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.
