The year-by-year increase in electricity consumption significantly affects all nations today
from environmental, social, and economic perspectives. Various studies show that, among …

The evaluation of and reduction in energy consumption of backbone telecommunication
networks has been a popular subject of academic research for the last decade. A critical …

We estimate potential energy savings in IP-over-WDM networks achieved by switching off
router line cards in low-demand hours. We compare three approaches to react on dynamics …

As Internet traffic is estimated to substantially grow in the near future, one of the most
challenging issues will concern the reduction of its power requirement. For the core/transport …

With increasing energy consumption of the Internet, it is now imperative to design energy-
efficient network architectures and protocols. Optical technologies have significant promise …

Traffic grooming and multipath routing are two techniques that are widely adopted to
increase the performance of traditional wavelength division multiplexed networks. They …

We estimate potential energy savings in IP-over-WDM networks achieved by switching off
router line cards in low-demand hours. We compare three approaches to react on dynamics …

Rising energy costs and climate change have led to an increased concern for energy
efficiency (EE). As information and communication technology is responsible for about 4% of …

Efficiency in energy consumption is attracting greater and greater attention in recent years to
the point that it is becoming one of the major constraints steering the evolution of our society …

In this work we propose a strategy to minimize the impact of energy saving techniques on
the performance of an Internet Service Provider network. We study the problem of putting in …
