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.

Effective knowledge work depends on bringing people together to form a team with the right mix of expertise for the project or problem on hand. Increasingly, that mix can only be created by finding people who are geographically dispersed across sites of the company or across several companies. These virtual teams typically work by linking through electronic tools, such as the telephone, fax, email, NetMeeting, Lotus Notes, and other web-based communication systems. Recent research suggests that these teams have all of the challenges of face-to-face teams in addition to others, such as the limitations of technology, cultural differences, and multiple supervisors. The papers included in this volume identify some of the problems and some of the solutions to these kinds of problems, but most importantly, in a dynamic field such as virtual teams, the papers provide a framework for thinking about such problems and a collection of ideas that can form a foundation for advancing both research and practice in the field. Much of the literature on virtual teams focuses on the technology. The technology is an enabler, but it does not seem to have advanced far enough to make electronic communications as effective as face-to-face meetings. Like other teams, virtual teams consist of human beings and they have interpersonal and identity needs that must be met to optimize their ability to work and to collaborate. So, issues such as member solidarity, cooperation and unity of actions and values become special concerns. Such issues are addressed in this volume with the hope that this work will provide a foundation for moving ahead in this field toward more effective virtual teams.

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

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.

Rails 7 completely redefines what it means to produce fantastic user experiences and provides a way to achieve all the benefits of single-page applications - at a fraction of the complexity. Rails 7 integrates the Hotwire frameworks of Stimulus and Turbo directly as the new defaults, together with that hot newness of import maps. The result is a toolkit so powerful that it allows a single individual to create modern applications upon which they can build a competitive business. The way it used to be. Ruby on Rails helps you produce high-quality, beautiful-looking web applications quickly - you concentrate on creating the application, and Rails takes care of the details. Rails 7 brings many improvements, and this edition is updated to cover the new features and changes in best practices. We start with a step-by-step walkthrough of building a real application, and in-depth chapters look at the built-in Rails features. Follow along with an extended tutorial as you write a web-based store application. Eliminate tedious configuration and housekeeping, seamlessly incorporate JavaScript, send and receive emails, manage background jobs with ActiveJob, and build real-time features using WebSockets and ActionCable. Test your applications as you write them using the built-in unit, integration, and system testing frameworks, internationalize your applications, and deploy your applications easily and securely. Rails 1.0 was released in December 2005. This book was there from the start, and didn't just evolve alongside Rails, it evolved with Rails. It has been developed in consultation with the Rails core team. In fact, Rails itself is tested against the code in this book. What You Need: All you need is a Windows, Mac OS X, or Linux machine to do development on. This book will take you through the steps to install Rails and its dependencies. If you aren't familiar with the Ruby programming language, this book contains a chapter that covers the basics necessary to understand the material in the book.

There are numerous factors contributing to the dynamic growth of wireless communication systems we've been observing in the past 10 years, the most important being the increasing network user mobility and the technological advances in high-speed data transmission over radio channels. Research centres and standards-making institutions the world over conduct works on 3G integrated systems of person-to-person and person-to-computer communications, wireless counterparts of classical LAN, ATM and IP architectures, satellite and access networks as well as advanced service platforms like W AP and other concepts. Among the many commercial and non-profit organisations professionally involved in the development of the new information infrastructure, of particular influence is the International Federation for Information Processing. Within its Technical Committee TC-6, a working group WG 6.8 has been set up to co-ordinate IFIP activities in the area of wireless communications. It has done so, among others, by arranging regular meetings of academic and industrial researchers, known as IFIP TC-6 WG 6.8 Workshops on Personal Wireless Communications (pWC). Such workshops were held in recent years in Prague, Frankfurt/M, Tokyo and Copenhagen, and their success has resulted in the promotion of PWC to the status of IFIP Working Conference.
