Energy-Aware Resource Adaptation for Next-Generation Network Equipment

Abstract

Besides a more widespread sensitivity to ecological issues, the \ninterest in energy-efficient network technologies springs from \nheavy and critical economical needs, since both energy cost and \nnetwork electrical requirements show a continuous growth, with \nan alarming trend over the past years. In this contribution, we \nexplore and try to evaluate the feasibility and the impact of power \nmanagement policies able to well suit a heterogeneous set of \nhighly modular architectures, generally used for developing \ntoday’s network equipment. The proposed policies aim at \noptimizing the power consumption of each device component \nwith respect to its expected network performance. Finally, in \norder to provide an experimental evaluation of the proposed ideas, \nwe applied such power management policies to a new generation \nSW router platform, and we evaluated it with real traffic traces.
