Available in PDF, EPUB and Kindle. Book excerpt: Transport networks evolved from DCS (Digital Cross-connect Systems)-based mesh architectures, to SONET/SDH (Synchronous Optical Networking/Synchronous Digital Hierarchy) ring architectures in the 1990’s. In the past few years, technological advancements in optical transport switches have allowed service providers to support the same fast recovery in mesh networks previously available in ring networks while achieving better capacity efficiency and resulting in lower capital cost. Optical transport networks today not only provide trunking capacity to higher-layer networks, such as inter-router connectivity in an IP-centric infrastructure, but also support efficient routing and fast failure recovery of high-bandwidth services. This is possible due to the emergence of optical network elements that have the intelligence required to efficiently control the network. Optical mesh networks will enable a variety of dynamic services such as bandwidth-on-demand, Just-In-Time bandwidth, bandwidth scheduling, bandwidth brokering, and optical virtual private networks that open up new opportunities for service providers and their customers alike. Path Routing in Mesh Optical Networks combines both theoretical as well as practical aspects of routing and dimensioning for mesh optical networks. All authors have worked as technical leaders for the equipment vendor Tellium who implemented such capabilities in its product, and whose product was deployed in service provider networks. Path Routing in Mesh Optical Networks Presents an in-depth treatment of a specific class of optical networks, i.e. path-oriented mesh optical networks. Focuses on routing and recovery, dimensioning, performance analysis and availability in mesh optical networks. Explains and analyses routing specifically associated with Dedicated Backup Path Protection (DBPP) and Shared Backup Path Protection (SBPP) recovery architectures. As most of the core backbone networks evolve to mesh topologies utilizing intelligent network elements for provisioning and recovery of services, Path Routing in Mesh Optical Networks will be an invaluable tool for both researchers and engineers in the industry who are responsible for designing, developing, deploying and maintaining mesh optical networks. It will also be a useful reference book for graduate students and university professors who are interested in optical networks or telecommunications networking. With a foreword by Professor Wayne D. Grover, author of the book Mesh-Based Survivable Networks.

Book excerpt: This book presents an in-depth treatment of routing and wavelength assignment for optical networks, and focuses specifically on quality-of-service and fault resiliency issues. It reports on novel approaches for the development of routing and wavelength assignment schemes for fault-resilient optical networks, which improve their performance in terms of signal quality, call blocking, congestion level and reliability, without a substantial increase in network setup cost. The book first presents a solution for reducing the effect of the wavelength continuity constraint during the routing and wavelength assignment phase. Further, it reports on an approach allowing the incorporation of a traffic grooming mechanism with routing and wavelength assignment to enhance the effective channel utilization of a given capacity optical network using fewer electrical-optical-electrical conversions. As a third step, it addresses a quality of service provision scheme for wavelength-division multiplexing (WDM)-based optical networks. Lastly, the book describes the inclusion of a tree-based fault resilience scheme in priority-based dispersion-reduced wavelength assignment schemes for the purpose of improving network reliability, while maintaining a better utilization of network resources. Mainly intended for graduate students and researchers, the book provides them with extensive information on both fundamental and advanced technologies for routing and wavelength assignment in optical networks. The topics covered will also be of interest to network planners and designers.

Available in PDF, EPUB and Kindle. Book excerpt: The rapid growth in communications and internet has changed our way of life, and our requirement for communication bandwidth. Optical networks can enable us to meet the continued demands for this bandwidth, although conventional optical networks struggle in achieving this, due to the limitation of the electrical bandwidth barrier. Flexgrid technology is a promising solution for future high-speed network design. To promote an efficient and scalable implementation of elastic optical technology in the telecommunications infrastructure, many challenging issues related to routing and spectrum allocation (RSA), resource utilization, fault management and quality of service provisioning must be addressed. This book reviews the development of elastic optical networks (EONs), and addresses RSA problems with spectrum fragment issues, which degrade the quality of service provisioning. The book starts with a brief introduction to optical fiber transmission system, and then provides an overview of the wavelength division multiplexing (WDM), and WDM optical networks. It discusses the limitations of conventional WDM optical networks, and discusses how EONs overcome these limitations. It presents the architecture of the EONs and its operation principle. To complete the discussion of network architecture, this book focuses on the different node architectures, and compares their performance in terms of scalability and flexibility. It reviews and classifies different RSA approaches, including their pros and cons. It focuses on different aspects related to RSA. The spectrum fragmentation is a serious issue in EONs, which needs to be managed. The book explains the fragmentation problem in EONs, discusses, and analyzes the major conventional spectrum allocation policies in terms of the fragmentation effect in a network. The taxonomies of the fragmentation management approaches are presented along with different node architectures. State-of-the-art fragmentation management approaches are looked at. A useful feature of this book is that it provides mathematical modeling and analyzes theoretical computational complexity for different problems in elastic optical networks. Finally, this book addresses the research challenges and open issues in EONs and provides future directions for future research.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, with the rapid growth of the Internet, the bandwidth demand for data traffic is exploding. Optical networks based on wavelength-division multiplexing (WDM) technology offer the promise to satisfy the bandwidth requirements of the Internet infrastructure. With WDM technology, signals are carried simultaneously on mUltiple wavelengths on a single fiber. WDM provides a practical approach of resolving the mismatch between the fiber ca pacity and the peak electronic processing speed. Mesh-based WDM networks have recently attracted much research and development interest since the In ternet topology is meshed in nature, and more importantly, mesh-based WDM networks are flexible with respect to routing and survivability. This book exam ines the management and survivability issues of mesh-based WDM networks and proposes new WDM network protocols and algorithms that could make telecommunication networks more efficient. Wavelength-routing has been one of the most important technologies to em ploy WDM in backbone networks. In wavelength-routed WDM networks, optical channels, which are referred to as lightpaths, are set up between WDM terminals. Most chapters of this bock are focused on various issues related to wavelength-routed networks, namely, routing and wavelength-assignment, con trol and management, fault management, and wavelength-converter placement. This book also presents an all-optical packet-switched network architecture based on the concept of photonic slot routing. The audience for this book are network designers and planners, research and development engineers active in the field of telecommunications, and students of optical networking at the graduate or senior undergraduate levels.

Integrating the service-oriented IP layer together with the efficient transport capabilities of the optical layer is a cornerstone of this research. Converged IP-optical networks are being demonstrated in large multi-carrier and multi-vendor venues. Research is continuing on making this convergence more efficient, flexible, and scalable. In this chapter, we review the current key technologies that contribute to the convergence of IP and optical networks, describing control and management plane technologies, techniques and standards in some detail. We also illustrate current research challenges, and discuss future directions for research.

This book was released on 2012-12-06 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
