The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

A Survey of Green Networking Research (2010, background): “Besides the choice between an idle and a working mode, most of today’s technologies propose a wider range of possibilities through the use of several transmission rates [21], [22], [26], to which different energy consumption ﬁgures correspond.”
On the design of green reconfigurable router toward energy efficient internet (2011, background): “In addition, the impact of link utilization on power consumption is considered minimal [8].”
Energy proportional datacenter networks (2010, methodology): “The ethernet ALR work [8] proposes similar ideas using eth-ernet, and evaluates them with an analytic model and simulation using synthetic trafﬁc patterns.”
