In this paper, we study the energy efficient problem of survivable IP over WDM networks. A novel ''virtual link'' energy model is presented. The energy model is abstracted from the power consumption value of commercial network devices. Based on the new two-layer energy-aware auxiliary graph, we propose the Energy-Efficient and Survivable Routing (E^2SR) algorithm for IP over WDM networks against double-link failures. In contrast to prior green networking algorithms, the novelty of our proposed routing algorithm is mainly twofold: first, the energy-efficient virtual topology iterative mapping method; second, the energy-efficient spare resource sharing method. From the numerical results for two typical carrier networks, our proposed E^2SR algorithm achieves obvious energy consumption reduction for IP over WDM networks when guaranteeing traffic survivability against double-link failures.
