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 …

A capital expenditure model is a key requirement to evaluate multilayer (ML) metro and core
network architectures. Based on the Internet protocol/multiprotocol label switching …

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 …

Implementing energy-efficient CPUs and peripherals as well as reducing resource
consumption have become emerging trends in computing. A landmark for researchers in …

As the services in elastic optical networks (EONs) are bandwidth-intensive, unpredictable
and dynamic, increasing network factors are emerging to affect the performance of network …

Single and multi-carrier networks offering channel rates up to 400 Gb/s are evaluated under
realistic reach parameters. It is found that efficient spectrum utilization and fine bit-rate …

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

Elastic optical networking (EON) is a solution that promises to improve infrastructure
