Worst-Case Analysis of Dynamic Wavelength Allocation in Optical Networks

This white paper considers Wavelength Division Multiplexed WDM optical networks. WDM networks use multiple communication channels over a single optical fiber. The channels are at different wavelengths. These networks support lightpaths, which are end-to-end circuit-switched communication connections that traverse one or more links and use one WDM channel per link.
