance that takes into account the privatization of global power as well as the role of sovereign nations and international treaties. In addition, DeNardis explores what is at stake in open global controversies and stresses the responsibility of the public to actively engage in these debates, because Internet governance will ultimately determine Internet freedom.

Durant la ultima decada, la versio actual de la tecnologia central d'Internet s'esta completant gradualment per una versio mes recent, IPv6 o "IP versio 6." S'esta comencant relativament lentament, pero es pot preveure que anira guanyant velocitat a mesura que mes i mes usuaris i proveidors de serveis es trobin obligats a fer el canvi, entre altres pel futur exhauriment de les adreces actuals. Malauradament, tambe hem de constatar que una gran part dels usuaris a penes n'hem sentit parlar. En aquest text es vol presentar una visio damunt de tot realista i divulgativa d'IPv6. S'hi intenta presentar l'estat de la questio, pero sempre des de la vessant practica i directament aplicable. Tracta aspectes com: que es IPv6? Com ens hi podem connectar? Quins canvis ens representa a nivell organitzatiu de les xarxes que fem servir cada dia? Ho notarem molt? Tambe es comenten quins avantatges i quins possibles inconvenients hi podem trobar, tant avui que estarem en una situacio de transicio entre IPv4 i IPv6, com en el futur moment en que es de preveure tan sols subsistira IPv6.

In recent years, a considerable amount of effort has been devoted, both in industry and academia, towards the design, performance analysis and evaluation of modulation schemes to be used in wireless and optical networks, towards the development of the next and future generations of mobile cellular communication systems. Modulation Theory is intended to serve as a complementary textbook for courses dealing with Modulation Theory or Communication Systems, but also as a professional book, for engineers who need to update their knowledge in the communications area. The modulation aspects presented in the book use modern concepts of stochastic processes, such as autocorrelation and power spectrum density, which are novel for undergraduate texts or professional books, and provides a general approach for the theory, with real life results, applied to professional design. This text is suitable for the undergraduate as well as the initial graduate levels of Electrical Engineering courses, and is useful for the professional who wants to review or get acquainted with the a modern exposition of the modulation theory. The book covers signal representations for most known waveforms, Fourier analysis, and presents an introduction to Fourier transform and signal spectrum, including the concepts of convolution, autocorrelation and power spectral density, for deterministic signals. It introduces the concepts of probability, random variables and stochastic processes, including autocorrelation, cross-correlation, power spectral and cross-spectral densities, for random signals, and their applications to the analysis of linear systems. This chapter also includes the response of specific non-linear systems, such as power amplifiers. The book presents amplitude modulation with random signals, including analog and digital signals, and discusses performance evaluation methods, presents quadrature amplitude modulation using random signals. Several modulation schemes are discussed, including SSB, QAM, ISB, C-QUAM, QPSK and MSK. Their autocorrelation and power spectrum densities are computed. A thorough discussion on angle modulation with random modulating signals, along with frequency and phase modulation, and orthogonal frequency division multiplexing is provided. Their power spectrum densities are computed using the Wiener-Khintchin theorem.
