Intended for network planners and graduate students, this handbook describes protocols for optical network architectures, routing and wavelength assignment in WDM networks, and connection and resource management in optical communication networks. The issue of survivability in networks and some enabling technologies are also addressed. Topics of the 21 chapters include the evolution of an optical broadband services network, multiprotocol label switching, dynamic synchronous transfer mode, schemes for adaptive routing, dynamic lightpath restoration in WDM mesh networks, fiber optic sensors, and types of wavelength converters.
