Green Traffic Engineering for future core networks

The achieving of the best ratio of performance to energy consumption and at the same time assuring manageability is an important goal towards the design of Future Networks. This paper presents a general problem formulation for Energy-Aware Traffic Engineering (ETE) and proposes a distributed, heuristic ETE scheme that provides load balancing and energy-awareness in accordance with the operator's needs. Simulation results of ETE compared to the optimal network performance confirm the capability of ETE to meeting the needs of Future Networks.
