Abstract
Energy consumption in network resources, such as router and switches, are increasing rapidly, due to the exploiding number of Internet users and network transmission speed. In the next 10 to 15 years the Internet will undergo a substantial increase especially with respect to the bandwidth required by end-users. Since the current Internet already consumes a not-negligible percentage of the total world electricity, It is obvious that reducing power consumption in the network is a crucial issue hereafter. This paper proposes a traffic management policy to reduce the energy consumption by the network devices. Reducing energy consumption has been an important part of networking research, with th most prominent topics pertaining to the energy consumption of servers and wireless devices. Unfortunately, the energy consumption of wired networks has been traditionally overlooked. The Internet users have been increasing 28% every year. Real-time traffic reaches nearly 14Tbps, the power consumption of network equipments has been extremely increasing. In 2008, the ICT power consumption grew 168GW and in 2020, it would be 430GW (newarly 2.6 times), that is nearly 8% increasing rate. In 2008, the power consumption of network equipments was 25GW and in 2020, it would grow up to 97GW (newarly 4 times), that is nearly 12% increasing rate. In Japan, the power consumption of routers is nearly 3.6 GW in 2010. So, IETF had started to discuss power consumption problem. The underlying network infrastructure, namely routers, switches and other network devices, still lacks effective energy management solutions. This paper proposes a traffic management policy to reduce the energy consumption by the network devices.
