Dynamic on-demand lightpath provisioning using spectral defragmentation in flexible bandwidth networks

We propose a spectral defragmentation algorithm and corresponding node architectures with wavelength conversion to support on-demand lightpath provisioning in flexible bandwidth optical networks. Simulation results demonstrate six-fold reductions in blocking rates with defragmentation.
