Various static resource allocation algorithms have been used in WDM networks to allocate resources such as wavelength channels, transmitters, receivers, and wavelength converters to a given set of static lightpath demands, based on certain design objectives. However, although optimized resource allocations can be obtained, it remains an open issue how to determine which resources are bottlenecks to...
We propose a novel link-based formulation of the WDM network reconfiguration problem for the semi-dynamic scenario, where reconfigurations are required in a series of sessions as traffic demands vary. Each reconfiguration session must consider existing connections obtained from the previous reconfiguration session. We coordinate the reconfiguration of existing connections with the new traffic demands...
