Engineering View of Green Networking: Design Features

The reduction of energy consumption has become a key issue for industries, because of economical, enviromental and marketing reasons. Data – centers and networking infrastructure involve high – performance and high – availability machines. They therefore rely on powerful devices, which require energy – consuming air conditioning to sustain their operation, and which are organized in a redundant architecture. In recent years, valuable efforts have indeed been dedicated to reducing unnecessary energy expenditure, which is usually nicknamed as a greening of the networking technologies and protocols.
