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.

Explains the importance of Elastic Optical Networks (EONs) and how they can be implemented by the world’s carriers This book discusses Elastic Optical Networks (EONs) from an operational perspective. It presents algorithms that are suitable for real-time operation and includes experimental results to further demonstrate the feasibility of the approaches discussed. It covers practical issues such as provisioning, protection, and defragmentation. It also presents provisioning and recovery in single layer elastic optical networks (EON). The authors review algorithms for provisioning point-to-point, anycast, and multicast connections, as well as transfer-based connections for datacenter interconnection. They also include algorithms for recovery connections from failures in the optical layer and in-operation planning algorithms for EONs. Provisioning, Recovery and In-operation Planning in Elastic Optical Network also examines multi-layer scenarios. It covers virtual network topology reconfiguration and multi-layer recovery, and includes provisioning customer virtual networks and the use of data analytics in order to bring cognition to the network. In addition, the book: Presents managing connections dynamically—and the flexibility to adapt the connection bitrate to the traffic needs fit well for new types of services, such as datacenter interconnection and Network Function Virtualization (NFV) Examines the topic in a holistic and comprehensive way, addressing control and management plane issues for provisioning, recovery, and in-operation planning Covers provisioning, recovery, and in-operation planning for EONs at the proposed exhaustive level The rapid expanse of new services has made the use of EONs (a relatively new concept) a necessity. That’s why this book is perfect for students and researchers in the field of technologies for optical networks (specifically EONs), including network architectures and planning, dynamic connection provisioning, on-line network re-optimization, and control and management planes. It is also an important text for engineers and practitioners working for telecom network operators, service providers, and vendors that require knowledge on a rapidly evolving topic.

Elastic Optical Networks were proposed in response to the large capacity and diverse traffic granularity of the future Internet. Depending on the bandwidth requirements, EONs allocate an appropriate-sized spectrum to each connection. This new scheme breaks with the traditional WDM networks which uses static connections. Nevertheless, these networks resources are poorly used under dynamic traffic condition. This thesis proposes a hybrid scheme where resources are allocated both in a static and dynamic manner. It also pretends to give a solution to the principal drawback of the hybrid scheme, the inability to absorb random connection request peaks.

Elastic Optical Networks (EON) is widely accepted today as the next step in the evolution toward high capacity networking. The idea behind it is to optimize the use of resources by flexibly assigning spectrum, data rate and modulation format adapted to the needs of the end-to-end connection requests. This book is devoted to the study of three important issues in EONs, 1) dynamic source aggregation of sub-wavelength connections, 2) correlation between traffic granularity and defragmentation periodicity and 3) using spectrum fragmentation to better allocate time-varying connections.

This chapter introduces elastic optical networking, which is a new paradigm for the wavelength division multiplexing (WDM) layer, based on a much more flexible use of the spectrum without a rigid wavelength grid, transponders that can be programmed for different modulation formats, tightly packed channels in a so called “superchannel” and impairment-aware control planes that tie the client layer and the optical layer together. We start by reviewing the changes in network usage patterns that require an overhaul of the network architecture. We then survey the enabling technologies, including flexible spectrum reconfigurable add/drop multiplexers (FlexSpectrum ROADMs), bit rate variable transponders (also known as software defined), and control plane capabilities. We provide a vision of the resulting architecture, including how to decide on the connection bit rate and other properties and how to manage the spectrum, and compare it to today’s WDM systems. We finish by surveying progress in standards for this technology.

Flexgrid optical networks are emerging as an attractive solution for future high-speed optical transport, from the moment that the actual technology can offer high levels of flexibility and scalability to them, responding to the exponential growth of the Internet traffic. This thesis presents a simple strategy that helps to improve the spectrum usage in flexgrid optical networks which consists on limiting the bandwidth assigned to different connections. Adapting completely flexible optical networks to "multi-rate" optical networks shows that the performance of the links improve, only where connection bandwidth values are allowed if they are multiple of each other to avoid the maximum of spectrum voids that can't be used to reduce the network fragmentation. The results of the simulations confirm that by limiting the connection size at a given blocking probability, some gain is obtained at the cost of losing some flexibility in the network.
