This paper studies a traffic grooming in wavelength-division multiplexing (WDM) mesh networks for the SONET/SDH streams requested between node pairs. The traffic could be groomed at the access node before converting to an optical signal carried in the All-Optical network. We design a virtual topology with a given physical topology to satisfy multiple(More)
Reconfiguration in a Wavelength-Routed Optical Network is a process of rearranging a virtual topology to meet traffic demands that change over a period of time. This dissertation studies a series of reconfigurations corresponding to a series of changes in traffic demand matrices. A change in a virtual topology is costly in terms of traffic disruption.(More)
