The unprecedented growth of the global Internet traffic, coupled with the large spatio-
temporal fluctuations that create, to some extent, predictable tidal traffic conditions, are …

A detailed survey of approaches reducing energy consumption of core networks is
presented in this paper. We consider a multilayer architecture, in which the optical layer can …

This paper deals with an energy saving routing solution, called Energy Saving IP Routing
(ESIR), to be applied in an IP network. ESIR operation is integrated with Open Shorthest …

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 …

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 convergence of computer-communication networks towards an all-IP integrated network
has transformed Internet in a commercial commodity that has stimulated an un-precedent …

The growing popularity of high-speed mobile communications, cloud computing, and the
Internet of Things (IoT) has reinforced the tidal traffic phenomenon, which induces spatio …

Energy consumption of large-scale networks has become a primary concern in a society
increasingly dependent on information technology. Novel solutions that contribute to …

The energy crisis and environmental protection are gaining increasing concern in recent
years. ICT (Information and Communication Technology) has a significant impact on the total …

Core networks offer high capacities, thanks mainly to the optical technologies they utilize,
but they consume a non-negligible amount of energy. The traffic volume in metro and core …
