Joint Virtual Machine Assignment and Traffic Engineering for Green Data Center Networks
The popularization of cloud computing brings emergency concern to the energy consumption in big data centers. Besides the servers, the energy consumed by the network in a data center is also considerable. Existing works for improving the network energy efficiency are mainly focused on traffic engineering, i.e., consolidating flows and switching o unnecessary devices, which fails to comprehensively consider the unique features in data centers. In this paper, the authors advocate a joint optimization for achieving energy efficiency of data center networks by proposing a unified optimization framework.
