  • Abstract
    We present an auto-defragmentation method to continuously `defrag´ flexible grid optical networks without service disruption. Signal dependency map is introduced to identify candidate signals to be retuned and their retune sequence. Simulation results show up to 76% reduction in request blocking and 38% reduction in the number of stranded slots.
