Abstract
The key issue of this paper is the power management of Internet access devices. The paper commences with an outline on the energy consumption of today's IT devices. It is followed by a description of options to increase energy efficiency of computers. The paper proves that in practice network cards and other IT network components, such as modems, network access points, switches and routers have the maximum energy consumption - irrespective of their current workload. One approach is to reduce the transmission rate of the concerned IT devices, in case of low network load. For this, two techniques are available today: Auto Negotiation (today's standard) and ALR, Adaptive Link Rate (currently being developed). These two techniques are illustrated more closely in a further part of this paper. In particular the forward-looking ALR-technique is outlined to show its opportunities and boundaries. The paper concludes with a summary.
