Energy-aware routing based on power profile of devices in data center networks using SDN

ICT is currently responsible for 4% of the EU's carbon emission. In this industry, data centers are growing quickly to supply the escalating services and application demands. The design of high performance and energy-efficient data center networks is an important issue while still being confronted with many challenges such as scalability, reliability, etc. On the other hand, the network devices' difference in power consumption as well as property make the researching process more difficult to construct a routing algorithm that effectively works with various devices. This paper presents a novel energy-saving scheme that can flexibly control and route traffic relying on the difference of network devices' energy-profile. By using Open Flow mechanism and Net-FPGA cards based on Software Defined Networks, we successfully deploy energy-aware data center network, and its experimental results show that the novel scheme improves the power saving level and energy-efficiently works based on the switches' energy-profile.
