Green IP over WDM mesh networks with connection availability guarantee

Green IP over WDM mesh networks with connection availability guarantee Energy efficiency has been well recognized as an important objective in IP over WDM mesh networks. In this paper, we study the problem of green IP over WDM mesh networks with connection availability guarantee under static traffic demands. We first present a virtual link power model for the two-layer networks, which is built on the power consumption value of the commercial network devices. Based on the energy-aware two-layer auxiliary graph, we propose a new heuristic algorithm named Availability-Guaranteed Energy-Efficient Design for Two-Layer Optical Networks (AGED_TON). The AGED_TON algorithm first constructs initial energy-efficient virtual topology on which connection requests are carried, and then routes working path and backup path of lightpaths on physical topology. In the procedure of AGED_TON algorithm, connection availability is considered for path calculating to achieve a good tradeoff between connection availability and energy efficiency. Compared with previous green networking algorithms, our proposed AGED_TON algorithm reduces energy consumption significantly and guarantees connection availability at the satisfactory level. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Photonic Network Communications Springer Journals

Abstract

Energy efficiency has been well recognized as an important objective in IP over WDM mesh networks. In this paper, we study the problem of green IP over WDM mesh networks with connection availability guarantee under static traffic demands. We first present a virtual link power model for the two-layer networks, which is built on the power consumption value of the commercial network devices. Based on the energy-aware two-layer auxiliary graph, we propose a new heuristic algorithm named Availability-Guaranteed Energy-Efficient Design for Two-Layer Optical Networks (AGED_TON). The AGED_TON algorithm first constructs initial energy-efficient virtual topology on which connection requests are carried, and then routes working path and backup path of lightpaths on physical topology. In the procedure of AGED_TON algorithm, connection availability is considered for path calculating to achieve a good tradeoff between connection availability and energy efficiency. Compared with previous green networking algorithms, our proposed AGED_TON algorithm reduces energy consumption significantly and guarantees connection availability at the satisfactory level.
