title: Green optical networks with connection availability guarantee.
abstract: In this paper, we study green optical networks with connection availability guarantee. After introducing a power consumption model for green optical network design, we propose a design method called Availability-Guaranteed Energy-Efficient Design (AGEED). In AGEED, we employ dedicated path protection as backup capacity in order to improve connection availability. Based on iterative routing by modifying link weights, we can make idle network resources be switched into sleep mode, and obtain the energy saving effect. Our simulation results show that AGEED is more advantageous to achieve energy-efficient purpose and guarantee the satisfied connection availability levels in comparison with other methods.
