New components and subsystems for very high speed optical networks offer new design opportunities to network operators and designers. The trends towards dynamically configurable all-optical network infrastructures open up a wide range of new network engineering and design choices, which must face issues such as interoperability and unified control and management.
Optical network design and modelling is an essential issue for planning and operating networks for the next century. The main issues in optical networking are being widely investigated not only for WDM networks but also for optical TDM and optical packet switching. This book aims to contribute to further progress in optical network architectures, design, operation and management and covers the following topics in detail: OAM functions and layered design of photonic networks; network planning and design; network modelling; analysis and protocols of optical LANs; network availability and performance modelling.
Within the past few decades, information technologies have been evolving at a tremendous rate, causing profound changes to our world and our ways of life. In particular, fiber optics has been playing an increasingly crucial role within the telecommunication revolution. Not only most long-distance links are fiber based, but optical fibers are increasingly approaching the individual end users, providing wide bandwidth links to support all kinds of data-intensive applications such as video, voice, and data services.
As an engineering discipline, fiber optics is both fascinating and challenging. Fiber optics is an area that incorporates elements from a wide range of techno- gies including optics, microelectronics, quantum electronics, semiconductors, and networking.
As a result of rapid changes in almost all of these areas, fiber optics is a fast evolving field. Therefore, the need for up-to-date texts that address this growing field from an interdisciplinary perspective persists. This book presents an overview of fiber optics from a practical, engineering perspective.
Therefore, in addition to topics such as lasers, detectors, and optical fibers, several topics related to electronic circuits that generate, detect, and process the optical signals are covered. Optical network design and modeling is an essential issue for planning and operating networks for the next century.
The main issues in optical networking are being widely investigated, not only for WDM networks but also for optical TDM and optical packet switching. This valuable new book will be essential reading for academic researchers and practitioners working in computer science, electrical engineering, and communications. The 39 revised full papers were carefully reviewed and selected from 87 submissions.
Vivek Alwayn is the author of this book. Optical Network Design and Implementation provides a complete reference of technology solutions for next-generation optical networks. The book explains the differences among various LAN technologies, getting you up to speed on the solutions you need to use.
Optical Network Design and Implementation contains a broad range of technical details on multiservice optical networking and covers optical networking theory, design, and configuration by providing informative text, illustrations, and examples.
It can be used as a reference for anyone designing, implementing, or supporting an optical network. Even if you are not using Cisco ONS equipment, this book can increase your awareness and understanding of optical technologies and provide you with detailed design concepts and rules for building highly scalable multiservice optical networks. This book covers the entire spectrum of optical networking technologies from the physical layer to the network layer. Optical Network Design and Planning takes a pragmatic approach to deploying state-of-the-art optical networking equipment in metro-core and backbone networks.
The ramifications of this technology are manifold, affecting the architecture, operation, and economics of the network, all of which are covered in the book. Algorithms and methodologies related to routing, regeneration, wavelength assignment, subrate-traffic grooming, and protection are presented, with an emphasis on optical-bypass-enabled or all-optical networks.
The focus is on techniques that have been proven to produce efficient results in realistic carrier networks. All of the algorithms presented scale well with network size so that they are suitable for real-time design. While the algorithms and architecture are the core of the content, the various optical network elements are covered as well, including a historical perspective and the implications of equipment evolution. The book has a large emphasis on the economics of optical networking, with a full chapter of economic studies that offer guidelines as to when and how optical-bypass technology should be deployed.

The Cisco Transport Planner is a fully comprehensive DWDM network design and design management tool for example, delta planning, rack layout definition, and cabling procedure that allows Cisco ONS MSTP customers to concentrate on service definition and availability while radically simplifying the process of comparing alternative service-delivery and investment scenarios.
The output from Cisco Transport Planner provides content beneficial to both the design and deployment phases, including system performance reporting, bill-of-materials BoM generation, graphical layouts of racks and shelf configurations, optical connections between nodes, and downloadable provisioning and configuration settings for each optical node.
Designing DWDM networks has always been a complex task because of the intrinsic nature of optical transmission, which is based on analog technology despite the transport of digital signals. Many different parameters must be accounted for because of linear and nonlinear effects. Linear effects include noise accumulation, optical power budget, and chromatic dispersion effects; nonlinear effects include cross-phase modulation, self-phase modulation, and four-wave mixing. The design and optimization of a DWDM network is an interactive process that requires consideration of all the constraints of the system:.
Based on these constraints, a DWDM network design should optimize the hardware placement in the different network nodes to minimize the cost of the design. The network design tool needs to account for and support this flexibility to verify and support the different optical paths existing in the network. These benefits surpass those that are available from a simple hardware-based solution. This tool was originally developed to help create BoMs for customer-specific designs.
Release 9. The tool accounts for the network topology, the fiber types and lengths, and current and future traffic demand. Cisco Transport Planner can also manage the scalability requirements and enable an in-service upgrade to add new directions and new traffic patterns to an existing design. Depending on the traffic matrix and the wavelength routing some locations will dictate a complete ROADM card, while at some you could optimize the cost by having a ROADM with fewer wavelengths activated.
The Cisco Transport Planner Release 9. Consequently, the omni-directional demand can be launched or received in or from any direction in a certain node. Consequently, the user can tune to a different wavelength or color to overcome possible wavelength routing or assignment constraints.
Individually and together these two features provide a enormous flexibility and resilience against failures.
