Energy Efficient Design and Routing for IP over Dynamic Optical Networks

Not Accessible

Your library or personal account may give you access


A MILP based optimization model called PVTR is proposed for energy reduction in IP over dynamic optical networks. By periodical virtual topology reconfiguration, it is able to dynamically switch off unnecessary networking equipments, and reduce the energy consumption caused by over-provision. Simulation results indicate that the proposed approach can significantly improve network performance, and is proved to be a suitable manner for energy saving.
