Routing and Wavelength Assignment for Survivable Wavelength-Routed Networks,wing reasons [52]: (a) the optical layer can efficiently multiplex protection resources (such as spare wavelengths and fibers) among several higher-layer network applications, and (b) survivability at the optical layer provides protection to higher-layer protocols that may not have built-in fault re

ould make telecommunication networks more efficient. Wavelength-routing has been one of the most important technologies to em­ ploy WDM in backbone networks. In wavelength-routed WDM networks, optical channels, which are referred to as lightpaths, are set up between WDM terminals. Most chapters of this bock a978-1-4613-5029-3978-1-4615-0341-5

Path-Protection Routing and Wavelength Assignment with Duct-Layer Constraints,This chapter further investigates the RWA problem in wavelength-routed WDM mesh networks. A new set of constraints, duct-layer constraints, are introduced. We develop ILP formulations and heuristic algorithms to solve the RWAproblem for path-protection schemes under duct-layer constraints.
