Multiwavelength Optical Networks: A Layered Approach

The book presents four architecture categories, in increasing order of complexity: *Shared channel networks, which use optical multiplexing and multiple access to provide multipoint connectivity on a static optical layer *Wavelength-routed networks, which use optical switching to provide point-to-point connectivity over a reconfigurable optical layer *Linear lightwave networks, which support multipoint connectivity over a reconfigurable optical layer *Hybrid, logically routed networks, using electronically switched overlays to provide virtual connectivity on a reconfigurable optical layer Procedures for network control and design are covered for each category of network and are illustrated with examples. The emphasis here is on the fundamental role of available network resources--optical spectrum, fiber topology, and switching node and access station functionality--in determining network performance. Important topics covered are: *Multiplexing and multiple access in the optical domain *Effective techniques for physical layer simulation *Optical switch designs to circumvent component imperfections, plus coverage of optical layer packet switching *New and efficient algorithms for routing and wavelength assignment *Combining the advantages of optical transparency and electronic switching *Network survivability and fault recovery *Recent commercial trends in multiwavelength optical networking and practical deployment issues that may arise, including cost, flexibility, and performance tradeoffs 020130967XB04062001
