This book provides a thorough development of the powerful methods of heavy traffic analysis and approximations with applications to a wide variety of stochastic (e.g. queueing and communication) networks, for both controlled and uncontrolled systems. The approximating models are reflected stochastic differential equations. The analytical and numerical methods yield considerable simplifications and insights and good approximations to both path properties and optimal controls under broad conditions on the data and structure. The general theory is developed, with possibly state dependent parameters, and specialized to many different cases of practical interest. Control problems in telecommunications and applications to scheduling, admissions control, polling, and elsewhere are treated. The necessary probability background is reviewed, including a detailed survey of reflected stochastic differential equations, weak convergence theory, methods for characterizing limit processes, and ergodic problems.

It is always confusing, and perhaps inconvenient at times, using generic terms that will mean something to everyone but different things to different people. "High Performance" is one of those terms. High Performance can be viewed as synonymous to High Speed or Low Latency or a number of other characteristics. The interesting thing is that such ambiguity can sometimes be useful in a world where focus shifts quite easily from one issue to another as times and needs evolve. Many things have changed since the first HPN conference held in Aachen, Germany in 1987. The focus then was mainly on Media Access Control (MAC) protocols that allow users to share the high bandwidth of optical fiber. FDDI (Fiber Distributed Data Interface) was making its debut with its amazing 100 Mbps speed. ATM (Asynchronous Transfer Mode) and SONET (the Synchronous Optical Network) were beginning to capture our imagination. What could users possibly do with such "high performance"? Share it! After realizing that the real problems had gradually shifted away from the network media to the periphery of the network, focus also began to shift. Adapter design, protocol implementation, and communication systems architecture began to attract our interest. Networking -not Networks-became the hot issue.

Channel 2 System Output at Detector ................................. 621 PREFACE The emerging networks in our society will touch upon the life of everyone. These networks have started to bring about an immense information revolution. The revolution within our intellectual life will be similar to the materialistic revolution that followed the invention of the steam and the internal combustion engines. From the perspective of the 1980s, the information networks are indeed evolving and their influence can only be gradual. However, the strides of progress are accelerating in the 1990s. Networks in our society offer the most candid area of convergence for the computer and the communication technologies. The two technologies are mature in their own right. However, there are a few major factors that prevent network engineers from constructing modern communication systems from components borrowed from each of these two technologies: * Major innovations are happening. * Specialized components evolve in synergistic patterns. * New technologies emerge. * Inquisitive minds cross disciplinary barriers.

Welcome to the third International Conference on Management of Multimedia Networks and Services (MMNS'2000) in Fortaleza (Brazil) The first MMNS was held in Montreal ( Canada) in july 1997 and the second MMNS was held in Versailles (France) in November 1998. The MMNS conference takes place every year and a half and is aimed to be a truly international event by bringing together researchers and practitioners from all around the world and by organising the conference each time in a different continent/country. Over the past several years, there has been a considerable amount of research within the fields of multimedia networking and network management. Much of that work has taken place within the context of managing Quality-of Service in broadband integrated services digital networks such as the A TM, and more recently in IP-based networks, to respond to the requirements of emerging multimedia applications. A TM networks were designed to support multimedia traffic with diverse characteristics and can be used as the transfer mode for both wired and wireless networks. A new set of Internet protocols is being developed to provide better quality of service, which is a prerequisite for supporting multimedia applications. Multimedia applications have a different set of requirements, which impacts the design of the underlying communication network as well as its management. Several QoS management mechanisms intervening at different layers of the communication network are required including QoS-routing, QoS-based transport, QoS negotiation, QoS adaptation, FCAPS management, and mobility management."

In today s world, services and data are integrated in ever new constellations, requiring the easy, flexible and scalable integration of autonomous, heterogeneous components into complex systems at any time.

Event-based architectures inherently decouple system components. Event-based components are not designed to work with specific other components in a traditional request/reply mode, but separate communication from computation through asynchronous communication mechanisms via a dedicated notification service.

Muhl, Fiege, and Pietzuch provide the reader with an in-depth description of event-based systems. They cover the complete spectrum of topics, ranging from a treatment of local event matching and distributed event forwarding algorithms, through a more practical discussion of software engineering issues raised by the event-based style, to a presentation of state-of-the-art research topics in event-based systems, such as composite event detection and security. Their presentation gives researchers a comprehensive overview of the area and lots of hints for future research. In addition, they show the power of event-based architectures in modern system design, thus encouraging professionals to exploit this technique in next generation large-scale distributed applications like information dissemination, network monitoring, enterprise application integration, or mobile systems.

The consecutive-k system was first studied around 1980, and it soon became a very popular subject. The reasons were many-folded, includ ing: 1. The system is simple and natural. So most people can understand it and many can do some analysis. Yet it can grow in many directions and there is no lack of new topics. 2. The system is simple enough to become a prototype for demonstrat ing various ideas related to reliability. For example, the interesting concept of component importance works best with the consecutive-k system. 3. The system is supported by many applications. Twenty years have gone and hundreds of papers have been published on the subject. This seems to be a good time for retrospect and to sort the scattered material into a book. Besides providing our own per spective, the book will also serve as an easy reference to the numerous ramifications of the subject. It is hoped that a summary of work in the current period will become the seed of future break-through."

In today's market, emerging technologies are continually assisting in common workplace practices as companies and organizations search for innovative ways to solve modern issues that arise. Prevalent applications including internet of things, big data, and cloud computing all have noteworthy benefits, but issues remain when separately integrating them into the professional practices.

Active networking is an exciting new paradigm in digital networking that has the potential to revolutionize the manner in which communication takes place. It is an emerging technology, one in which new ideas are constantly being formulated and new topics of research are springing up even as this book is being written. This technology is very likely to appeal to a broad spectrum of users from academia and industry. Therefore, this book was written in a way that enables all these groups to understand the impact of active networking in their sphere of interest. Information services managers, network administrators, and e-commerce developers would like to know the potential benefits of the new technology to their businesses, networks, and applications. The book introduces the basic active networking paradigm and its potential impacts on the future of information handling in general and on communications in particular. This is useful for forward-looking businesses that wish to actively participate in the development of active networks and ensure a head start in the integration of the technology in their future products, be they applications or networks. Areas in which active networking is likely to make significant impact are identified, and the reader is pointed to any related ongoing research efforts in the area. The book also provides a deeper insight into the active networking model for students and researchers, who seek challenging topics that define or extend frontiers of the technology. It describes basic components of the model, explains some of the terms used by the active networking community, and provides the reader with taxonomy of the research being conducted at the time this book was written. Current efforts are classified based on typical research areas such as mobility, security, and management. The intent is to introduce the serious reader to the background regarding some of the models adopted by the community, to outline outstanding issues concerning active networking, and to provide a snapshot of the fast-changing landscape in active networking research. Management is a very important issue in active networks because of its open nature. The latter half of the book explains the architectural concepts of a model for managing active networks and the motivation for a reference model that addresses limitations of the current network management framework by leveraging the powerful features of active networking to develop an integrated framework. It also describes a novel application enabled by active network technology called the Active Virtual Network Management Prediction (AVNMP) algorithm. AVNMP is a pro-active management system; in other words, it provides the ability to solve a potential problem before it impacts the system by modeling network devices within the network itself and running that model ahead of real time.

In the same way that infrastructures such as transportation, electricity, sewage, and water supply are widely assumed to be integrators of urban spaces, information infrastructures are assumed to be integrators of information spaces. With the advent of Web 2.0 and new types of information infrastructures such as online social networks and smart mobile platforms, a more in-depth understanding of the various rights to access, use, develop, and modify information infrastructure resources is necessary. Perspectives and Implications for the Development of Information Infrastructures aims at addressing this need by offering a fresh new perspective on information infrastructure development. It achieves this by drawing on and adapting theory that was initially developed to study natural resource commons arrangements such as inshore fisheries, forests, irrigation systems, and pastures, while placing great emphasis on the complex problems and social dilemmas that often arise in the negotiations.

This book addresses the changing role of networks and the evolving structure of an Infrastructure Superhighway. The requirements for leadership in telecommunications are reviewed from different viewpoints: Network operators, equipment manufacturers, software developers and user organizations. Emphasis is placed on multimedia and what multimedia solutions would mean to telephone utilities and endusers. Based on extensive research undertaken in Europe, US and Japan, Dimitris Chorafas identifies new domains of applications, presents the breakthroughs which have currently been achieved and outlines the systems solutions necessary to fruitfully exploit new technology.

Multi-Threaded Object-Oriented MPI-Based Message Passing Interface: The ARCH Library presents ARCH, a library built as an extension to MPI. ARCH relies on a small set of programming abstractions that allow the writing of well-structured multi-threaded parallel codes according to the object-oriented programming style. ARCH has been written with C++. The book describes the built-in classes, and illustrates their use through several template application cases in several fields of interest: Distributed Algorithms (global completion detection, distributed process serialization), Parallel Combinatorial Optimization (A* procedure), Parallel Image-Processing (segmentation by region growing). It shows how new application-level distributed data types - such as a distributed tree and a distributed graph - can be derived from the built-in classes. A feature of interest to readers is that both the library and the application codes used for illustration purposes are available via the Internet. The material can be downloaded for installation and personal parallel code development on the reader's computer system. ARCH can be run on Unix/Linux as well as Windows NT-based platforms. Current installations include the IBM-SP2, the CRAY-T3E, the Intel Paragon, PC-networks under Linux or Windows NT. Multi-Threaded Object-Oriented MPI-Based Message Passing Interface: The ARCH Library is aimed at scientists who need to implement parallel/distributed algorithms requiring complicated local and/or distributed control structures. It can also benefit parallel/distributed program developers who wish to write codes in the object-oriented style. The author has been using ARCH for several years as a medium to teach parallel and network programming. Teachers can employ the library for the same purpose while students can use it for training. Although ARCH has been used so far in an academic environment, it will be an effective tool for professionals as well. Multi-Threaded Object-Oriented MPI-Based Message Passing Interface: The ARCH Library is suitable as a secondary text for a graduate level course on Data Communications and Networks, Programming Languages, Algorithms and Computational Theory and Distributed Computing and as a reference for researchers and practitioners in industry.

'The world of information processing is going through a major phase of its evolution. Networking has been associated with computers since the 1960's. Communicating machines, exchanging information or cooperating to solve complex problems, were the dream of many scientists and engineers. Rudi mentary networks and protocols were invented. Local area networks capable of carrying a few megabits per second became basic components of corporate computing installations in the 1980's. At the same time, advances in optical transmission and switching technologies made it possible to transfer billions of bits per second. 'The availability of this huge bandwidth is making people wonder about the seemingly unlimited possibilities of these "fat information pipes" A new world where all interesting up-to-date information becomes instantaneously available to everyone everywhere is often portrayed to be around the comer. New applications are envisioned and their requirements are defined. 'The new field of High Performance Networking is burgeoning with activities at various levels. Several frontiers are being explored simultaneously. In order to achieve more bandwidth and better performance, work is progressing in optical transmission, high speed switching and network resource manage ment. Some researchers have started to investigate all-optical networking as a promising approach to remove the relatively slow electronics from the network infrastructure. This will also introduce a new environment with unique characteristics that will have a definite impact on network architec tures, topologies, addressing schemes, and protocols."
