Optical Network Design

Optical networks form the foundation of the global network infrastructure; hence, the planning and design of optical networks is crucial to the operation and economics of the Internet and its ability to support critical and reliable communication services. This book chapter covers various aspects of optimal optical network design, such as wavelength-routed Wavelength Division Multiplexing (WDM) optical networks, Spectrum-Sliced Elastic (SLICE) optical networks. As background, the chapter first briefly describes optical ring networks, WDM optical networks, and SLICE optical networks, as well as basic concepts of routing and wavelength assignment and virtual topology design, survivability, and traffic grooming in optical networks. The reader is referred to additional references for details. Many optical network design problems can be formulated as sophisticated optimization problems, including (1) Routing and Wavelength Assignment (RWA) and virtual topology design problem, (2) a suite of network design problems (such as variants of traffic grooming, survivability, and impairment-aware routing), (3) various design problems aimed at reducing the overall energy consumption of optical networks for green communication, (4) various design optimization problems in SLICE networks that employ OFDM technologies. This chapter covers numerous optical network design optimization problems and solution approaches in detail and presents some recent developments and future research directions.
