Book Description
This book takes a pragmatic approach to deploying state-of-the-art optical networking equipment in metro-core and backbone networks. The book is oriented towards practical implementation of optical network design. Algorithms and methodologies related to routing, regeneration, wavelength assignment, sub rate-traffic grooming and protection are presented, with an emphasis on optical-bypass-enabled (or all-optical) networks. The author has emphasized 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. This new edition contains: new chapter on dynamic optical networking and a new chapter on flexible/elastic optical networks. Expanded coverage of new physical-layer technology (e.g., coherent detection) and its impact on network design and enhanced coverage of ROADM architectures and properties, including colorless, directionless, contentionless and gridless. Covers ‘hot’ topics, such as Software Defined Networking and energy efficiency, algorithmic advancements and techniques, especially in the area of impairment-aware routing and wavelength assignment. Provides more illustrative examples of concepts are provided, using three reference networks (the topology files for the networks are provided on a web site, for further studies by the reader). Also exercises have been added at the end of the chapters to enhance the book’s utility as a course textbook.

Book Description
A strategic guide to the practical business applications of optical networking technologies Optical Networking A Wiley Tech Brief Optical networks are spreading outward from Internet backbones to cities to corporations and even to the home. Cities are in a strategic position to create a leading-edge optical infrastructure that will drive economic growth. Optical technologies can cost-effectively meet corporate bandwidth needs today and tomorrow, from optical Internet connections offering bandwidth on demand to fiber on the LAN. Fiber to the home can provide true broadband connectivity for telecommuters as well as converged multimedia offerings for consumers. The ever-expanding need for bandwidth can only be met by optical networks and their phenomenal data capacity. In this book, the real-world applications driving optical networking deployments are explored. You'll get a detailed look inside the markets for fiber, bandwidth supply and demand, and optical networking technology. Both traditional architectures, such as SONET, and emerging paradigms, such as IP over DWDM and Gigabit Ethernet, are examined. This book provides practical information, insight, and case studies about the business benefits and broad range of optical networking technologies and applications available today, including: * Optical internets that run IP directly over fiber without intervening layers of ATM and SONET * Municipal optical networks and their ability to transform local economies * Corporate optical networking deployments, from LAN to WAN to Internet connections * Gigabit Ethernet and bandwidth on demand * Fiber to the home-and why pseudobroadband alternatives such as DSL and cable modems are inadequate * Why wireless is not an alternative to fiber Wiley Tech Briefs Focused on the needs of the corporate IT and business manager, the Tech Briefs series provides in-depth information on new or emerging technologies, solutions, and vendor offerings available in the marketplace. With their accessible approach, these books will help you get quickly up-to-speed on a topic so that you can effectively compete, grow, and better serve your customers.

Book Description
Plan, design, and configure high-speed fiber-optic networksCoverage includes: Configuring ONS 15454 and ONS 15327 platforms Architecture for building Metropolitan Ethernet Transparent LAN Services (TLS) Packet over SONET (PoS) network design, configuration, and verification Inner workings of dense wavelength division multiplexing (DWDM), including operability with the ONS 15216 product family Principles of Dynamic Packet Transport (DPT) SONET background, including structures, components, and network design Bonus case studies, which challenge you to select equipment and design a metro optical network Fiber-optic networking has several significant advantages over traditional wired and wireless networks: optical signals can travel much farther than electrical signals, are more secure, are resistant to electromagnetic interference, and have the potential to provide bandwidth in the terabits per second range (1000 Gbps). Service providers must satisfy the always-increasing networking demands of customers while keeping costs to a minimum. Optical networks must meet the challenge of supporting multiple types of transmissions including voice, video, and data traffic. Although time-division multiplexing (TDM) has provided a growth path for services, it is more constrained than IP + Optical strategies like the Cisco Dynamic Packet Transport (Resilient Packet Ring). The Cisco Systems(R) end-to-end IP + Optical networking strategy provides an intelligent converged network in which optical infrastructures can be used to their fullest potential. While most reference books focus on the theory involved in SONET and optical infrastructures, "Cisco Self-Study: Building Cisco Metro Optical Networks (METRO)" focuses on the practical application of planning and configuring optical networks that involve SONET, DWDM, Metropolitan Ethernet, Packet over SONET, and Dynamic Packet Transport (Resilient Packet Ring). "Cisco Self-Study: Building Cisco Metro Optical Networks (METRO)" is part of a recommended learning path from Cisco Systems that can include simulation and hands-on training from authorized Cisco Learning Partners and self-study products from Cisco Press. To find out more about instructor-led training, e-learning, and hands-on instruction offered by authorized Cisco Learning Partners worldwide, please visit www.cisco.com/go/authorizedtraining.This volume is in the Certification Self-Study Series offered by Cisco Press.
