Abstract :
We propose several algorithms to achieve hitless bandwidth defragmentation using spectrum retuning in elastic optical networks. Two retuning techniques, spectrum sweeping and hop tuning, are studied. Simulation results show that the hop tuning technique achieves better defragmentation performance.
