Both authors have taught the course of "Distributed Systems" for many years in the respective schools. During the teaching, we feel strongly that "Distributed systems" have evolved from traditional "LAN" based distributed systems towards "Internet based" systems. Although there exist many excellent textbooks on this topic, because of the fast development of distributed systems and network programming/protocols, we have difficulty in finding an appropriate textbook for the course of "distributed systems" with orientation to the requirement of the undergraduate level study for today's distributed technology. Specifically, from - to-date concepts, algorithms, and models to implementations for both distributed system designs and application programming. Thus the philosophy behind this book is to integrate the concepts, algorithm designs and implementations of distributed systems based on network programming. After using several materials of other textbooks and research books, we found that many texts treat the distributed systems with separation of concepts, algorithm design and network programming and it is very difficult for students to map the concepts of distributed systems to the algorithm design, prototyping and implementations. This book intends to enable readers, especially postgraduates and senior undergraduate level, to study up-to-date concepts, algorithms and network programming skills for building modern distributed systems. It enables students not only to master the concepts of distributed network system but also to readily use the material introduced into implementation practices.

In Japan information technology has been a vital part of manufacturing for decades. A central factory computer provides a production plan and shop minicomputers and microcomputers in the factory run machines that manufacture products. It has become necessary to connect computers installed at different locations to enable information exchange between different sections. This requires an intracompany network with large memory capacity and high-speed communication capability to process documents, drawings, and image data, as well as conventional code data: a local area network (LAN). This volume discusses the ring-type LAN; the TOSLINE-8000 high-speed optical data highway for high-speed real-time control systems; the TOSLINE-2000E, a compact, low-cost independent local area network; the status of MAP, a communications protocol for manufacturing automation established by General Motors and MAP activities in Japan

The complexity of the UMTS system, new WCDMA technology, and new technical features set new requirements for the radio network planning area. The WCDMA-based UMTS networks need also more advanced and careful radio planning, optimization, and QOS management tasks in order to guarantee seamless mobility and connectivity for the end-user when various voice and data services are used. Hence, new detailed and practical radio planning, optimization, and QOS Management guidelines must be defined through the UMTS planning process. UMTS Radio Network Planning, Optimization and QOS Management describes practical planning process and gives solutions for detailed planning actions by following the planning process. The role of radio planning tool environment is emphasized by specifying the requirements of the digital map production, design tool, field measurement tool, and QOS measurement tool and by giving several examples of the results of these topics. efficient UMTS planning and optimization tool environment and to carry out a practical UMTS planning and optimization project from configuration planning to field and QOS measurements.

The breathtaking success of the WDM technology in backbone networks also pushes the development and implementation of optical packet-switched WDM local and metropolitan area networks. Local and metropolitan area optical WDM networks are emerging as viable and cost-effective solutions for many telecommunication operators and service providers who have to face an extremely growing bandwidth demand and expensive additional fiber installation costs. Thus, the strong need for the development of novel high-speed architectures and protocols for such networks arises. In Optical Packet Access Protocols for WDM Networks, different basic and novel medium access control (MAC) protocols for WDM-based LANs/MANs, typically belonging to the group of single-hop networks, are proposed and analyzed. Thereby, solutions for the direct and efficient support of distinct Quality-of-Service (QoS) classes over the WDM transmission layer are provided. Besides a comprehensive overview on the state-of-the-art photonic metro networks, highly dynamic reservation-based access protocols relying on the passive-star and the ring topology are presented while assuming the deployment of wavelength-tunable transceivers at the network nodes. Optical Packet Access Protocols for WDM Networks provides both a comprehensive survey on existing WDM local and metro lightwave systems and the design of novel highly efficient medium access control protocols with QoS support for such systems. Accordingly, this work is appropriate for communication and network engineers from both the academic and industrial world working in the field of optical communication networks, computer science, and communication engineering.

This book outlines the consequences of digitization for peer-reviewed research articles published in electronic journals. It has often been argued that digitization will revolutionize scientific communication. However, this study shows that this is not the case as far as scientific journals are concerned. Authors make little or no use of the possibilities offered by the digital medium, new procedures for electronic peer review have not replaced traditional peer review, and users do not seem to accept new forms of interaction offered by some electronic journals. The main innovations are to be found at the level of the infrastructures developed by publishers. Scientists themselves appear to be reluctant to change their established patterns of behaviour in formal scientific communication.

How do cables and data centers think? This book investigates how information infrastructures enact particular forms of knowledge. It juxtaposes the pervasive logics of speed, efficiency, and resilience with more communal and ecological ways of thinking and being, turning technical "solutions" back into open questions about what society wants and what infrastructures should do. Moving from data centers in Hong Kong to undersea cables in Singapore and server clusters in China, Munn combines rich empirical material with insights drawn from media and cultural studies, sociology, and philosophy. This critical analysis stresses that infrastructures are not just technical but deeply epistemological, privileging some actions and actors while sidelining others. This innovative exploration of the values and visions at the heart of our technologies will interest students, scholars, and researchers in the areas of communication studies, digital media, technology studies, sociology, philosophy of technology, information studies, and geography.

Position-based routing was originally developed for packet radio networks in the 1980s [6]. It received renewed interest during the last few years as a method for routing in mobile wireless ad hoc and sensor networks [1, 2, 4]. The general idea of is to select the next hop based on position information such that the packet is forwarded in the geographical direction of the destination. Position-based routing can be divided into two main components: the location service and position-based forwarding. The location service [5, 13] is used for mapping the unique identifier (for example an IP address) of a node to its geographical position. In mobile ad hoc networks, providing accurate location service for position based routing, with low communication overhead, appears to be more difficult task than routing itself [13]. In case of sensor networks, however, destination is a sink or base station whose position is made available to source sensors by flooding. Position-based forwarding is performed by a node to select one of its neighbors as the next hop the packet should be forwarded to. Usually, the following information is required for the forwarding decision: the node's own geographical position, the position of all neighbors within transmission range and the position of the destination. Based on this information, the forwarding node selects one of its neighbors as the next hop such that the packet makes progress toward the geographical position of the destination.

In these exciting times of quotidianly progressing developments in communication techniques, where more than ever in the history of a technological progress, society's reliance on communication networks for medicine, education, data transfer, commerce, and many other endeavours dominates the human's everyday life, the optical networks are certainly one of the most promising and challenging networking options. Since their commercial arrival in the nineties, they have fundamentally changed the way of dealing with traffic engineering by removing bandwidth bottlenecks and eliminating delays. Today, after the revolutionary bandwidth expansion, the networking functionality migrates more and more to the optical layer, and the need to establish fast wavelength circuits and capacity-on-demand for the higher-layer networks, in particular data networks based on Internet Protocol (IP), has become one of the central networking issues for the new century. The unifying trends toward configurable all-optical network infrastructure open up a wide range of new network engineering and design choices dealing with networks' interoperability and common platforms for control and management. The Fifth Working Conference on Optical Network Design and Modelling, held in the Austrian capital Vienna, February 5-7, 2001, aims at presenting the most recent progress in optical communication techniques, new technologies, standardisation process, emerging markets and carriers. A short look at the Table of Contents of this book tells us, in fact, that this year's conference program reflects the current state of the art precisely.
