A General Framework for Achieving Energy Efficiency in Data Center Networks

The popularization of cloud computing has brought a concern over the energy consumption in data centers. In addition to the energy consumed by servers, the energy consumed by the large number of network devices emerges as a significant problem. Existing work on energy-efficient data center networking primarily focuses on traffic engineering, which is usually adapted from traditional networks. The authors propose a new framework to embrace the new opportunities brought by combining some special features of data centers with traffic engineering. Based on this framework, they characterize the problem of achieving energy efficiency with a time-aware model, prove its NP-hardness and solve it in two steps.
