Enabling Sleep Mode in Backbone IP-Networks: A Criticality-Driven Tradeoff

The energy consumption of network devices, and, as a consequence, of communication networks, is generally independent from their level of utilization, which results in a waste of energy when the network is lightly loaded. Ideally the consumption of a network should be proportional to the amount of traffic it conveys. The most straightforward way to enforce such a proportionality between the network energy consumption and its utilization level, is to dynamically adapt the status of network devices to the load, forcing a subset of them to enter a sleep state during the low activity periods. The authors present in this paper an algorithm to dynamically put links into a sleep state, based on a cooperative-game approach, named "L-Game".
