Описание: Wavelength filters constitute an essential element of fibre-optic networks. This book gives a comprehensive account of the principles and applications of such filters, including their technological realisation. After an introductory chapter on wavelength division multiplexing in current and future fibre optic networks follows a detailed treatment of the phase characteristics of wavelength filters, a factor frequently neglected but of significant importance at high bit rates. Subsequent chapters cover three-dimensional reflection of gratings, arrayed waveguide gratings, fibre Bragg gratings, Fabry-Perot filters, dielectric multilayer filters, ring filters, and interleavers. The book explains the relevant performance parameters, the particular advantages and shortcomings of the various concepts and components, and the preferred applications. It also includes in-depth information on the characteristics of both commercially available devices and those still at the R&D stage. All chapters are authored by internationally recognized experts.

Описание: Most of the core backbone networks evolve to mesh topologies utilizing intelligent network elements for provisioning and restoration of services. Most, if not all, transport networks might move away from ring architectures to mesh architectures over the next 5 years. This book combines both theoretical aspects as well as practical aspects of routing and dimensioning for mesh optical networks. All authors were or are working as technical leaders for equipment vendors who have implemented such capabilities in their products, and whose products have been deployed in service provider networks.The book will cover most aspects of routing path-protected connections in restorable mesh optical networks. While the technology the book describes is that of optical networks, most of the concepts and algorithms apply to ATM (Asynchronous Transfer Mode) and IP/MPLS (Internet Protocol/Multi Protocol Label Switching) networks as well.
Описание: Wireless Sensor Networks have a wide range of applications in different areas. Their main constraint is the limited and irreplaceable power source of the sensor nodes. In many applications, energy conservation of the sensor nodes and their replacement or replenishment due to the hostile nature of the environment is the most challenging issue. Energy efficient clustering and routing are the two main important topics studied extensively for this purpose. This book focuses on the energy efficient clustering and routing with a great emphasis on the evolutionary approaches. It provides a comprehensive and systematic introduction of the fundamentals of WSNs, major issues and effective solutions.
Описание: This book focuses on methods for service-differentiated and constraint-based wavelength routing and resource allocation for multi-service WDM networks, tailored at needs of specific network users and adaptable to services yet to emerge. A number of unique routing solutions are proposed, and an extensive analysis of dynamically re-configurable multi-service WDM networks impart the major contribution to the current efforts in standardisation and network operation, and give an inimitable motivation for further study and research.
Описание: Transmission-Efficient Design and Management of Wavelength-Routed Optical Networks is a comprehensive treatment of the impact of transmission impairments on the design and management of wavelength-routed optical networks. It considers mesh-type network topologies and presents efficient algorithms and protocols for cost-effective deployment. Starting with transparent networks, this work focuses on power implications such as cross-connect design, device allocation problems, and management issues. In this all-optical model, a power-efficient design space, based on reduction in overall cost and ease of network management, is presented. This design concept, motivates various switch architectures and different optimization problems. Problems motivated by this design concept are addressed from both their theoretical and experimental aspects. After that, the book departs from pure transparent networks and allows for signal regeneration at some strategic locations in the network. Efficient design algorithms and signaling protocols are proposed which take advantage of the non-homogeneous nature of optical resources. Transmission-Efficient Design and Management of Wavelength-Routed Optical Networks is an invaluable resource targeted towards practitioners, researchers, and students from telecommunications, computer science, engineering, and networking with interest in the realistic deployment of optical networks in the metro and the backbone.
Описание: Explaining what CWDM is, how it is achieved, and why it should be deployed, "Coarse Wavelength Division Multiplexing: Technologies and Applications"
merges coverage of isolated aspects of Coarse Wavelength Division Multiplexing (CWDM) traditionally found as device-related or specific system topics. Emphasizing cost savings and
performance enhancement, the book integrates information on component issues, system architectures, concepts for extensions and upgrades, as well as practical applications into a
comprehensive, single-volume resource. Beginning with a summary of the ITU-T standards defining CWDM, the book addresses the three essential component classes, optical fibers,
transceivers, and WDM filters, which combine to form the basis for the CWDM transmission link.
The following chapters include coverage of different architectures such as
hubbed rings and meshed networks, and upgrade paths to overcome limitations of current CWDM systems. The book outlines the feasibility of optically amplified CW
M systems, investigates the challenges present with high-speed CWDM and bidirectional transmission, and finally elucidates the importance of CWDM for a wide range of applications.
Each chapter provides sufficient information to be used independently and contains references to relevant papers and articles for further study.
The last sections of the book
focus on applications and case studies where CWDM plays an ever-increasing role. They include extensive studies on networking, reach extension by amplification, and the latest
concepts of transmission capacity upgrades using increased bit-rates or new channel plans. Filled with practical information, the book provides a clear understanding of recent
developments in the dynamic field of CWDM.

Описание: All-optical networking is generally believed to be the only solution for coping with the ever-increasing demands in bandwidth, such as the World Wide Web application. Optical backbone networks efficiently achieve a high level of traffic aggregation by multiplexing numerous users on circuit-switched wavelength paths - the so-called wavelength routing approach. In contrast, the reduced level of traffic aggregation in access and metro networks makes wavelength routing solutions not adequate. In these network areas, packet-interleaved optical time-division multiplexing with its finer and more dynamic bandwidth allocation is advocated. The book presents such an approach, known as photonic slot routing. It illustrates how this approach may provide a cost-effective solution to deploying all-optical transport networks, using today's optical device technology. To that end, the author combines DWDM-technology with fixed slot optical switching, and gives a comprehensive description of this approach in which slots are aligned across the wavelengths to form groups of data-flows that propagate as a whole inside the network. Operating algorithms are developed, and network performance is analyzed, both by means of theoretical analysis and many simulations of sample networks. This work will be of particular interest to researchers and professionals who are active in photonic networking.
Описание: Routing and Quality-of-Service in Broadband LEO Satellite Networks describes mechanisms for supporting Quality-of-Service (QoS) strategies that consider properties of low earth orbit satellite networks and their effects on link handover. A graph model representing the dynamic topology of a satellite constellation is introduced based on a new parameter, lifetime. Novel routing and resource reservation algorithms as well as connection admission control strategies are proposed to minimize the handover blocking probability while maintaining QoS requirements. The author also discusses the roles of satellites in an all-IP mobile network architecture and the problems of mobility, QoS provisioning, and routing. This work will be of particular interest to researchers and professionals working on mobility networking in next generation networks.
