A study on energy savings potential of data network equipment for a green Internet

초록

A green Internet is becoming a major concern recently. The main concept of it is to improve energy efficiency in the Internet for reduction of unnecessary energy consumption. Generally, energy consumption of data network equipment in the Internet is unknown although they use a substantial amount of energy. In this area, there is a lack of deeper related studies with a special focus on wired networking and it still remains to be many challenges. This paper aims at exploring an impact of data network equipment for greening the Internet. We first introduce backgrounds and motivations of green networking on aspect of energy consumption. Secondly, we estimate energy consumption and energy savings potential of data network equipment in detail. Thirdly, we assess impacts of it based on IP traffic type and propose new viewpoint on energy efficiency focused on the QoS. Lastly, we propose the future works for green networking from the perspective of QoS. © 2014 Global IT Research Institute (GIRI).
