This textbook was inspired by an undergraduate elective course given on virtual organizations and technology. The instructor could not find a suitable text that covered both the organizational and technological aspects including examples based on today's industry. Other books were either too strategic or too technical for an audience of undergraduate business and technology students who were to use the book. But why was that the case? For the same reason that business and IT people in industry tended not to speak the same "language": indeed, the integration of technology into business strategy has been a recent occurrence, and traditional strategy issues have been decided too high in the organizational structure while technology was too detailed in tactical implementation. With the Internet and the advent of e-commerce, m-commerce, and c-commerce (and the other letters of the alphabet soon to follow), business and technology finally started to become closer, and the interest in technology as an enabler for strategic business decision-making evolved into a mainstream concept. How are we defining a virtual organization? Most definitions of the concept of virtual organizations start with stating that it is "a network between organisations or individuals . . . ". The Oxford Concise Dictionary defines 'virtual' as: "that is such/or practical purposes, though not in name or according to a strict definition. " An organization may be thought of as a number of individuals systematically united for some end or work.

This book, written by leading experts from academia and industry, offers a condensed overview on hot topics among the Cognitive Radios and Networks scientific and industrial communities (including those considered within the framework of the European COST Action IC0902) and presents exciting visions for the future. Examples of the subjects considered include the design of new filter bank-based air interfaces for spectrum sharing, medium access control design protocols, the design of cloud-based radio access networks, an evolutionary vision for the development and deployment of cognitive TCP/IP, and regulations relevant to the development of a spectrum sharing market. The concluding chapter comprises a practical, hands-on tutorial for those interested in developing their own research test beds. By focusing on the most recent advances and future avenues, this book will assist researchers in understanding the current issues and solutions in Cognitive Radios and Networks designs.

Software Networks describe new concepts for the Internet s next generation. This architecture is based on virtual networking using Cloud and datacenter facilities. The main problems to be dealt with are the placement of virtual resources for opening a new network on the fly, and the urbanization of virtual resources implemented on physical network equipment. The digital architecture also deals with mechanisms capable of automatically controlling the placement of all virtual resources within the physical network. This book describes how to create and delete virtual networks on the fly. Indeed, the system is able to create any new network with any kind of virtual resource (e.g. switches, routers, LSRs, optical paths, firewalls, SIP-based servers, devices, servers, access points, etc.). Software Networks shows how this architecture is compatible with new advances in SDN (Software Defined Networking), new high-speed transport protocols such as TRILL (Transparent Interconnection of Lots of Links) and LISP (Locator/Identifier Separation Protocol), NGN, IMS, new generation Wi-Fi, and 4G/5G networks. Finally, the author introduces Clouds of security and the virtualization of secure elements (smartcards) that could certainly transform how to secure the Internet. For this second edition, the author addresses in five new chapters the importance of open source software for networks, mobile edge computing, fog networking, tactile internet - a network environment allowing remote access, and security - the use of Cloud of security, secure elements and the emergence of the blockchain.

Welcome to IWQOS'97 in New York City! Over the past several years, there has been a considerable amount of research within the field of Quality of Service (QOS). Much of that work has taken place within the context of QOS support for distributed multimedia systems, operating systems, transport subsystems, networks, devices and formal languages. The objective of the Fifth International Workshop on Quality of Service (IWQOS) is to bring together researchers, developers and practitioners working in all facets of QOS research. While many workshops and conferences offer technical sessions on the topic QOS, none other than IWQOS, provide a single-track workshop dedicated to QOS research. The theme of IWQOS'97 is building QOS into distributed systems. Implicit in that theme is the notion that the QOS community should now focus on discussing results from actual implementations of their work. As QOS research moves from theory to practice, we are interested in gauging the impact of ideas discussed at previous workshops on development of actual systems. While we are interested in experimental results, IWQOS remains a forum for fresh and innovative ideas emerging in the field. As a result of this, authors were solicited to provide experimental research (long) papers and more speculative position (short) statements for consideration. We think we have a great invited and technical program lined up for you this year. The program reflects the Program Committees desire to hear about experiment results, controversial QOS subjects and retrospectives on where we are and where we are going.

Queueing is an aspect of modern life that we encounter at every step in our daily activities. Whether it happens at the checkout counter in the supermarket or in accessing the Internet, the basic phenomenon of queueing arises whenever a shared facility needs to be accessed for service by a ]arge number of jobs or customers. The study of queueing is important as it gravides both a theoretical background to the kind of service that we may expect from such a facility and the way in which the facility itself may be designed to provide some specified grade of service to its customers. Our study of queueing was basically motivated by its use in the study of communication systems and computer networks. The various computers, routers and switches in such a network may be modelled as individual queues. The whole system may itself be modelled as a queueing network providing the required service to the messages, packets or cells that need to be carried. Application of queueing theory provides the theoretical framework for the design and study of such networks. The purpose of this book is to support a course on queueing systems at the senior undergraduate or graduate Ievels. Such a course would then provide the theoretical background on which a subsequent course on the performance modeHing and analysis of computer networks may be based.

It is important to understand what came before and how to meld new products with legacy systems. Network managers need to understand the context and origins of the systems they are using. Programmers need an understanding of the reasons behind the interfaces they must satisfy and the relationship of the software they build to the whole network. And finally, sales representatives need to see the context into which their products must fit.

Network calculus is a theory dealing with queuing systems found in computer networks. Its focus is on performance guarantees. Central to the theory is the use of alternate algebras such as the min-plus algebra to transform complex network systems into analytically tractable systems. To simplify the ana- sis, another idea is to characterize tra?c and service processes using various bounds. Since its introduction in the early 1990s, network calculus has dev- oped along two tracks-deterministic and stochastic. This book is devoted to summarizing results for stochastic network calculus that can be employed in the design of computer networks to provide stochastic service guarantees. Overview and Goal Like conventional queuing theory, stochastic network calculus is based on properly de?ned tra?c models and service models. However, while in c- ventional queuing theory an arrival process is typically characterized by the inter-arrival times of customers and a service process by the service times of customers, the arrival process and the service process are modeled in n- work calculus respectively by some arrival curve that (maybe probabilis- cally) upper-bounds the cumulative arrival and by some service curve that (maybe probabilistically) lower-bounds the cumulative service. The idea of usingboundstocharacterizetra?candservicewasinitiallyintroducedfor- terministic network calculus. It has also been extended to stochastic network calculus by exploiting the stochastic nature of arrival and service processes.

This text, intended for a first course in performance evaluation, provides a self-contained treatment of all aspects of queueing theory. It starts by introducing readers to the terminology and usefulness of queueing theory and continues by considering Markovian queues in equilibrium, Little's law, reversibility, transient analysis and computation, and the M/G/1 queueing system. Subsequent chapters treat the theory of networks of queues and computational algorithms for networks of queues. Stochastic Petri networks, including those whose solutions can be given in product form, are covered in detail. A chapter on discrete-time queueing systems, which are of recent interest, discusses arrival processes, Geom/Geom/m queueing models, and case studies of discrete-time queueing networks arising in industrial applications. This third edition includes a new chapter on current models of network traffic as well as sixteen new homework problems on discrete-time models and a revised and updated set of references. The discussion of network traffic models includes a survey of continuous and discrete time models, a detailed discussion of burstiness, a complete introduction to self-similar traffic and a presentation of solution techniques. Solutions for all of the homework problems in this text are available in a separate volume.

The book presents theory and algorithms for secure networked inference in the presence of Byzantines. It derives fundamental limits of networked inference in the presence of Byzantine data and designs robust strategies to ensure reliable performance for several practical network architectures. In particular, it addresses inference (or learning) processes such as detection, estimation or classification, and parallel, hierarchical, and fully decentralized (peer-to-peer) system architectures. Furthermore, it discusses a number of new directions and heuristics to tackle the problem of design complexity in these practical network architectures for inference.

The present textbook contains the recordsof a two-semester course on que- ing theory, including an introduction to matrix-analytic methods. This course comprises four hours oflectures and two hours of exercises per week andhas been taughtattheUniversity of Trier, Germany, for about ten years in - quence. The course is directed to last year undergraduate and?rst year gr- uate students of applied probability and computer science, who have already completed an introduction to probability theory. Its purpose is to present - terial that is close enough to concrete queueing models and their applications, while providing a sound mathematical foundation for the analysis of these. Thus the goal of the present book is two-fold. On the one hand, students who are mainly interested in applications easily feel bored by elaborate mathematical questions in the theory of stochastic processes. The presentation of the mathematical foundations in our courses is chosen to cover only the necessary results, which are needed for a solid foundation of the methods of queueing analysis. Further, students oriented - wards applications expect to have a justi?cation for their mathematical efforts in terms of immediate use in queueing analysis. This is the main reason why we have decided to introduce new mathematical concepts only when they will be used in the immediate sequel. On the other hand, students of applied probability do not want any heur- tic derivations just for the sake of yielding fast results for the model at hand.

Current middleware solutions, e.g., application servers and Web services, are very complex software products that are hard to tame because of intricacies of distributed systems. Their functionalities have mostly been developed and managed with the help of administration tools and corresponding configuration files, recently in XML. Though this constitutes flexibility for developing and administrating a distributed application, the conceptual model underlying the different configurations is only implicit.

To remedy such problems, Semantic Management of Middleware contributes an ontology-based approach to support the development and administration of middleware-based applications. The ontology is an explicit conceptual model with formal logic-based semantics. Its descriptions may therefore be queried, may foresight required actions, or may be checked to avoid inconsistent system configurations.

This book builds a rigorous approach towards giving the declarative descriptions of components and services a well-defined meaning by specifying ontological foundations and by showing how such foundations may be realized in practical, up-and-running systems.
